Title

The DBMS must require users to reauthenticate when organization-defined circumstances or situations require reauthentication. (Cat II impact)

Discussion

The DOD standard for authentication of an interactive user is the presentation of a Common Access Card (CAC) or other physical token bearing a valid, current, DOD-issued Public Key Infrastructure (PKI) certificate, coupled with a Personal Identification Number (PIN) to be entered by the user at the beginning of each session and whenever reauthentication is required. Without reauthentication, users may access resources or perform tasks for which they do not have authorization. When applications provide the capability to change security roles or escalate the functional capability of the application, it is critical the user reauthenticate. In addition to the reauthentication requirements associated with session locks, organizations may require reauthentication 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 reauthentication are privilege escalation and role changes.

Check Content

Review the system documentation and the configuration of the DBMS and related applications and tools. If there are any circumstances under which a user is not required to reauthenticate when changing role or escalating privileges, this is a finding. If the information owner has identified additional cases where reauthentication is needed, but there are circumstances where the system does not ask the user to reauthenticate when those cases occur, this is a finding.

Fix Text

Modify and/or configure the DBMS and related applications and tools so that users are always required to reauthenticate when changing role or escalating privileges. Modify and/or configure the DBMS and related applications and tools so that users are always required to reauthenticate when the specified cases needing reauthorization occur.
