At a minimum, the audit system should collect media exportation events for all users and root. Add the following to "/etc/audit/audit.rules:
-a always,exit -F arch=b32 -S mount -F auid>=500 -F auid!=4294967295 -k export
-a always,exit -F arch=b32 -S mount -F auid=0 -k export
If the system is 64-bit, then also add the following:
-a always,exit -F arch=b64 -S mount -F auid>=500 -F auid!=4294967295 -k export
-a always,exit -F arch=b64 -S mount -F auid=0 -k export
To verify that auditing is configured for all media exportation events, run the following command:
$ sudo grep -w "mount" /etc/audit/audit.rules
-a always,exit -F arch=b32 -S mount -F auid>=500 -F auid!=4294967295 -k export
-a always,exit -F arch=b32 -S mount -F auid=0 -k export
-a always,exit -F arch=b64 -S mount -F auid>=500 -F auid!=4294967295 -k export
-a always,exit -F arch=b64 -S mount -F auid=0 -k export
If the system is 64-bit and does not return rules for both "b32" and "b64" architectures, this is a finding.
If no line is returned, this is a finding.
