Key Messages
- The aim of this guide is to provide general guidance on key steps and
factors for agencies and organisations to consider when responding to a
personal information security breach.
- Agencies and organisations have obligations to have reasonable security
safeguards in place and to take reasonable steps to protect the personal
information they hold from misuse, loss and from unauthorised access,
modification or disclosure.
- Personal information security breaches are not limited to malicious
actions, such as theft or "hacking", but may arise from internal errors
and failures to follow information handling policies, causing accidental
loss or disclosure.
- In general, if there is a real risk of serious harm as
a result of a personal information security breach, the affected
individuals should be notified.
- Notification can operate as an important mitigation strategy for
individuals and it promotes transparency and trust about the organisation
or agency.
- There is no specific requirement in the Privacy Act to notify
individuals when and if a breach has occurred.
- Notification of a breach in appropriate circumstances is consistent
with good privacy practices.
- Compliance with this voluntary guide is recommended. It is not
mandatory.
- The operation of this guide could inform the Government response to the
Australian Law Reform Commission's August 2008 recommendation that
mandatory breach notification be introduced into law.
Key terms used in this guide
Privacy Act
Refers to the Privacy Act 1988 (Cth)
Personal information
Has the meaning as set out in s6 of the Privacy Act:
personal information means information or an opinion (including information
or an opinion forming part of a database), whether true or not, and whether
recorded in a material form or not, about an individual whose identity is
apparent, or can reasonably be ascertained, from the information or
opinion.
Personal information security breach
Has the meaning as given in section 4 of this Guide.
IPPs
The Information Privacy Principles (IPPs) set out in s14 of the Privacy
Act. Australian and ACT government agencies must comply with the IPPs.
NPPs
The National Privacy Principles (NPPs) set out in Schedule 3 of the
Privacy Act. In general, the NPPs apply to all businesses and
non-government organisations with a turnover of more than $3 million, all
health service providers and a limited range of small businesses.[1]
TFNs
Tax File Numbers. The Privacy Act includes provisions relating to TFNs
in Part III. The Office has issued Guidelines under s17 of Privacy Act to
regulate the use of TFNs.
1. The purpose of this guide
This guide has been developed to assist agencies and organisations to
respond effectively to a personal information security breach. In particular,
the guide explains when an effective response to a personal information
security breach might include notification of individuals affected by the
breach.
The Office has developed this guide to respond to requests for advice from
agencies and organisations, and in recognition of the global trends towards
breach notification. Breach notification has been introduced as law in many
states in the United States and is being considered by other countries
including Australia. This voluntary guide has been informed by voluntary
guidelines developed by the Privacy Commissioner of Canada and the Privacy
Commissioner of New Zealand.[2]
The guidance provided is not intend to supplant the need for mandatory
breach notification, in certain circumstances, to be entered into law. Such
a measure has been proposed by the Australian Law Reform Commission in August
2008.
2. Scope of this guide
Breach notification is one particular option in responding to a personal
information security breach. However a key challenge is to determine in
what circumstances it is an appropriate response. While establishing
appropriate thresholds for requiring breach notification can be considered
good privacy practice, the steps and actions outlined in the guide are not
specifically required under the Privacy Act 1988 (the Privacy Act).
Therefore, compliance with this guide is voluntary.
The aim of this guide is to provide general guidance on key steps and
factors for agencies and organisations to consider when responding to a
personal information security breach, without the sole focus being
notification of breaches.
The guide encourages a risk-analysis approach so that agencies and
organisations evaluate a breach on a case-by-case basis and make decisions on
actions to take according to their own assessment of risks and
responsibilities in their particular circumstances.
The guide also highlights the importance of preventative measures as part
of a holistic information security plan.
It is important to note that, while the guidance is not mandatory and is
of an advisory nature only, agencies and organisations do have binding legal
obligations under the Privacy Act to secure personal information, as set out
in the Information Privacy Principles (IPPs) and National Privacy Principles
(NPPs).
It is not intended that the advice in this guide be limited to personal
information security breaches that are breaches of IPP4 or NPP4[3]. Rather, the guide is intended
to extend to any situation where personal information has been compromised.
3. Who should use this guide?
This guide has been developed for use by Australian and ACT Government
agencies and private sector 'organisations'[4] that handle personal information. As well
as businesses, organisations in the not-for-profit, community and charity
sectors may find the guide useful.
The guide may also be useful to small businesses that have obligations
under Privacy Act, including those small businesses that may only be covered
by the NPPs in respect of some of their activities[5] or are covered by the credit reporting
provisions of Part IIIA of the Privacy Act.
Government agencies of the states and the Northern Territory, as well as
private sector businesses not covered by the Privacy Act, may find the guide
helpful in outlining good privacy practice. However, the Privacy
Commissioner would not have a role in receiving notifications about personal
information security breaches from these entities.
State and Northern Territory government agencies should also consider the
role of relevant Privacy or Information Commissioners in their own
jurisdictions.
4. What is a personal information security breach?
A personal information security breach occurs when personal information is
subject to loss or unauthorised access, use, disclosure, copying or
modification.
The use of the term 'personal information security' breach is consistent
with the Privacy Act, which regulates the handling of personal information.
This term is used in preference to the term 'data' which is generally not
used in the Privacy Act.[6]
Personal information security breaches can occur in a number of ways.
Some of the most common breaches happen when personal information held by an
agency or organisation is lost, misused, mistakenly disclosed or stolen.
Some examples include:
- lost or stolen laptops, removable storage devices, or physical files
containing personal information
- paper records inadequately recycled or left in garbage
- computer hard drives and other storage media being disposed of without
erasing contents
- an agency or organisation mistakenly providing personal information to
the wrong person, for example by sending details out to the wrong
address
- an individual deceiving an agency or organisation into improperly
releasing the personal information of another person
- databases containing personal information being 'hacked' into or
otherwise illegally accessed by individuals outside of the agency or
organisation and
- employees accessing personal information outside the requirements of
their employment.
It is important to recognise that personal information security breaches
are not limited to external malicious actions, such as theft or 'hacking',
but may just as often involve internal errors and failures to follow
established information handling procedures. While there may be no harm
intended, these types of breach can affect individuals' privacy as much as
malicious actions.
5. Prevent personal information security breaches
Security is a basic element of information privacy.[7] In Australia, this principle is reflected
in the Privacy Act in both the IPPs and the NPPs.
5.1 Obligations under the Privacy Act
The IPPs regulate the way most Australian and ACT Government agencies
handle personal information. These principles cover the collection,
storage, use, disclosure and access obligations of those agencies.
The NPPs regulate the way private sector organisations handle personal
information. These principles cover collection, storage, use, disclosure
and access obligations of organisations covered by the Privacy Act. In
general the NPPs apply to all businesses and non government organisations
with a turnover of more than $3 million, all health service providers and a
limited range of small businesses.[8]
Agencies and organisations are required to take reasonable steps to
protect the personal information they hold from misuse and loss and from
unauthorised access, modification or disclosure. This requirement is set
out in IPP 4 for public sector agencies and NPP 4 for private sector
organisations.[9] (See
Appendix A for IPP4 and NPP4.)
Section 18G(b) of the Privacy Act imposes equivalent obligations on credit
reporting agencies and all credit providers. Similarly, guideline 6.1 of the
statutory guidelines regulating Tax File Numbers (TFN) requires TFN
recipients to afford TFNs security safeguards as are reasonable in the
circumstances.
