The Photon operating system must audit all account modifications.

An XCCDF Rule

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 modify an existing account. Auditing account modification actions provides logging that can be used for forensic purposes. To address access requirements, many operating systems can be integrated with enterprise-level authentication/access/auditing mechanisms that meet or exceed access control policy requirements.

Remediation Templates

Navigate to and open:

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

Add or update the following lines:
-w /etc/passwd -p wa -k passwd
-w /etc/shadow -p wa -k shadow
-w /etc/group -p wa -k group
-w /etc/gshadow -p wa -k gshadow

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.
