Discussion

A comprehensive account management process such as provided by External Security Managers (ESM) which includes automation helps to ensure accounts designated as requiring attention are consistently and promptly addressed. Examples include, but are not limited to, using automation to take action on multiple accounts designated as inactive, suspended, or terminated, or by disabling accounts located in non-centralized account stores such as multiple servers. This requirement applies to all account types, including individual/user, shared, group, system, guest/anonymous, emergency, developer/manufacturer/vendor, temporary, and service. DTCPARMS setting assures that an ESM is enabled. Account management functions include: assigning group or role membership; identifying account type; specifying user access authorizations (i.e., privileges); account removal, update, or termination; and administrative alerts.

:ESM_Enable.YES
:ESM_Racroute.YES (or a valid exit name)
:ESM_Validate.YES (or a valid exit name)