5.2 Other obligations
Many agencies are subject to agency-specific legislative requirements that
add further protections for personal information (such as secrecy
provisions), as well as legislative and other requirements which apply more
generally across government.[10] These other requirements can include the Australian
Government's Protective Security Manual and the Information and
Communications Technology Security Manual (also known as ACSI 33).
Organisations may also be subject to additional obligations through
sectoral specific-legislation in respect of particular information they
hold. For example, Part 13 of the Telecommunications Act 1997
(Cth) sets out obligations on the telecommunications industry in
relation to the handling of certain telecommunications-related personal
information. Some organisations may also have common law duties relating to
confidentiality of particular information.
These additional obligations need to be considered by agencies and
organisations when taking steps to prevent or respond to personal information
security breaches.
5.3 Considerations for keeping information secure
While the focus of this guide is the process of responding to a personal
information security breach agencies and organisations should aim to avoid
such breaches in the first place by ensuring that they have appropriate
security safeguards in place consistent with IPP4 or NPP4.
Some of the information in Step 4 of the guide (see page 32) could equally
be used by agencies or organisations as a way of assessing what security
measures they should have in place to avoid a breach occurring.
What are reasonable steps to secure personal information will depend on
context, including:
- the sensitivity to the individual of the personal information the
organisation holds
- the harm that is likely to result to people if there is a breach of
their personal information
- the potential for harm (reputational or other damage) to the agency or
organisation if the personal information in question were breached
- how the agency or organisation stores, processes and transmits the
personal information (for example, paper-based or electronic records, or
using a third party service provider).
Appropriate security safeguards for personal information need to be
considered across a range of areas. This could include maintaining physical
security, computer and network security, communications security and
personnel security. To meet their information security obligations,
agencies and organisations should consider the following steps:
- risk assessment - identifying the security risks to
personal information held by the organisation and the consequences of a
breach of security
- policy development - developing a policy or range of
policies that implements measures, practices and procedures to reduce the
identified risks to information security
- staff training - training staff and managers in
security and fraud awareness, practices and procedures and codes of
conduct
- the appointment of a responsible person or position -
creating a designated position within the agency or organisation to deal
with personal information security breaches. This position could have
responsibility for establishing policy and procedures, training staff,
co-ordinating reviews and audits and investigating and responding
breaches
- technology - implementing privacy enhancing
technologies to secure personal information held by the agency or
organisation, including through such measures as access control, copy
protection, intrusion detection, and robust encryption.
- monitor and review - monitoring compliance with the
security policy, periodic assessments of new security risks and the
adequacy of existing security measures, and ensuring that effective
complaint handling procedures are in place
- standards - measuring performance against relevant
Australian and international standards as a guide
- privacy impact assessments - evaluating, in a systemic
way, the degree to which proposed or existing information systems align
with good privacy practice and legal obligations
- audits - undertaking regular audits to detect system
weaknesses and/or breaches and
- appropriate contract management - conducting
appropriate due diligencewhere services are contracted,
particularly in terms of the IT security policies and practices that the
service provider has in place and then monitoring compliance to these
policies through periodic audits.
Further, in seeking to prevent personal information security breaches,
agencies and organisations should consider their other privacy obligations
under the IPPs and NPPs. Some breaches or risks of harm can be avoided or
minimised by not collecting particular types of personal information or only
keeping it for as long as necessary. Consider:
- What personal information is necessary to be
collected? Simply put, personal information that is never
collected, cannot be mishandled and therefore the risk of mishandling is
avoided. Both IPP1 and NPP1 require that agencies and organisations,
respectively, only collect personal information that is necessary for one
or more of their functions or activities. IPP 3 also requires that a
collector of personal information take steps to ensure that the
information collected is relevant to the purpose for which it was
collected.
- How long does the personal information need to be
kept? NPP 4.2 requires organisations to securely destroy or
permanently de-identify information that is no longer needed for the
permitted purposes for which it may be used or disclosed. Although the
IPPs do not contain a similar obligation, agencies should nevertheless
consider retention practices, subject to other applicable record-keeping
requirements such as those contained in the Commonwealth Archives
Act.
6. Why breach notification is good privacy practice
Both the IPPs and the NPPs require that personal information be held
securely. Failure to comply constitutes an interference with privacy under
the Privacy Act.
However, the Privacy Act does not expressly require an agency or
organisation to notify individuals if personal information is subject to a
breach of information security safeguards. In addition, breaches of
personal information may arise from activity that is not regulated by the
Privacy Act, such as acts and practices relating to employee records held by
private sector organisations.[11]
Notifying individuals where a breach affects their personal information is
consistent with good privacy, for these reasons:
- Notification as a reasonable security safeguard: As
part of the obligation to keep personal information secure, notification
may in some circumstances be considered as a reasonable step in the
protection of personal information against misuse, loss or unauthorised
access, modification or disclosure.
- Notification as openness about privacy practices:
Being open and transparent with individuals about how personal
information may be handled is recognised as a fundamental privacy
principle.[12]
Part of being open about the handling of personal information may include
telling individuals when something goes wrong and explaining what has
been done to try to avoid or remedy any actual or potential harm.
- Notification as restoring control over personal
information: Privacy is valued, not only because it underpins
our human dignity but also because it gives individuals a measure of
control in their everyday interactions as to how personal information
about them is handled. To this end, the Privacy Act seeks to ensure that
individuals know why information is collected, what it is used for, who
it is ordinarily disclosed to and provides for rights of access and
correction.
Notification of a breach in appropriate circumstances is consistent with
good privacy practices and is to be encouraged in maintaining a community in
which privacy is valued and respected.
7. Four key steps in responding to a breach
Personal information security breaches can be caused by a variety of
factors, affect different types of personal information and give rise to a
range of actual or potential harms to individuals, agencies and
organisations.
Given this context, it is clear that there is no single way of responding
to a personal information security breach. Each breach will need to be
dealt with on a case-by-case basis, undertaking an assessment of the risks
involved, and using that risk assessment as the basis for deciding what
actions to take in the circumstances.
There are four key steps to consider when
responding to a breach or suspected breach:
Step 1: Contain the breach and do a preliminary assessment
Step 2: Evaluate the risks associated with the breach
Step 3: Consider notification
Step 4: Prevent future breaches
Each of the steps is set out in further detail below.
General tips:
- Be sure to take each situation seriously and move immediately to
contain and assess the suspected breach.
- Breaches that may initially seem immaterial may be significant when
their full implications are assessed.
- Agencies and organisations should undertake steps 1, 2 and 3 either
simultaneously or in quick succession. In some cases it may be
appropriate to notify individuals immediately, before containment or
assessment of the breach occurs.
- The decision on how to respond should be made on a case-by-case basis.
Depending on the breach, not all steps may be necessary, or some steps
may be combined. In some cases, agencies and organisations may choose to
take additional steps that are specific to the nature of the breach.
STEP 1: Contain the breach and do a preliminary assessment
Once an agency and organisation has discovered or suspects that a personal
information security breach has occurred, they should take immediate common
sense steps to limit the breach. These may include
Contain the Breach
|
Take whatever steps possible to
immediately contain the breach.
For example, stop the unauthorised practice, recover the records,
or shut down the system that was breached. If it is not practical
to shut down the system or if it would result in loss of evidence,
then revoke or change computer access privileges or correct
weaknesses in physical or electronic security.
Assess whether steps can be taken to mitigate the harm an
individual will suffer as a result of a breach.
