Plan for a data breach
Write down what to do when personal data leaks, before it happens.
How to do it
Name who decides, how to stop the leak, and how to tell people. Report a breach to the supervisory authority by the GDPR deadline that start every reporting clock from one moment computes. Tell the people affected when the risk to them is high. Keep a log of every breach, even small ones, as log every breach with its decision says. For keeping evidence and handling the attack itself, see security incidents.
How to check
Once a year, run a practice breach with the plan. The team reaches the authority report step before its computed deadline.
