Check: PHTN-30-000001
VMware vSphere 7.0 vCenter Appliance Photon OS STIG:
PHTN-30-000001
(in versions v1 r3 through v1 r1)
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, run 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. The "auditd" service is enabled in control PHTN-30-000013.
Fix Text
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: 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 and may reference older "GEN" SRG IDs. This file can be removed and replaced as necessary with an updated one.