For example, if its detected that a customer's bank account has
been compromised, can the affected account be immediately frozen and
the funds transferred to a new account?
|
Initiate a preliminary
assessment
|
Move quickly to appoint someone to lead
the initial assessment. This person should have sufficient authority
to conduct the initial investigation, gather any necessary
information and make initial recommendations. If necessary, a more
detailed evaluation may subsequently be required.
Determine the need to assemble a team that could include
representatives from appropriate parts of the agency or
organisation.
|
Does anyone need to be notified
immediately?
|
Determine who needs to be made aware of
the breach internally, and potentially externally, at this
preliminary stage.
In some cases it may be appropriate to notify individuals
immediately.
Escalate the matter internally as appropriate, including informing
the person within the agency or organisation responsible for privacy
compliance.
It may also be appropriate to report such breaches to relevant
internal investigations units.
If the breach appears to involve theft or other criminal activity,
notification to police should generally occur.
|
Other matters
|
Be careful not to compromise the
ability of law enforcement agencies to investigate the breach, for
example, by making details of the breach public too early.
Be careful not to destroy evidence that may be valuable in
determining the cause or would allow the agency or organisation to
take appropriate corrective action, and ensure appropriate records of
the suspected breach are maintained, including the steps taken to
rectify the situation and the decisions made.

An example of breach containment and preliminary assessment
An online recruitment agency accepts résumés from jobseekers and makes
these available to recruiters and employers on a password protected website.
A jobseeker whose résumé is on the site forwards the recruitment agency
an email she received which she suspects is a 'phishing' email. The email is
personalised and contains information from her résumé. It contains a number
of spelling mistakes and offers her a job. The email claims that all she has
to do to secure the job is to provide her bank accounts details so she can be
paid.
While 'phishing' is common on the internet, the recruitment agency assigns
a member from its IT team to undertake a preliminary assessment. It is found
that the email is indeed a phishing email. It claims to be from a recruiter
and directs the recipient to a website which asks them to enter further
information. It also installs spyware on the recipient's computer.
The recruitment agency seeks to establish how phishers came to have the
résumé details of the jobseeker. The recruitment agency's preliminary
assessment reveals that the phishers have stolen legitimate user names and
passwords from recruiters who use the site and have fraudulently accessed
jobseeker information.
The IT team escalates the issue internally by informing senior staff
members and quickly contains the breach by disabling the compromised
recruiter accounts. Based on the IT team's preliminary assessment, senior
staff move to evaluate risks associated with the breach and consider what
actions should be taken to mitigate any potential harm.
STEP 2: Evaluate the risks associated with the breach
To determine what other steps are immediately necessary agencies and
organisations should assess the risks to the individual associated with the
breach.
Consider the following factors in assessing the risks:
- (a) What personal information is involved
- (b) What is the context of the information
- (c) Establish the cause and extent of the breach
- (d) Asses what is the risk of harm that could result to individuals
- (e) Identify what other harms or risks could arise
(a) Consider what personal
information is involved
|
Considerations
|
Comments and examples
|
Does the type of information create a
greater risk of harm?
|
Some information is more likely to
cause an individual harm if it is compromised, whether that harm is
physical, financial or psychological. For example, health
information, government-issued identifiers such as Medicare numbers,
driver licence and health care numbers, and financial account numbers
such as credit or debit card numbers might pose a greater risk of
harm to an individual than their name or address.
Also, a combination of personal information typically creates a
great risk of harm than a single piece of personal information.
It may also matter whether the information is permanent or
temporary. Permanent information, such as someone's name place and
date of birth, or medical history cannot be 're-issued'.
The permanence of the information may be more significant if it is
protected by encryption - overtime, encryption algorithms may be
broken, so such information may be at greater longer term risk of
being compromised. On the other hand, temporary information may
have changed by the time an algorithm is broken.
|
Who is affected by the breach?
|
Employees, contractors, the public,
clients, service providers, other agencies or organisations?
Remember that certain people may be particularly at risk of harm.
A personal information security breach involving name and address of
a person might not always be considered high risk. A breach to a
women's refuge database containing name and address information may
expose women who attend the refuge to a violent family member. The
risk may be less if the breach relates to businesses that service the
refuge.
|
(b) Determine the context
of the affected information
|
Considerations
|
Comments and examples
|
What is the context of the personal
information involved?
|
For example, a list of customers on a
newspaper carrier's route may not be sensitive. However, the same
information about customers who have requested service interruption
while on vacation may be more sensitive.
While publicly available information such as that found in a
public telephone directory may be less sensitive, this also depends
on context. For example, what might be the implications of
someone's name and phone number or address being associated with the
services offered, or the professional association represented?
To whom was the information exposed? Employee records containing
information about employment history such as performance and
disciplinary matters or a co-worker's mental health might be
particularly sensitive if exposed to other employees in the workplace
and could result in an individual being the subject of humiliation or
workplace bullying.
|
Have there been other breaches that
could have a cumulative effect?
|
A number of small, seemingly
insignificant, breaches could have an accumulative effect. Separate
breaches that might not, by themselves, be assessed as representing a
real risk of serious harm to an affected individual, may meet this
threshold when the accumulative affect of the breaches is considered.
This could involve incremental breaches of the same agency or
organisation's database. It could also include known breaches from
a number of different sources.
|
How could the personal information be
used?
|
Could the information be used for
fraudulent or otherwise harmful purposes, such as to significantly
embarrassing the individual?
Could the affected information be easily combined either with each
other or with readily publicly available information to create a
greater risk of harm to the individual?
|
(c) Establish the cause and
extent of the breach
|
Considerations
|
Comments and examples
|
Is there a risk of ongoing breaches or
further exposure of the information?
|
What was the extent of the unauthorised
access to or collection, use or disclosure of personal information,
including the number and nature of likely recipients and the risk of
further access, use or disclosure, including via mass media or
online?
|
Is there evidence of theft?
|
Is there evidence that suggests theft,
and was the information the target? For example where a laptop is
stolen can it be determined whether it was the information on the
laptop or the laptop itself that the thief wanted?
Evidence of theft could suggest a greater intention to do harm and
heighten the need to provide notification to the individual, as well
as possible law enforcement.
|
Is the personal information adequately
encrypted, anonymised or otherwise not easily accessible?
|
Is the information rendered unreadable
by security measures in place to protect the stored information? Is
the personal information displayed or stored in such a way so that it
cannot be used if breached?
For example, if a laptop containing adequately encrypted
information is stolen, subsequently recovered and investigations show
that the information was not tampered with, notification to
individuals may not be necessary.
|
What was the source of the breach?
|
For example, did it involve external or
internal malicious behaviour, or was it an internal processing
error? Does it seem to have been lost or misplaced?
The risk of harm to the individual may be less where the breach is
unintentional or accidental, rather than intentional or malicious.
For example the client may have a common surname which leads a
staff member to accidentally access the wrong client record. The
access records show that the staff member immediately closed the
client record once they became aware of their mistake. The risk of
harm will be less in this case than in the case where a staff member
intentionally and deliberately opened a client's record to browse the
record, or to use or disclose that information without a legitimate
business reason for doing so.
|
Has the personal information been
recovered?
|
For example, has a lost laptop been
found or returned? If the information has been recovered, are there
any signs that it has been tampered with?
|
What steps have already been taken to
mitigate the harm?
|
Have the agency or organisation
contained the breach so that its full extent can be assessed? Are
further steps required?
|
Is this a systemic problem or an
isolated incident?
|
When checking the source of the breach,
it is important to check whether any similar breaches could have
occurred in the past. Sometimes, a breach can signal a deeper problem
with system security. This may also reveal that more information
has been affected than initially thought, potentially heightening the
risk posed.
|
How many individuals' are affected by
the breach?
|
If the breach is a result of a systemic
problem, there may be more people affected than first anticipated.
