The DataPower Gateway must require users to re-authenticate when privilege escalation or role changes occur.

Without re-authentication, users may access resources or perform tasks for which they do not have authorization. When devices provide the capability to change security roles, it is critical the user re-authenticate. In addition to the re-authentication requirements associated with session locks, organizations may require re-authentication of individuals and/or devices in other situations, including (but not limited to) the following circumstances. (i) When authenticators change; (ii) When roles change; (iii) When security categories of information systems change; (iv) When the execution of privileged functions occurs; (v) After a fixed period of time; or (vi) Periodically. Within the DoD, the minimum circumstances requiring re-authentication are privilege escalation and role changes.
