A personal data breach occurs whenever a breach of security leads to the accidental or unlawful destruction, loss, alteration, unauthorised disclosure of, or access to, personal data. Following an incident, the controller of that data has a limited period in which to investigate, contain and mitigate the breach, assess any risk attaching to the breach, and make appropriate notifications.
Following the unauthorised access to personal data by a third party, in the context of a complex contractual arrangement, our client needed advice as to whether it held the role of data controller over the affected data, and what it should do to respond to the breach.
