With less than three months until the General Data Protection Regulation 2016/279 (GDPR) comes into effect on 25 May 2018, the Article 29 Working Party (WP29) published revised guidelines on personal data breach notification (Guidelines). You may well remember our recent blog covering the Guidelines when the WP29 issued its initial guidance on 3 October 2017.
The revised Guidelines are largely similar, so in this blog, we provide a recap of the Guidelines regarding personal data breach notification requirements under GDPR.
Personal data breach
The WP29 has provided that a personal data breach – that is, a breach of security which could lead to loss, destruction, damage or unauthorised disclosure or access to personal data – can be categorised as follows:
- Confidentiality breach: unauthorised or accidental disclosure or access to personal data.
- Integrity breach: unauthorised or accidental alteration of personal data.
- Availability breach: accidental or unauthorised loss of access or destruction of personal data.
