Fix Recommendation

Configure AIDE to notify designated personnel if baseline configurations are changed in an unauthorized manner. The file integrity tool must notify the system administrator when changes to the baseline configuration or anomalies in the operation of any security functions are discovered.

Add or modify the following line in the "/etc/default/aide" file:

SILENTREPORTS=no

Check Contents

Verify that Advanced Intrusion Detection Environment (AIDE) notifies the system administrator when anomalies in the operation of any security functions are discovered by using the following command:

$ grep -i '^\s*silentreports' /etc/default/aide
SILENTREPORTS=no

If "SILENTREPORTS" is set to "yes", is commented out, or is missing, this is a finding.
