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.

Fix:Configure the SUSE operating system to generate an audit record for all uses of the "umount" and "umount2" system calls. Add or update the following rules to "/etc/audit/rules.d/audit.rules": -a always,exit -F arch=b32 -S umount -F auid>=1000 -F auid!=4294967295 -k privileged-umount -a always,exit -F arch=b32 -S umount2 -F auid>=1000 -F auid!=4294967295 -k privileged-umount -a always,exit -F arch=b64 -S umount2 -F auid>=1000 -F auid!=4294967295 -k privileged-umount To reload the rules file, restart the audit daemon > sudo systemctl restart auditd.service or issue the following command: > sudo augenrules --load
