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.
Run the following commands to determine if there is a cron job scheduled to run the aide check.
# crontab -u root -l | grep aide # grep -r aide /etc/cron.* /etc/crontab
Ensure a cron job in compliance with site policy is returned.
Run the following command:
# crontab -u root -e
Add the following line to the crontab:
0 5 * * * /usr/sbin/aide --check
The checking in this recommendation occurs every day at 5am. Alter the frequency and time of the checks in compliance with site policy.