Even where the breach involves accidental and unintentional misuse
of information; if the breach affects many individuals then this may
create greater risks that the information will be misused. The
agency or organisation's response should be proportionate.
While the number of affected individuals can help gauge the
severity of the breach, it is important to remember that even a
breach involving the personal information of one or two people can be
serious, depending on the information involved.
|
(d) Assess what is the risk
of harm that could result to individuals
|
Considerations
|
Comments and examples
|
Who is the recipient of the
information?
|
Is there likely to be any relationship
between the unauthorised recipients and the affected individuals?
For example, was the disclosure to an unknown party or to a party
suspected of being involved in criminal activity where there is a
potential risk of misuse? Or was the disclosure to a party to which
the individual would object or is the subject of a restraining order.
Or to co-workers who have no need to have this information?
Or was the recipient a trusted, known entity or person that would
reasonably be expected to return the information without disclosing
or using it? For example was the information sent to the
individual's lawyer instead of being sent to them, or to another
party bound by professional duties of confidentiality or ethical
standards.
|
What harm to individuals could result
from the breach?
|
Examples include:
- threat to physical safety
- identity theft
- threat to emotional wellbeing
- financial loss
- loss of business or employment opportunities or
- humiliation, damage to reputation or relationships
- workplace or social bullying or marginalisation.
|
(e) Identify what other
harms or risks could arise
|
Other possible harms
|
Examples include:
- loss of trust in the agency or organisation
- loss of assets
- financial exposure
- regulatory penalties
- extortion
- reputational damage
- legal proceedings.
- risks to national security
- impact on secrecy and access provision
|
An example of evaluating the risks associated with the
breach
A newspaper publisher receives a call from a newsagent that sells its
newspapers. The newsagent says that the address labels on the bundles of
newspapers delivered to his shop appear to show subscriber information
printed on the other side. The information includes names, addresses and
credit card details.
Following a preliminary investigation, the newspaper publisher confirms
that some labels have been inadvertently printed on the back of subscriber
lists.
As a first step to containing the breach, the publisher attempts to
contact newsagencies that have received the newspapers and asks them to check
the labels on the bundles and securely destroy any that show subscriber
details on the back.
With these first steps completed, the newspaper publisher begins to
evaluate the risks associated with the breach.
The information that was involved in the breach was name, address and
credit card information. The newspaper has a large number of subscribers.
Further investigations into the breach are unable to reveal how many
subscribers' details have been exposed.
The bundles of newspapers displaying subscriber information have been
delivered to newsagencies in the early hours of the morning. The newspaper
publisher notes that the subscriber information was therefore at risk of
unauthorised access during the time between delivery and when the newsagents
arrived to open shop.
Further investigations reveal that many newsagencies have already
discarded the labels before checking could be carried out as to whether they
contained subscriber information. This means that, in many cases, the
subscriber lists may not have been safely destroyed.
The newspaper publisher concludes that the exposure of this information
could present a real risk of serious harm (in this case, financial harm) to
many individuals. Based on the conclusion that this is a serious breach,
the publisher moves to notify subscribers. Given the large number of
potentially affected individuals and the risk of serious financial harm, the
publisher also notifies the Privacy Commissioner, particularly as there is a
real possibility that individuals may complain about the breach.
State government agency discovers routine breaches
A state government agency undertakes a periodic audit of user access
records. The audit reveals an unusual pattern of client account enquiries
in one department of the agency. The client records being browsed belong to
well known celebrities and contain address information, along with other
details. The unauthorised viewing has occurred over a 12 month period.
After making further enquiries which included interviewing the relevant
staff, department staff, managers and later the department head, it is
determined that the staff were intentionally browsing client records without
any legitimate business purpose. There is no evidence that this information
has been disclosed to any third party.
However, the agency recognises that the address details may be information
that is not readily available elsewhere, as many of the individuals are
unlikely to have their addresses in other public sources.
On this basis, the agency decides to notify the individuals affected by
the unauthorised browsing. It also takes measures to prevent routine
browsing of records, and to ensure that all staff are aware of their
obligations to act appropriately.
As a state government agency, the jurisdiction of the Privacy Act does not
apply. There is likely to be little purpose in notifying the Privacy
Commissioner. However, in this case, the state does have its own privacy
law and regulator. The state government agency seeks advice from its own
regulator as to whether notification is required.
STEP 3: Consider notification
Notification can be an important mitigation strategy that has the
potential to benefit both the agency or organisation and the individuals
affected by a personal information security breach. The challenge is to
determine when notification is appropriate. While notification is an
important mitigation strategy, it will not always be the appropriate response
to a breach. Providing notification about low risk breaches can cause undue
anxiety and de-sensitise individuals to notice. Each incident needs to be
considered on a case-by-case basis to determine whether breach notification
is required.
In general, if a
personal information security breach creates a real risk of serious harm to
the individual, those affected should be notified.
Prompt notification to individuals in these cases can help them mitigate
the damage by taking steps to protect themselves. Agencies and
organisations should:
- take into account the ability of the individual to take specific steps
to mitigate any such harm
- consider whether it is appropriate to inform other third parties about
the personal information security breach such as the police, professional
bodies, the Privacy Commissioner or other regulators or professional
bodies.
(a) Deciding whether to notify affected individuals
In notifying affected individuals, a key consideration is whether
notification is necessary in order to avoid or mitigate serious harm to an
individual whose personal information has been inappropriately accessed,
collected, used or disclosed.
Agencies and organisations should consider the following factors when
deciding whether to notify:
- What is the risk of serious harm to the individual as determined by
step 2?
- What is the ability of the individual to avoid or mitigate possible
harm if notified of a breach (in addition to steps taken by the agency or
organisation)? For example, would an individual be able to have a new
bank account number issued to avoid potential financial harm resulting
from a breach? Would steps such as monitoring bank statements or
exercising greater vigilance over their credit reporting records assist
in mitigating risks of financial or credit fraud?
- Even if the individual would not be able to take steps to fix the
situation, is the information that has been compromised very sensitive or
likely to cause humiliation or embarrassment for the individual?
- What are the legal and contractual obligations to notify and what are
the consequences, of notification?
- What are the consequences of failing to notify affected individuals? If
individuals subsequently find out about the breach through the media for
example, what could be the associated loss of trust that the agency or
organisation sustains?
(b) Process of notification
At this stage, the organisation or agency should have as complete a set of
facts as possible and have completed the risk assessment in order to
determine whether to notify individuals. The following tables set out some
of the considerations in the process of notification.
Sometimes the urgency or seriousness of the breach dictates that
notification should happen immediately, before having all the necessary
facts.
When to notify:
|
In general
|
Other considerations
|
Notification of individuals affected by
the breach should occur as soon as reasonably possible.
|
If law enforcement authorities are
involved, check with those authorities whether notification should be
delayed to ensure that the investigation is not compromised.
Delaying the disclosure of details about a breach of security or
information systems may also be appropriate until that system has
been repaired and tested or the breach contained in some other way.
|
How to notify:
|
In general
|
Other considerations
|
The preferred method of notification is
direct either by phone, letter, email or in person -
to affected individuals.
