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.

ℹ️ Check
Verify the audit daemon is configured for full-text recording of privileged commands: The log file can be set by the "trail" variable in /etc/security/audit/config. # grep trail /etc/security/audit/config trail = /audit/trail Note: The default log file is /audit/trail. Use the following command to display the audit events: # /usr/sbin/auditpr -i <audit log file> -v event login status time command wpar name --------------- -------- ----------- ------------------------ ------------------ ------------- ------------------------- S_PASSWD_READ root OK Sat Aug 26 19:35:00 2017 cron Global audit object read event detected /etc/security/passwd S_PASSWD_READ root OK Sat Aug 26 19:35:00 2017 cron Global audit object read event detected /etc/security/passwd CRON_Start root OK Sat Aug 26 19:35:00 2017 cron Global event = start cron job cmd = /usr/sbin/dumpctrl -k >/dev/null 2>/dev/nul l time = Sat Aug 26 19:35:00 2017 FS_Chdir root OK Sat Aug 26 19:35:00 2017 cron Global change current directory to: / If the full-text recording of privileged command is not displayed, this is a finding.

✔️ Fix
Reset the audit system with the following command: # /usr/sbin/audit shutdown Start the audit system with the following command: # /usr/sbin/audit start
