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 SLEM 5 generates an audit record for all uses of the "passwd" command with the following command: > sudo auditctl -l \| grep -w '/usr/bin/passwd' -a always,exit -S all -F path=/usr/bin/passwd -F perm=x -F auid>=1000 -F auid!=-1 -F key=privileged-passwd If the command does not return any output, this is a finding. Note: The "key=" value is arbitrary and can be different from the example output above.

Fix Text (F-65075r996720_fix)
Configure SLEM 5 to generate an audit record for all uses of the "passwd" command. Add or modify the following line in the "/etc/audit/rules.d/audit.rules" file: -a always,exit -F path=/usr/bin/passwd -F perm=x -F auid>=1000 -F auid!=unset -k privileged-passwd To reload the rules file, restart the audit daemon: > sudo systemctl restart auditd.service or issue the following command: > sudo augenrules --load
