| Description |
|---|
| Reconstruction of harmful events or forensic analysis is not possible if audit records do not contain enough information. At a minimum, the organization must audit the full-text recording of privileged commands. The organization must maintain audit trails in sufficient detail to reconstruct events to determine the cause and impact of compromise.

| Verify the SUSE operating system generates an audit record for all uses of the "umount" command. Check that the following command call is being audited by performing the following command on the system rules in "/etc/audit/audit.rules": # sudo grep -i umount /etc/audit/audit.rules -a always,exit -F arch=32 -S umount -F auid>=1000 -F auid!=4294967295 -k privileged-umount -a always,exit -F arch=64 -S umount -F auid>=1000 -F auid!=4294967295 -k privileged-umount If the command does not return any output, this is a finding. |
