The Photon operating system must audit all account creations.

| Description | ||||
| Once an attacker establishes access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to create an account. Auditing account creation actions provides logging that can be used for forensic purposes.

Check Text (C-258801r933464_chk)
At the command line, run the following command to verify an audit rule exists to audit account creations:
# auditctl -l | grep -E "(useradd|groupadd)"
Example result:
-w /usr/sbin/useradd -p x -k useradd
-w /usr/sbin/groupadd -p x -k groupadd
If either "useradd" or "groupadd" are not listed with a permissions filter of at least "x", this is a finding.
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-40-000016.
Fix Text (F-62450r933463_fix)
Navigate to and open:
/etc/audit/rules.d/audit.STIG.rules
Add or update the following lines:
-w /usr/sbin/useradd -p x -k useradd
-w /usr/sbin/groupadd -p x -k groupadd
At the command line, run the following command to load the new audit rules:
# /sbin/augenrules --load
Note: An "audit.STIG.rules" file is provided with this guidance for placement in "/etc/audit/rules.d" that contains all rules needed for auditd.
Note: An older "audit.STIG.rules" may exist and may reference older "GEN" SRG IDs. This file can be removed and replaced as necessary with an updated one.