Indirect notification, either by website information, posted
notices, media, should generallyonly occur
where direct notification could cause further harm, is prohibitive in
cost or the contact information for affected individuals is not
known.
|
Preferably notification should
'stand-alone' and should not be 'bundled' with other material
unrelated to the breach, as it may confuse recipients and affect the
impact of the breach notification.
Using multiple methods of notification in certain cases may be
appropriate.
Agencies and organisations should also consider whether the method
and content of notification might increase the risk of harm, such as
by alerting the person who stole the laptop of the value of the
information on the computer if it would not otherwise be apparent.
To avoid being confused with phishing emails, email notifications
may require special care. For example, only communicate basic
information about the breach, leaving more detailed advice to other
forms of communication.
|
Who should notify:
|
In general
|
Other considerations
|
Typically, the agency or organisation
that has a direct relationship with the customer, client or employee
should notify the affected individuals.
This includes where a breach may have involved handling of
personal information by a third party service provider, contractor or
related body corporate.
|
Joint and third party relationships can
raise complex issues - the breach may occur at a retail merchant but
involve credit card details from numerous financial institutions or
the card promoter may not be the card issuer (for example, many
airlines, department stores and other retailers have credit cards
that display their brand, though the cards are issued by a bank or
credit card company).
Each situation will vary and organisations and agencies will have
to consider what is best on a case by case basis. However some
relevant considerations might be:
- Where did the breach occur?
- Who does the individual identify as their "relationship"
manager?
- Does the agency or organisation have contact details for the
individuals? Are they able to obtain them easily? Or could they
draft and sign off the notification, for the lead organisation to
send?
- Is trust important to organisation's or agency's activities?
|
Who should be notified?
|
In general
|
Other Considerations
|
Generally it should be the individual/s
who are affected. However, in some cases it may be appropriate to
notify the individual's guardian or authorised representative on
their behalf.
|
There may be circumstances where carers
or authorised representatives should be notified as well as, or
instead of, the individual.
Where appropriate, clinical judgement may be required where
notification may exacerbate health conditions, such as acute
paranoia.
|
(c) What should be included in the notification?
The content of notifications will vary depending on the particular breach
and the method of notification chosen. In general, the information in the
notice should help the individual to reduce or prevent the harm that could be
caused by the breach. Notifications should include the types of information
detailed in the table below.
Incident Description
|
Information about the incident and its
timing in general terms. The notice should not include information
that would reveal specific system vulnerabilities.
|
Type of personal information
involved
|
A description of the personal
information involved in the breach.
Be careful not to include personal information in the notification
to avoid possible further unauthorised disclosure.
|
Response to the breach
|
A general account of what the agency or
organisation has done to control or reduce the harm, and proposed
future steps that are planned.
|
Assistance offered to affected
individuals
|
What the agency or organisation will do
to assist individuals and what steps the individual can take to avoid
or reduce the risk of harm or to further protect themselves.
Possible actions include arranging for credit monitoring or other
fraud prevention tools, providing information on how to change a
government issued identification number, personal health card or
driver licence number.
|
Other information
sources
|
Sources of information designed to
assist individuals in protecting against identity theft or
interferences with privacy.
For example, guidance on the Office of the Privacy Commissioner's
website http://www.privacy.gov.au/ and
the Attorney-General's Department website at http://www.ag.gov.au/www/agd/agd.nsf/page/Crimeprevention_Identitysecurity
|
Agency/ Organisation contact
details
|
Contact information of areas within the
agency or organisation that can answer questions, provide further
information or address specific privacy concerns.
Where it is decided that a third party will notify of the breach,
a clear explanation should be given as to how that third party fits
into the process and who the individual should contact should they
have further questions.
|
Whether breach notified to
regulator or other external contact(s)
|
Indicate whether the agency or
organisation has notified the Office of the Privacy Commissioner or
other parties listed in the table 4(d).
|
Legal implications
|
The precise wording of the notice may
have legal implications, so should be checked accordingly. This
could include secrecy obligations that apply to agencies.
|
How individuals can lodge a
complaint
|
With the agency or
organisation
Provide information on internal dispute resolution processes and
how the individual can make a complaint to the agency or organisation
or industry complaint handling bodies.
With the Privacy Commissioner
Explain that if individuals are not satisfied with the response by
the agency or organisation resolve the issue, that they can make a
complaint to the Office of the Privacy Commissioner.
Include the contact information for the Office of the Privacy
Commissioner:

(d) Others to Contact
In general, notifying the Office, other authorities or regulators should
not be a substitute for notifying individuals. However, in some circumstances
it may be appropriate to notify these third parties.
Privacy Commissioner
|
Agencies and organisations may decide
to report significant personal information security breaches to the
Privacy Commissioner. The potential benefits of notifying the
Privacy Commissioner, together with what the Privacy Commissioner can
and can do about a notification, are set out in Section 8 of this
guide.
The following factors should be considered in deciding whether to
report a breach to the Privacy Commissioner:
- any applicable legislation that may require notification
- the type of the personal information involved and whether there
is a real risk of serious harm arising from the breach, including
non-monetary losses
- whether a large number of people were affected by the breach
- whether the information was fully recovered without further
disclosure
- whether the individuals affected have been notified and
- if there is a reasonable expectation that the Office may
receive complaints or inquiries about the breach.
|
Police
|
If theft or other crime is suspected.
The Australian Federal Police should also be contacted if a
compromise to national security is suspected.
|
Insurers or others
|
If required by contractual
obligations.
|
Credit card companies,
financial institutions or credit reporting agencies
|
If their assistance is necessary for
contacting individuals or assisting with mitigating harm.
|
Professional or other
regulatory bodies
|
If professional or regulatory standards
require notification of these bodies. For example, other regulatory
bodies, such as the Australian Securities and Investments Commission,
the Australian Competition and Consumer Commission, the Australian
Communications and Media Authority and the Australian Prudential
Regulatory Authority have their own requirements in the event of a
breach.
|
Other internal or external
parties not already notified
|
Agencies and organisations should
consider the potential impact that the breach and notification to
individuals may have on third parties and take actions accordingly.
For example, third parties may be affected if individuals cancel
their credit cards or if financial institutions issue new cards.
Consider:
- third party contractors or other parties who may be impacted;
- internal business units not previously advised of the breach,
(e.g. communications and media relations, senior management); or
- union or other employee representatives
|
Agencies that have a direct
relationship with the information lost / stolen
|
Agencies and organisations should
consider whether an incident compromises Commonwealth agency
identifiers such as Tax File Numbers (TFNs) or Medicare numbers.
Notifying agencies such as the Australian Taxation Office for TFNs or
Medicare Australia for Medicare card numbers may enable those
agencies to provide appropriate information and assistance to
affected individuals, and to take steps to protect the integrity of
identifiers that may be used in identity theft or other fraud.
|
An example of notification of affected individuals
A bank customer, Margaret, receives mail from her bank. When she opens
the envelope she notices that correspondence intended for another customer -
Diego - has been included in the same envelope. The correspondence includes
Diego's name, address and account details.
Margaret contacts the bank to report the incident. The bank asks that
she return the mail intended for Diego to them and the Bank then contacts
Diego to notify him about what has occurred.
The bank contacts Diego by phone to notify him about the breach,
apologises to him and advises that it will be investigating the matter to
determine how the incident occurred and how to prevent it from occurring
again. The bank also offers to restore the security of Diego's customer
information by closing his existing account and opening a new account. In
addition, the bank agrees to discuss with Diego any further action he
considers should be taken to resolve the matter to his satisfaction and
provides a contact name and number that Diego can use for any further
enquiries.
