SI-14(2): Non-persistence | Non-persistent Information

Control Text:

(a) [Selection: Refresh [Assignment: organization-defined information][Assignment: organization-defined frequency]; Generate [Assignment: organization-defined information] on demand]; and (b) Delete information when no longer needed.

Retaining information longer than is needed makes the information a potential target for advanced adversaries searching for high value assets to compromise through unauthorized disclosure, unauthorized modification, or exfiltration. For system-related information, unnecessary retention provides advanced adversaries information that can assist in their reconnaissance and lateral movement through the system.
