Title
SLEM 5 must generate audit records for a uses of the "chsh" command. (Cat II impact)
Discussion
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.
Check Content
Verify SLEM 5 generates an audit record for all uses of the "chsh" command with the following command: > sudo auditctl -l | grep -w '/usr/bin/chsh' -a always,exit -S all -F path=/usr/bin/chsh -F perm=x -F auid>=1000 -F auid!=-1 -F key=privileged-chsh 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
Configure SLEM 5 to generate an audit record for all uses of the "chsh" command. Add or modify the following line in the "/etc/audit/rules.d/audit.rules" file: -a always,exit -F path=/usr/bin/chsh -F perm=x -F auid>=1000 -F auid!=unset -k privileged-chsh To reload the rules file, restart the audit daemon: > sudo systemctl restart auditd.service or issue the following command: > sudo augenrules --load
