Implement Periodic Execution of Integrity Checking
By default, AIDE does not install itself for periodic execution.
Implement checking with whatever frequency is required by your security policy.
A once-daily check may be suitable for many environments. For example, to
implement a daily execution of AIDE at 4:05am, add the following line to /etc/crontab:
05 4 * * * root /usr/sbin/aide –check
AIDE output may be an indication of an attack against your system, or it may
be the result of something innocuous such as an administrator’s configuration
change or a software update.
