Description
Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit records can be generated from various components within the information system (e.g., module or policy filter). When a user logs on, the auid is set to the uid of the account that is being authenticated. Daemons are not user sessions and have the loginuid set to -1. The auid representation is an unsigned 32-bit integer, which equals 4294967295. The audit system interprets -1, 4294967295, and "unset" in the same way. Satisfies: SRG-OS-000392-GPOS-00172, SRG-OS-000463-GPOS-00207, SRG-OS-000465-GPOS-00209

Check Text ( C-4660r861012_chk )
Verify the operating system generates audit records when successful/unsuccessful attempts to use the "semanage" command occur. Check the file system rule in "/etc/audit/audit.rules" with the following command: $ sudo grep -w "/usr/sbin/semanage" /etc/audit/audit.rules -a always,exit -F path=/usr/sbin/semanage -F perm=x -F auid>=1000 -F auid!=unset -k privileged-priv_change If the command does not return any output, this is a finding.

Check Text ( C-4660r861012_chk )

Verify the operating system generates audit records when successful/unsuccessful attempts to use the "semanage" command occur.

Check the file system rule in "/etc/audit/audit.rules" with the following command:

$ sudo grep -w "/usr/sbin/semanage" /etc/audit/audit.rules

-a always,exit -F path=/usr/sbin/semanage -F perm=x -F auid>=1000 -F auid!=unset -k privileged-priv_change

If the command does not return any output, this is a finding.

Fix Text (F-4660r861013_fix)
Configure the operating system to generate audit records when successful/unsuccessful attempts to use the "semanage" command occur. Add or update the following rule in "/etc/audit/rules.d/audit.rules": -a always,exit -F path=/usr/sbin/semanage -F perm=x -F auid>=1000 -F auid!=unset -k privileged-priv_change The audit daemon must be restarted for the changes to take effect.
