Implementation guidance The header page and this section, up to and including Disclaimer, must be removed from the final version of the document. For more details on replacing the logo, yellow highlighted text and certain generic terms, see the Completion Instructions document.

Purpose of this document This procedure sets out how the organization acting as a controller will meet, as a minimum, the notification requirements of relevant privacy legislation (assumed to be the GDPR) in the event of a breach of personal data.

Areas of the standard addressed This document addresses the following sections of the ISO/IEC 27001 standard: •

A.5 Organizational controls o A.5.24 Information security incident management planning and preparation o A.5.26 Response to information security incidents o A.5.34 Privacy and protection of PII

General guidance This document may be used as a template for compliance with the notification requirements for a range of privacy legislation that may apply to your organization.

Privacy legislation is usually specific in terms of the information that must be provided to the regulator if a breach happens and the conditions that must be met if notification to data subjects is required. It is important to understand these requirements and be able to take considered decisions regarding notification that not only comply with the legislation, but also meet the organization’s business and ethical needs and aspirations.

Note that this procedure applies mainly to the situation where the organization is a controller for the personal data involved. If the organization is a processor, the main obligations are to inform the data controller so that they can fulfil their obligations regarding breach notification, and this situation is also covered in this procedure.

Personal Data Breach Notification Procedure [Insert classification]

1 Introduction This procedure is intended to be used when an incident of some kind has occurred that has resulted in, or is believed to have resulted in, a loss of personal data (also referred to as PII, personally identifiable information). This document should be used in conjunction with the Information Security Incident Response Procedure which describes the overall process of reacting to an incident affecting the information security of [Organization Name].

This document acts as a general guide to the breach notification process and must be used in the context of the specific privacy laws that apply to [Organization Name].

It is a requirement of many privacy laws that incidents affecting personal data that are likely to result in a risk to the rights and freedoms of data subjects must be reported to the appropriate data protection supervisory authority by the controller without undue delay and where feasible, within a specific timeframe of becoming aware of it. If the timeframe target is not met, reasons for the delay must be given.

In the situation where we are acting as a processor, there is a general obligation to inform the controller(s) of the personal data about the breach without undue delay.

Where an incident affects personal data for which we are a controller, a decision must be taken regarding the extent, timing and content of communication with data subjects. In the case of many privacy laws the communication must happen without undue delay if the breach is likely to result in a high risk to the data subject.

The actions set out in this document should be used only as guidance when responding to an incident. The exact nature of an incident and its impact cannot be predicted with any degree of certainty and so it is important that a good degree of common sense is used when deciding what to do. However, it is intended that the steps set out here will prove useful in ensuring that our obligations under the applicable legislation are fulfilled.

This procedure should be considered in conjunction with the following related documents: • • • •

2 Personal data breach notification procedure Once it has been decided that a breach of personal data has occurred, there are three parties who may be required to be informed. These are: • • •

The controller(s) of the personal data The supervisory authority (or similar regulatory body, see Table 2) The data subjects affected

It is not a foregone conclusion that the breach must be notified; this depends upon an assessment of the risk that the breach represents. The following sections describe how this decision must be taken and what to do if notification is required.

2.1 Controller(s) of the personal data Where [Organization Name] is acting as a processor of personal data on behalf of one or more controllers, there is an obligation to inform each controller about the breach without undue delay. It will then be up to the controller to decide whether it needs to be reported, and to take subsequent actions.

In order to allow the controller to meet the requirements of the applicable legislation, [Organization Name] will need to provide the following information to them: • • • • • • • • • • • •

The date and time that the breach was discovered The date and time that the breach is believed to have occurred The data items included e.g. name, address, bank details, biometrics The volume of data involved The number of data subjects affected The nature of the breach, for example theft, accidental destruction Whether the personal data was encrypted If encrypted, the strength of the encryption used To what extent the data was pseudonymised (i.e. whether living individuals can reasonably be identified from the data) The actions that have been taken to manage the impact of the breach Contact details of the person handling the breach within our organization Any other factors that are deemed to be relevant

Where more than one controller is involved, care must be taken to ensure that only information about each individual controller’s personal data is provided.

2.2 The supervisory authority Where [Organization Name] is the controller of the personal data involved, the relevant supervisory authority (or similar regulatory body, see Table 2) may need to be informed. The main supervisory authority for [Organization Name] is as follows:

NAME WEBSITE ADDRESS TELEPHONE FAX EMAIL Table 1: Supervisory authority contact details

Where [Organization Name] operates internationally, the details above are for the supervisory authority in the country of its main establishment or marketplace.

