Title
The operating system must employ automated mechanisms, per organization defined frequency, to detect the addition of unauthorized components/devices into the operating system. (Cat II impact)
Discussion
By default, AIDE does not install itself for periodic execution. Periodically running AIDE may reveal unexpected changes in installed files.
Check Content
To determine that periodic AIDE execution has been scheduled, run the following command: # grep aide /etc/crontab /etc/cron.*/* If there is no output, this is a finding.
Fix Text
AIDE should be executed on a periodic basis to check for changes. To implement a daily execution of AIDE at 4:05am using cron, add the following line to /etc/crontab: 05 4 * * * root /usr/sbin/aide --check AIDE can be executed periodically through other means; this is merely one example.
