|
||
The base DBMS PP Security Problem Definition does not include a security objective relating to access history.
|
||
While many organizations do not specify this objective as part of their security problem definition, this additional security objective may need to be included in the security problem definition by some organizations in order to support further mitigation of the threats of T.ACCESS_TSFDATA, T.IA_MASQUERADE and T.TSF_COMPROMISE. This is achieved by allowing trained users to review their access history in order to help identify unauthorized access attempts.
|
||
This extended package supplements the DBMS PP by adding the TOE Security Objective O.ACCESS-HISTORY and the security functional requirement supporting that objective.