The following table shows the reporting requirements, regulatory authority and reporting timescales for the applicable privacy legislation. [Adjust the contents of the table according to the countries and states in which your organization operates] Title

Reporting requirements

Report to

California Consumer Privacy Act (CCPA)

Under the CCPA, if a business experiences a data breach that involves the unauthorized access and exfiltration, theft, or disclosure of personal information, and if the business determines that the breach is likely to result in a significant risk of harm to consumers, the business is required to provide notice to affected consumers.

VCDPA requires businesses to implement reasonable security measures to protect personal data. In the event of a data breach that is likely to result in harm to consumers, the VCDPA generally requires businesses to notify the Virginia Attorney General within a reasonable time but no later than 45 days after discovering the breach.

Table 2 - Reporting details for applicable legislation

2.2.1 Deciding whether to notify the supervisory authority Privacy legislation may state that a personal data breach shall be notified to the supervisory authority unless the personal data breach is unlikely to result in a risk to the data subject.

This requires that the organization assess the level of risk before deciding whether to notify.

Factors to be considered as part of this risk assessment should include: • • • • • • • •

Whether the personal data was encrypted If encrypted, the strength of the encryption used To what extent the data was pseudonymised (i.e. whether living individuals can reasonably be identified from the data) The data items included e.g. name, address, bank details, biometrics The volume of data involved The number of data subjects affected The nature of the breach e.g. theft, accidental destruction Any other factors that are deemed to be relevant

Parties involved in this risk assessment may include representatives from the following areas, depending on the nature and circumstances of the personal data breach:

Version 1

Personal Data Breach Notification Procedure [Insert classification] • • • • • • • •

Senior management Business area(s) Technology Information security Legal Data protection officer External consultants Others

The risk assessment method, its reasoning and its conclusions should be fully documented and signed off by top management. The result of the risk assessment should include one of the following conclusions: • • •

The personal data breach does not require notification The personal data breach requires notification to the supervisory authority only The personal data breach requires notification both to the supervisory authority and to the affected data subjects

These conclusions may be subject to change based on feedback from the supervisory authority and further information that is discovered as part of the ongoing investigation of the breach.

2.2.2 How to notify the supervisory authority If it is decided to notify the supervisory authority, this should be done without undue delay and, where feasible, not later than the applicable timeframe after having become aware of it. If there are legitimate reasons for not having given the notification within the required timescale, these reasons must be given as part of the notification.

The notification should be given via appropriate secure means to the body listed in Table 1, using the form Personal Data Breach Notification Form as a template.

The following information must be given as part of the notification: • • • • •

The nature of the personal data breach, including, where possible: o Categories and approximate number of data subjects concerned o Categories and approximate number of personal data records concerned Name and contact details of the data protection officer or other contact point where more information may be obtained A description of the likely consequences of the personal data breach A description of the measures taken or proposed to be taken to address the personal data breach including, where appropriate, measures to mitigate its possible adverse effects If the notification falls outside of the required window, the reasons why it was not submitted earlier

Personal Data Breach Notification Procedure [Insert classification] Written confirmation should be obtained from the supervisory authority that the personal data breach notification has been received, including the date and time at which it was received. Where necessary, the legislation may allow the information to be provided in phases without undue further delay.

Documentation of the personal data breach, including its effects and the remedial action taken, will be produced as part of the Information Security Incident Response Procedure.

2.3 Data subjects Where [Organization Name] is the controller of the personal data involved, the affected data subjects may also need to be informed.

2.3.1 Deciding whether to notify data subjects Some privacy legislation states that a personal data breach shall be notified to the data subject when the personal data breach is likely to result in a high risk to the data subject.

Note the addition of the word “high” over and above the definition given previously.

The risk assessment carried out earlier in this procedure (section 2.2.1) will have determined whether the risk to the data subjects affected is judged to be sufficiently high to justify notification to them.

However, if measures have subsequently been taken to mitigate the high risk to the data subjects, so that it is no longer likely to happen, then communication to the data subjects may not be required.

Notification to affected data subjects may also not be mandated by privacy legislation where it would involve disproportionate effort. However, in this case a form of public communication should be used instead.

Again, this may change based on feedback from the supervisory authority and further information that is discovered as part of the ongoing investigation of the breach.

2.3.2 How to notify data subjects Once it has been decided that the breach justifies communication to the data subjects affected, this must be done without undue delay.

The communication to the affected data subjects should describe in clear and plain language the nature of the personal data breach and must also cover:

Name and contact details of the data protection officer or other contact point where more information may be obtained A description of the likely consequences of the personal data breach A description of the measures taken or proposed to be taken to address the personal data breach including, where appropriate, measures to mitigate its possible adverse effects

In addition to the above points, it may be appropriate to offer advice to the data subject regarding actions they may be able to take to reduce the risks associated with the personal data breach.

In most cases it will be appropriate to notify affected data subjects via letter or email or both in order to ensure that the message has been received and that they have an opportunity to take any action required.
