Description
Since the accounts in the firewall are privileged or system level accounts, account management is vital to the security of the firewall. Account management by a designated authority ensures access to the firewall is being controlled in a secured manner by granting access to only authorized personnel with the appropriate and necessary privileges. Auditing account modification along with an automatic notification to appropriate individuals will provide the necessary reconciliation that account management procedures are being followed. If modifications to management accounts are not audited, reconciliation of account management procedures cannot be tracked. This requirement is applicable to accounts created or maintained 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.

Check Text ( C-SRG-NET-000007-FW-000007_chk )
Review the firewall configuration to verify the list of configured audit events includes a notice for account modification, such as changes to access or privileges. If there is no viewable, configurable option, request the administrator modify an account and view the logs generated to validate the account modification is logged. If account modification events are not logged, this is a finding.

Fix Text (F-SRG-NET-000007-FW-000007_fix)
Configure the firewall implementation to log all account modifications (e.g., changes to access or privileges).
