1.3.2 Ensure filesystem integrity is regularly checked

Information

Periodic checking of the filesystem integrity is needed to detect changes to the filesystem.

Rationale:

Periodic file checking allows the system administrator to determine on a regular basis if critical files have been changed in an unauthorized fashion.

Solution

Run the following command:

# crontab -u root -e

Add the following line to the crontab:

0 5 * * * /usr/sbin/aide --check

Additional Information:

The checking in this recommendation occurs every day at 5am. Alter the frequency and time of the checks in compliance with site policy.
