The Photon operating system must audit all account creations.


Overview

Finding ID Version Rule ID IA Controls Severity
V-239073 PHTN-67-000001 SV-239073r675027_rule Medium
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-42284r675025_chk )
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.
Fix Text (F-42243r675026_fix)
At the command line, execute the following commands:

# echo '-w /usr/sbin/useradd -p x -k useradd' >> /etc/audit/rules.d/audit.STIG.rules
# echo '-w /usr/sbin/groupadd -p x -k groupadd' >> /etc/audit/rules.d/audit.STIG.rules
