Ensure filesystem integrity is regularly checked

SrednjaNivo 1Automatskafreebsd

Opis

Periodic checking of the filesystem integrity is needed to detect changes to the filesystem. Periodic file checking allows the system administrator to determine on a regular basis if critical files have been changed in an unauthorized fashion. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.
