MPE/iX provides two methods of establishing and maintaining file security.

access control definitions (ACD) for file and devices
traditional file security For disk files only

ACDs are implemented to provide a security mechanism that meets standards set forth by the National Computer Security Center. Traditional file security works through the mechanism long available on MPE systems. ACDs override any security measures implemented by traditional means. In addition, MPE/iX now provides logging facilities to track ACD security-related transactions.

ACDs are discussed first in this chapter, followed by topics relating to the traditional mechanisms of file security.
