Access security is the part of a security plan that controls access to data and functions. Without access security, individual user authorizations are not validated. Therefore, any user who can communicate with the Multi-User Facility (MUF) can obtain and modify data. CA Datacom security allows you to control access by providing security models.
With CA Datacom Datadictionary internal security and CA Dataquery internal security, each product is protected by access rules defined and maintained within that product. To protect CA Datacom Datadictionary and CA Dataquery with internal security, learn the security systems associated with each product.
External security provides the ability to control and administer user access to CA Datacom products and data based on the security profiles that exist in the external security product, such as CA ACF2, CA Top Secret, or RACF (z/OS).
The difference between external and internal security is where the user access authorizations are maintained.
