Check: PHTN-67-000001
VMware vSphere 6.7 Photon OS STIG:
PHTN-67-000001
(in versions v1 r6 through v1 r2)
Title
The Photon operating system must audit all account creations. (Cat II impact)
Discussion
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 Content
At the command line, execute the following command: # auditctl -l | grep -E "(useradd|groupadd)" Expected 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. Enabling the auditd service is done as part of a separate control.
Fix Text
Open /etc/audit/rules.d/audit.STIG.rules with a text editor and add the following lines: -w /usr/sbin/useradd -p x -k useradd -w /usr/sbin/groupadd -p x -k groupadd At the command line, execute the following command: # /sbin/augenrules --load
