information owner provides authorization for users to gain access
B.
identity management is integrated with human resource processes
C.
information owners periodically review the access controls
D.
An authorization matrix is used to establish validity of access
Explanation:
Personnel and departmental changes can result in authorization creep and can impact the effectiveness of access controls. Many times when personnel leave an organization, or employees are promoted, transferred or demoted, their system access is not fully removed, which increases the risk of unauthorized access. The best practices for ensuring access authorization is still valid is to integrate identity management with human resources processes. When an employee transfers to a different function,access rights are adjusted at the same time.
