Description
Separation of duties is a prevalent Information Technology control implemented at different layers of the information system including the operating system and in applications. It serves to eliminate or reduce the possibility that a single user may carry out a prohibited action. Separation of duties requires the person accountable for approving an action not be the same person tasked with implementing the action. This requirement is intended to limit exposure due to users (or entities acting on behalf of users) being used to operate from within a privileged account or role. Limiting the access and permissions of privileged accounts to the minimum required, reduces exposure if the account is compromised and provides forensic history of activity when operating from these accounts. See TechNet Article cc678863 for information regarding required permission. The setup user administrator account is used during initial creation of the farm, to update the farm servers, and to configure certain farm configuration option. The setup user administrator account should be limited to membership in the Domain Users group in Active Directory.
