Details

Upon gaining access to a network device, an attacker will often first attempt to create a persistent method of reestablishing access. One way to accomplish this is to create a new account. Notification of account creation helps to mitigate this risk. Auditing account creation provides the necessary reconciliation that account management procedures are being followed. Without this audit trail, personnel without the proper authorization may gain access to critical network nodes.

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

Solution

Configure the BIG-IP appliance to use an approved remote authentication server that automatically audits the creation of accounts.
