The Photon operating system must generate audit records when the sudo command is used.

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).

Satisfies: SRG-OS-000458-GPOS-00203, SRG-OS-000463-GPOS-00207

At the command line, run the following command:

# auditctl -l | grep sudo

Expected result:

-a always,exit -S all -F path=/usr/bin/sudo -F perm=x -F auid>=1000 -F auid!=-1 -F key=privileged

If the output does not match the expected result, this is a finding.

Note: The auid!= parameter may display as 4294967295 or -1, which are equivalent.

Note: This check depends on the auditd service to be in a running state for accurate results. The auditd service is enabled in control PHTN-30-000013.

Navigate to and open:

/etc/audit/rules.d/audit.STIG.rules

Add the following line:

-a always,exit -F path=/usr/bin/sudo -F perm=x -F auid>=1000 -F auid!=4294967295 -F key=privileged

Execute the following command to load the new audit rules:

# /sbin/augenrules --load

Note: A new "audit.STIG.rules" file is provided for placement in "/etc/audit/rules.d" that contains all rules needed for auditd.

Note: An older "audit.STIG.rules" may exist if the file exists and references older "GEN" SRG IDs. This file can be removed and replaced as necessary with an updated one.
