A breach notification rule binding public and private bodies.

- Breach notice, Reporting
- Audit expectation
- none
What it requires
- Notify the Data Protection Commissioner within 24 hours of the breach occurring: section 49(1) runs the period from the security breach itself, not from the moment you learn of it.
- Notify the affected data subject as soon as practicable of any security breach affecting their personal data.
- As a data processor, notify the data controller as soon as practicable of any security breach affecting personal data you process on its behalf.
- Treat every security breach affecting personal data as notifiable: the Act sets no risk threshold below which the duty falls away.
These lines are LexLint's reading of the law's text.

What it makes you log
Logging duty
Section 49 requires a controller to notify the Commissioner of a security breach within twenty-four hours, a processor to notify the controller and a controller or processor to notify the data subject. It is a duty to notify and names no documentation or register of breaches, so it is not a record duty. The record of processing activities is section 45 and accountability is section 50, neither cited by this row. The row imposes no log or record duty.

What this law does
Section 49(1) requires a data controller to notify the Data Protection Commissioner within twenty-four hours of any security breach affecting personal data processed, a period the Act runs from the breach itself rather than from the moment the controller becomes aware of it. Section 49(2) requires a data processor to notify the data controller, as soon as practicable, of any security breach affecting personal data processed on the controller's behalf.
Section 49(3) requires a data controller or data processor to notify the data subject, as soon as practicable, of any security breach affecting personal data processed. None of the three duties is qualified by a risk threshold: the Act attaches them to any security breach affecting personal data, not only to one likely to cause harm. Section 82(2)(b) lets the Minister make regulations on the notification of security breaches, so the detail may be prescribed later.
Section 1 leaves commencement to a statutory instrument appointed by the Minister. The Data Protection Act (Commencement) Order, 2021 brought the Act into operation on , which is the day these provisions began to bind.
