| Upon gaining access to a system, an attacker will often first attempt to create a persistent method of re-establishing 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 security clearance may gain access to critical network nodes.
This requirement is applicable to accounts created using the firewall application itself rather than the underlying OS or an authentication server. Accounts created and maintained on AAA devices (e.g., RADIUS, LDAP, or Active Directory) are secured using the applicable security guide or STIG.
