Data Retention
Data Retention: Rules and controls governing how long data is kept and when it must be deleted. It should be documented, assigned to an owner, measured, and reviewed at defined intervals.
How it works and where it fits
Data Retention must be considered across the complete data lifecycle: creation, processing, transfer, storage, sharing, archiving, and deletion. Safeguards depend on sensitivity, legal obligations, business value, and potential harm. Copies, metadata, and derived information may carry the same or a different protection requirement.
Practical security relevance
In practice, this calls for classification, governed access, suitable encryption, and traceable retention periods. Data flows and storage locations should be inventoried across cloud services, backups, and test environments. Monitoring and loss prevention complement technical controls, but they do not replace data minimization or the secure deletion of information that is no longer required.