The bank undertakes an investigation of the matter which includes getting
reports from the mailing house it uses to generate and despatch customer
correspondence. While the mailing house had a number of compliance measures
in place to manage the process flow it appears that an isolated error on one
production line meant that two customer statements were included in one
envelope.
Following its assessment of the breach, the bank is satisfied that this is
an isolated incident. However, it also reviews the compliance measures the
mailing house has in place to ensure they are sufficient to protect customer
information from unintentional disclosure through production errors. The
bank writes to Diego and informs him of the outcome of its investigation.
An example of notification of affected individuals and Privacy
Commissioner
A memory stick containing the employee records of 200 employees of a
Commonwealth Government department goes missing. Extensive searches fail to
locate the whereabouts of the memory stick. The information contained in the
employee records includes the names, salary information, TFNs, home
addresses, phone numbers, birth dates and in some cases health information
(including disability information) of current staff. Information on the
memory stick is not encrypted.
Due to the sensitivity of the unencrypted information - not only the
extent and variety of the information, but also the existence of health and
disability information in the records - the Department decides to notify
employees of the breach. Anticipating that individuals may, at some point,
complain, it also notifies the Privacy Commissioner of the breach and
explains what steps it is taking to resolve the situation.
A senior staff member emails staff to notify them of the breach. In the
notification she offers staff an apology for the breach, explains what types
of information were breached, notes that the Privacy Commissioner has been
informed of the breach, and explains what steps have been put in place to
prevent this type of a breach occurring in the future. In the notification to
staff, the senior staff member also provides staff with details about how
they can have a new TFN issued and informs staff that if they are unhappy
with the steps the agency has taken they can make a complaint to the Office
of the Privacy Commissioner.
An example of notification of affected individuals, Privacy
Commissioner and police
A ticket retailer sells concert tickets at various outlets and online.
Online purchases are done on a secure site using a credit card. During a
routine security check, the ticket retailer discovers through the use of
intrusion detection software that the database connected to its secure site
has been compromised and customer information stolen. The ticket retailer
takes steps to contain the breach and then, based on its belief that criminal
activity has been involved, contacts the police.
The police investigate, during which time they ask the ticket retailer not
to release any information about the breach. The ticket retailer uses this
period to engage a technology security firm to enhance the security of its
online purchasing systems.
Once satisfied that notification will not compromise police
investigations, the retailer notifies the Privacy Commissioner of the breach
and then emails affected ticket purchasers. In notifying the ticket
purchasers, the retailer explains exactly what happened and when; that the
police have been investigating; and that the Privacy Commissioner has been
notified. It also suggests that affected ticket purchasers monitor their
credit card accounts and contact their financial institution if they have any
concerns.
An example of notification of affected individuals, Privacy
Commissioner and police
A small business that rents out household items keeps credit reports of
rental applicants on site in hard copy. These reports have been stamped
"out of date".
A box of the reports goes missing. The small business is unable to locate
the reports and fears they have been stolen. The credit reports include the
name, current or last known address and two previous addresses, drivers
licence number, date of birth and employer details.
Based on the belief that theft may be involved, the small business alerts
the police.
Due to the types of information that have been lost (which in combination
may create a serious risk of identity theft) the small business judges that
the breach is serious enough to warrant notification of rental applicants and
the Privacy Commissioner.
The small business knows that the credit reports relate to applicants from
the last two months. It decides to notify individuals who have applied for
rentals during this period that information contained in their credit report
may have been compromised. In the notification the small business advises
individuals to monitor their credit reports for suspicious activity and
commits to more secure storage of credit reports in the future.
To meet the commitment to store reports more securely, the small business
undertakes to review physical security measures, including by storing reports
in a locked cabinet and ensures that staff understand the importance of
handling the reports appropriately.
An example of no notification
In contravention of policy, a staff member at a Commonwealth Government
department takes a memory stick out of the office so that he can work on at
home. At some point between leaving work and arriving at home, the staff
member loses the memory stick. The staff member reports it missing the next
day.
Despite the assistance of the transport authority, the Department is
unable to locate the memory stick. Following a preliminary assessment of the
breach, the Department undertakes to evaluate the risks associated with the
loss of the memory stick.
The Department first assesses what (if any) personal information may have
been lost with the memory stick. While the memory stick did not contain
client records, it did contain the names, phone numbers and email addresses
of about 120 external stakeholders contributing to a project lead by the
Department, along with email correspondence from these stakeholders.
Further evaluation of the risks associated with the loss of the memory
stick reveal that data held on the stick is protected by high level
encryption technology. The Department consults with its IT team to confirm
that the encryption on the memory stick is adequately secure and following
confirmation by the IT team, decides that notification of individuals whose
personal information was held on the memory stick is not necessary.
An example of no notification
A pathologist receives a phone call from a GP, Dr Angel, with whom he has
a professional relationship. Doctor Angel advises the pathologist that she
has just received a fax from the pathologist's office disclosing test result
for an individual that is not the her patient. When the pathologist checks
his records, he discovers that the test results were intended for a different
GP.
The pathologist asks Dr Angel to destroy the test results and considers
whether notification of the patient is warranted.
The pathologist recognises that the GP is bound by ethical duties and is
familiar with principles of confidentiality and privacy. Accordingly, the
pathologist is confident that Dr Angel can be relied upon not to mishandle
the information contained in the test results and the disclosure is unlikely
to pose a serious risk to the privacy of the individual.
The pathologist decides not to notify but does review his practices to
avoid a similar breach occurring in the future. To reduce the chance of such
mistakes happening again, the specialist puts in place a series of steps,
including ensuring that administrative staff are counselled to exercise care
in checking that fax numbers are accurate. The specialist also considers
taking the step of routinely phoning recipients to put them on notice that
results are being faxed. This reduces the risk that any fax, whether
misdirected or not, will be left unattended on the machine for long periods
of time, and may allow the intended recipient to let the sender know if it is
not received.
STEP 4: Prevent future breaches
Once the immediate steps are taken to mitigate the risks associated with
the breach, agencies and organisations need to take the time to investigate
the cause of the breach and consider whether to either evaluate the existing
prevention plan or develop one.
A prevention plan should suggest actions which are proportionate to the
significance of the breach and whether it was a systemic breach or an
isolated instance.
This plan may include the following:
- a security audit of both physical and technical security
- a review of policies and procedures and any changes to reflect the
lessons learned from the investigation and regularly after that (for
example, security, record retention and collection policies)
- a review of employee selection and training practices and
- a review of service delivery partners (e.g. dealers and retailers).
The plan may include a requirement for an audit at the end of the process
to ensure that the prevention plan has been fully implemented.
Some suggestions for being prepared to respond to a breach are:
- Develop a breach response plan: while the aim should be to prevent
breaches, having a breach response plan may assist in ensuring a quick
response to breaches, and greater potential for mitigating harm from the
breach.
A plan could set out contact details for appropriate staff that should be
notified; clarify the roles and responsibilities of staff; and document
processes for the agency or organisation to contain breaches, coordinate
investigations and breach notifications and cooperate with external
investigations.
- Depending on the size of the agency or organisation, a management group
responsible for responding to personal information breaches could be
established, with representatives from relevant areas that may be needed
to investigate an incident, conduct risk assessments and make appropriate
decisions (e.g. privacy, senior management, IT, public affairs, legal).
