SLEM 5 must generate audit records for all account creations, modifications, disabling, and termination events that affect /etc/shadow.

| Finding ID | Version | Rule ID | IA Controls | Severity |

| 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 account creation mitigates this risk. To address access requirements, SLEM 5 may be integrated with enterprise-level authentication/access/auditing mechanisms that meet or exceed access control policy requirements. | ||||

Check Text (C-261452r996763_chk)
Verify SLEM 5 generates an audit record when modifications occur to the "/etc/shadow" file with the following command:
> sudo auditctl -l | grep -w '/etc/shadow'
-w /etc/shadow -p wa -k account_mod
If the command does not return a line that matches the example or the line is commented out, this is a finding.
Notes: The "-k" allows for specifying an arbitrary identifier. The string following "-k" does not need to match the example output above.
Fix Text (F-65089r996762_fix)
Configure SLEM 5 to generate an audit record when all modifications to the "/etc/shadow" file occur.
Add or modify the following line in the "/etc/audit/rules.d/audit.rules" file:
-w /etc/shadow -p wa -k account_mod
To reload the rules file, restart the audit daemon:
> sudo systemctl restart auditd.service
or issue the following command:
> sudo augenrules --load
