PHTN-67-000001 - The Photon operating system must audit all account creations - useradd

Details

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.


Solution

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
# /sbin/augenrules --load
