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 that an audit event is generated for any successful/unsuccessful use of the "sudo" command by performing the following command to check the file system rules in "/etc/audit/audit.rules": $ sudo grep -w sudo /etc/audit/audit.rules -a always,exit -F path=/usr/bin/sudo -F perm=x -F auid>=1000 -F auid!=unset -k priv_cmd If the command does not return a line, or the line is commented out, this is a finding.
Configure the audit system to generate an audit event for any successful/unsuccessful use of the "sudo" command by adding or updating the following rule in the "/etc/audit/rules.d/audit.rules" file: -a always,exit -F path=/usr/bin/sudo -F perm=x -F auid>=1000 -F auid!=unset -k priv_cmd The audit daemon must be restarted for the changes to take effect.
