F5BI-DM-000171 - The BIG-IP appliance must be configured to automatically audit account-enabling actions.

Information

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 enable a new or disabled account. Notification of account enabling is one method for mitigating this risk. A comprehensive account management process will ensure an audit trail that documents the creation of application user accounts and notifies administrators and Information System Security Officers (ISSO). Such a process greatly reduces the risk that accounts will be surreptitiously created and provides logging that can be used for forensic purposes.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Configure the BIG-IP appliance to use a properly configured remote authentication server to automatically audit account-enabling actions.
