Fix Recommendation

Configure the audit system to generate an audit event for any successful/unsuccessful use of the "mount" syscall by adding or updating the following rules in the "/etc/audit/rules.d/audit.rules" file:

-a always,exit -F arch=b32 -S mount -F auid>=1000 -F auid!=unset -k privileged-mount
-a always,exit -F arch=b64 -S mount -F auid>=1000 -F auid!=unset -k privileged-mount

The audit daemon must be restarted for the changes to take effect.

Check Contents

Verify that an audit event is generated for any successful/unsuccessful use of the "mount" syscall by performing the following command to check the file system rules in "/etc/audit/audit.rules":

$ sudo grep -w "\-S mount" /etc/audit/audit.rules

-a always,exit -F arch=b32 -S mount -F auid>=1000 -F auid!=unset -k privileged-mount
-a always,exit -F arch=b64 -S mount -F auid>=1000 -F auid!=unset -k privileged-mount

If the command does not return a line, or the line is commented out, this is a finding.
