GDPR compliance prefigures a process where data management, once established, is constantly
monitored to identify signs of violations, i.e., data breaches.
To this end, your organization must setup a well-suited monitoring environment and tools through which such incidents can be quickly detected and notified to security operators and data protection officer (if any).
This activity includes the identification, collection, storage and correlation of events capable to highlight data breaches and allow security operators to investigate them to accurately characterize their actual impact.