The group could convene periodically to review the response plan, discuss
new risks and practices, or consider incidents that have occurred in
other agencies or organisations.
- Include information in the agency or organisation's privacy policy
about how it respond to breaches. This could include letting individuals
know how they are likely to be notified in the event of a breach and
whether the agency or organisation would ask them to verify any contact
details or other information.
This would make clear to individuals how their personal contact
information is used in the event of a breach, and may also assist
individuals to avoid 'phishing' scam emails involving fake breach
notifications and asking recipients to verify their account details,
passwords and other personal information.
Tips for preventing future breaches
Some of the measures that have resulted from real-life personal
information security breaches are:
- the creation of a senior position in the agency or organisation with
specific responsibility for data security
- a ban on bulk transfers of data onto removable media without adequate
security protection (such as encryption)
- disabling the download function on computers in use across the agency
or organisation to prevent the download of data onto removable media
- ensure hard drives and other storage media are erased before being
disposed
- use secure couriers and appropriate tamper proof packaging in the
transport of bulk data and
- a ban on the removal of unencrypted laptops and other portable devices
from government buildings.
Technological advances allow increasingly larger amounts of information to
be stored on increasingly smaller devices. This creates a greater risk of
personal information security breaches due to the size and portability of
these devices, which can be lost or misplaced more easily when taken outside
of the office. There is also a risk of theft because of the value of the
devices themselves (regardless of the information they contain).
Preventative steps that agencies and organisations can take include
conducting risk assessments to determine:
- whether and in what circumstances (and by which staff), personal
information is permitted to be removed from the Office, whether it is
removed in electronic form on disks, USB storage devices, laptops and
other portable devices or in physical files and
- whether their stored data, both in the office and when removed from the
office, requires encryption security.
Responding to a large scale
data breach: An illustration of how to work through the Four Key
Steps
A health insurer discovers that a backup tape containing customer
details and other data has been lost. The information on the tape
was not encrypted. The insurer creates two copies of each backup
tape. One tape is stored on-site, the other tape is stored securely
off-site. The lost backup tape was the copy stored on-site and
included data collected over the previous month.
Step 1 - Containing the breach and the preliminary
assessment
The Chief Executive Officer nominates the Risk & Compliance
Manager to lead an investigation. The Risk Manager's initial
assessment suggests that the tapes were lost when the insurer's IT
department moved some records between floors.
The Risk Manager interviews the staff involved in moving the
records, reviews the relocation plan and arranges for the building to
be searched. Despite these efforts, the tape cannot be found.
The Risk Manager moves onto assessing the breach. She thinks
that the breach was most likely the result of poor practices and
sloppy handling. However, while there is no evidence that the tape
was stolen, theft cannot be ruled out. The type of information that
has been lost and how it could be used is an important part of the
risk assessment.
Step 2 - Evaluate the risks associated with the
breach
The evaluation shows that the information on the tapes falls into
3 main groups:
|
Group
1
|
Group 2
|
Group 3
|
Type of
Information
|
Enquiry information collected
via the website to provide quotes.
Only included state, date of birth and gender and is
retained for statistical marketing purposes.
|
Application
information, including full name, address, contact details,
and date of birth. Also includes Medicare card number, and
credit card details.
|
Claim information,
including full name, member number, contact details, and
clinical information about the treatment being claimed
|
Identity apparent or
ascertainable
|
No - the information is
aggregated statistical data only.
|
Yes
|
Yes
|
Sensitivity
|
None
|
Substantial
identifying information, Medicare card number and financial
details.
|
Substantial
identifying information, as well as information about the
individual's health condition.
|
How could the
information be used?
|
The information is likely to be
of little or no use other than for statistical purposes.
|
The information
could be used for identity theft and financial fraud.
Lesser possibility that it could be used to attempt fraud
against the Medicare and PBS systems.
|
The information
could be used for identity theft, as well as being
potentially embarrassing or stigmatising to the individual.
|
Source
|
Probably
unintentional, accidental loss. But theft is also a
possibility. As the source is unclear, and given the
sensitivity of much of the information, insurers decide to
assume a worst case scenario.
|
Severity
|
Information was not
encrypted or recovered. The large number of records
involved and the sensitivity of the much of the records
(health and financial information, as well as identifying
information), make this a serious breach.
|
A real risk of serious
harm?
|
No
|
Yes - the
information could be used to cause serious harm to
individuals - this could include identity theft, financial
fraud, and fraud against the Medicare and PBS systems.
Possibly health fraud.
|
Yes - if misused, the
identification information could be used for identity
theft.
Serious harm could also arise from misuse of the health
information, including stigma, embarrassment, discrimination
or disadvantage, or in extreme cases blackmail.
|
Current contact details
held?
|
No
|
Yes from current
member list and external sources.
|
Yes from current member list
and external sources.
|
The evaluation shows that a real risk of serious harm arises for
Group 2 and 3 individuals and that the information in Group 1 is not
personal information.
Step 3 - Consider Notification
The evaluation indicates that individuals in Groups 2 and 3 should
be notified about the breach, about there is a real risk of serious
harm to their interests. If notified, individuals could take steps
to mitigate the risks of identity theft and financial fraud. This
could include changing credit card details or monitoring their credit
report. While there may be limited steps that can be taken to
mitigate the risks of their health information being mishandled,
individuals should still be informed given the heightened
sensitivities of this information.
The Risk Manager also considered whether notification would cause
harm by leading to unfounded concern or alarm.
Taking all these factors and the evaluation into account, it is
decided that individuals in Groups 2 and 3 should be notified.
Separate letters are drawn up for each group, outlining the general
types of information that are affected.
The Risk Manager also arranges for the notification letters to
include:
- a general description of the type of information that has been
lost for each group
- what individuals can do to mitigate the harm caused by the
breach and
- who they can call to get further information or assistance.
For example, the notification for individuals in Group 2 tells
them that the information they provided on their application form may
have been compromised, including their Medicare number and credit
card details. If an individual is concerned about either, they are
advised to contact Medicare Australia or their financial institution
so as to change their registration and account details. Group 3
individuals are told that a record containing their claims
information has been lost, including the clinical details held on
their file.
Both letters explain that there is no evidence of theft, and that
the company is notifying the individuals as a precautionary measure
only.
The notifications also include contact details for the insurer's
customer care area and the Office of the Privacy Commissioner, and
suggests that individuals should check their credit card account
statements and credit reports for any unusual activity.
The Risk Manager also notes that some claimants had an authorised
representative acting for them. These records will be separately
assessed to determine whether notification should be made to the
authorised representative rather than the member.
Staff in the insurer's customer care area are briefed about the
breach and given instructions about how to help customers responding
to a notification.
While the insurer does not have to notify the Privacy
Commissioner, it decides to do so given the large number of
individuals affected and sensitive nature of the information. It
explains to the Privacy Commissioner what steps it has taken to
address the breach.
Step 4 - Preventing Future Breaches
Once immediate steps have been taken to respond to the breach, the
Chief Information Officer carries out an audit of the security
policies for storage and transfer of backup tapes and reviews the
access of staff in the area. The CIO also makes some amendments to
the compliance program to ensure non-compliance with IT Security
policies will be detected and reported in the future.

8. The Role of the Office of the Privacy Commissioner
The Office, on behalf of the Privacy Commissioner, has the function of
investigating possible breaches of the Privacy Act. It also has the
function of providing advice to agencies and organisations on any matter
relevant to the operation of the Privacy Act. While the Office has no
formal role in relation to breach notification, it may provide general advice
on how to respond to a personal information security breach.
