Description

Once an attacker establishes initial 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 simply create a new account. Auditing of account creation mitigates this risk. To address access requirements, many operating systems may be integrated with enterprise-level authentication/access/auditing mechanisms that meet or exceed access control policy requirements.

Check Text ( C-43578r670774_chk )
Determine if execution of the useradd and groupadd executable are audited. # auditctl -l | egrep '(useradd|groupadd)' If either useradd or groupadd are not listed with a permissions filter of at least "x", this is a finding. Expected result: LIST_RULES: exit,always watch=/usr/sbin/useradd perm=x key=useradd LIST_RULES: exit,always watch=/usr/sbin/groupadd perm=x key=groupadd

Fix Text (F-43537r670775_fix)
Configure execute auditing of the useradd and groupadd executables. Run the dodscript with the following command as root: # /etc/dodscript.sh OR Configure execute auditing of the useradd and groupadd executables. Add the following to /etc/audit/audit.rules: -w /usr/sbin/useradd -p x -k useradd -w /usr/sbin/groupadd -p x -k groupadd Restart the auditd service: # service auditd restart
