Description
This requirement is intended to limit exposure due to operating from within a privileged account or role. The inclusion of role is intended to address those situations where an access control policy, such as Role Based Access Control (RBAC), is being implemented and where a change of role provides the same degree of assurance in the change of access authorizations for both the user and all processes acting on behalf of the user as would be provided by a change between a privileged and non-privileged account. DBAs, if assigned excessive OS privileges, could perform actions that could endanger the information system or hide evidence of malicious activity.