Step 3(d) of the guide provides guidance on when it may be appropriate to
notify the Office of a personal information breach. Consistent with its
statutory functions, the Office may consider whether it needs to investigate
the conduct.
A personal information breach may constitute a breach of information
security obligations under the IPPs or NPPs, and in that circumstance it will
be an interference with an individual's privacy.[13] However, the Office cannot make a decision on
whether there has been a breach of the Act until it has conducted an
investigation.
If an individual thinks an agency or organisation has interfered with his
or her privacy, and they have been unable to resolve the matter directly with
the agency or organisation, they can complain to the Privacy Commissioner.
The Office may investigate and may attempt to resolve the matter by
conciliation between the parties.
The Privacy Act does not specify penalties for breaches of the IPPs or
NPPs, though deliberate contravention of some of the credit reporting
provisions in Part IIIA of the Privacy Act does carry penalties. The
Privacy Commissioner may make determinations requiring the payment of
compensation for damages or other remedies, such as the provision of access
or the issuance of an apology. These determinations can be enforced by the
Federal Court or Federal Magistrates Court.
The Office also has the power to initiate an investigation on its own
motion in appropriate circumstances without first receiving a complaint.
Agencies should also be aware that, under s 27(1)(j) of the Privacy Act,
the Privacy Commissioner can inform the Cabinet Secretary, as the Minister
responsible for the Privacy Act, of action that needs to be taken by an
agency in order to achieve compliance by the agency with the IPPs.
The Office conducts its investigations in private, and in general will not
publicise details of its inquiries. However, consistent with its roles of
education and enforcement, in some circumstances the Commissioner may
publicise information about the information management practices of an agency
or organisation.
8.1 Reporting a personal information security breach to the
Office
The Privacy Act does not specifically require agencies and organisations
to report personal information security breaches to the Privacy
Commissioner. However, agencies and organisations may choose to notify the
Office of a personal information security breach where the circumstances
indicate that it is appropriate to do so, as set out in Step 3(d). The
following are some potential benefits from notifying the Office of a personal
information security breach:
- An agency or organisation's decision to notify the Office on its own
initiative may be viewed by the public as a positive action. It tells
clients and the public that the agency or organisation views the
protection of personal information as an important and serious matter.
This may enhance public/client confidence in the agency or organisation.
- It can assist the Office in responding to inquiries made by the public
and managing any complaints that may be received as a result of the
breach. If the agency or organisation provide the Office with details of
the matter, and the action taken to address it, and prevent future
occurrences, then it may be that any complaints received can be dealt
with more quickly based on that information. In those circumstances,
consideration will need to be given to whether an individual complainant
can demonstrate that they have suffered loss or damage, and whether some
additional resolution is required, or alternatively, the Office may
consider that the steps taken have adequately dealt with the matter.
It is important to note
that reporting a breach does not preclude the Office from receiving
complaints and conducting an investigation of the incident (whether in
response to a complaint or of its own motion).
If the agency or organisation decide to report a personal information
security breach to the Office, the following provides an indication of what
the Office can and can't do:
What the Office can do:
- Provide general information about obligations under the Privacy Act,
factors to consider in responding to a personal information security
breach and steps to take to prevent similar future incidents.
- Respond to community enquiries about the breach and explain possible
steps individuals can take to protect their personal information.
What the Office cannot do:
- Provide detailed advice about how to respond to a breach or approve a
particular proposed course of action. Agencies and organisations will
need to seek their own legal or other specialist advice.
- Agree not to investigate (either using the Commissioner's 'own motion
investigation' powers, or if a complaint is made to the Office) if the
Office is notified of a breach.
When the Office receives a complaint about an alleged breach of the Act,
in most cases, the Office must investigate. As set out above, the Office
may also investigate an act or practice in the absence of a complaint, on its
'own motion'. The Office uses risk assessment criteria to determine whether
to investigate a matter on its own motion. These criteria include:
- whether a large number of people have been, or are likely to be
affected, and the consequences for those individuals
- the sensitivity of the personal information involved
- the progress of an agency or organisation's own investigation into the
matter
- the likelihood that the acts or practices involve systemic or
widespread interferences with privacy;
- what actions have been taken to minimise the harm to individuals
arising from the breach, such as notifying them and/or offering to
re-secure their information and
- whether another body, such as the police, are investigating.
These factors are similar to those included in the risk assessment
criteria for responding to a personal information security breach.
8.2 What to put in a notification to the Office
Any notice provided to the Office should contain similar content to that
provided to individuals. It should not include personal information about
the affect individuals. It may be appropriate to tell the Office:
- a description of the breach
- the type of personal information
- what response the agency or organisation has made to the breach
- what assistance has been offered to affected individuals
- who is the contact person
- whether the breach notified has to other external contact(s).

A record-keeper who has possession or control of a record that contains
personal information shall ensure:
(a) that the record is protected, by such security safeguards as it is
reasonable in the circumstances to take, against loss, against unauthorised
access, use, modification or disclosure, and against other misuse; and
(b) that if it is necessary for the record to be given to a person in
connection with the provision of a service to the record-keeper, everything
reasonable within the power of the record-keeper is done to prevent
unauthorised use or disclosure of information contained in the record.

[3] IPP4 and NPP4,
require agencies and organisations, respectively, to protect information they
hold from misuse and loss and from unauthorised access, modification or
disclosure.
[4] An organisation, as
defined under the Privacy Act 1988, is
- (a) an individual, or;
- (b) a body corporate or;
- (c) a partnership or;
- (d) any other unincorporated association or;
- (e) a trust;
that is not a small business operator, a registered political party, an
agency, a State or Territory authority or a prescribed instrumentality.
[5] For example,
organisations that are reporting entities for the purposes of the Anti
Money Laundering and Counter Terrorism Financing Act 2006 are required
to comply with the NPPs in terms of these activities, even if they are
otherwise exempt under the Privacy Act.
[6] Although the titles
for NPP 3, NPP 4 and NPP 9 all refer to 'data' (being the 'Data quality',
'Data security' and 'Transborder data flows' principles respectively), this
term tends not to be used in the substantive provisions of the Act. See
Privacy Act 1988 (Cth), Schedule 3. The NPPs are available at http://www.privacy.gov.au/publications/npps01.html.
[7] See the 'security
safeguards principle' in the Organisation for Economic Cooperation and
Development (OECD) Guidelines on the Protection of Privacy and
Transborder Flows of Personal Data (1980) available at http://www.oecd.org/document/18/0,2340,en_2649_34255_1815186_1_1_1_1,00.html.
The Privacy Act 1988 (Cth) was enacted to implement the OECD
guidelines in Australia, as recognised in the preamble to the Act.

[10] See the
Office's Guidelines to the Information Privacy Principles
(principles 4-7) for a brief overview of existing guidance on
security standards for agencies, available at http://www.privacy.gov.au/government/guidelines/index.html.
[11] Employee
Records (as defined in s6 of the Privacy Act) directly related to an
employment relationship of current or former employees are exempt from
coverage by the NPPs under s7B(3).
[12] See the
'openness principle' in the Organisation for Economic Cooperation and
Development (OECD) Guidelines on the Protection of Privacy and
Transborder Flows of Personal Data (1980), available at http://www.oecd.org/document/18/0,2340,en_2649_34255_1815186_1_1_1_1,00.html.
This principle is reflected in NPP 5 and IPP 2 in the Privacy Act
1988 (Cth).
