Description
To ensure accountability and prevent unauthenticated access, organizational users must be uniquely identified and authenticated to prevent potential misuse and compromise of the system. Sharing of accounts prevents accountability and non-repudiation. Organizational users must be uniquely identified and authenticated for all accesses. The use of an organizational level authentication mechanism provides centralized management of accounts, and provides many benefits not normally leveraged by local account mechanisms.
