RACF/DB2 External Security Module
The Security Server for OS/390 Release 4 is providing a new function that gives
you the ability to control access to DB2 objects using RACF profiles. This function
is provided as a fully supported exit module called the RACF/DB2 external security
module. If you choose to use this new support, the module is designed to receive
control from the DB2 access control authorization exit point. The highlights of the
support include:
Single point of control for administering and auditing DB2 access
Ability to define security rules before a DB2 object is created
Ability to have security rules persist when a DB2 object is dropped
Ability to control access to DB2 objects with generic profiles
Flexibility to control access to DB2 objects for single or multiple subsystems
with a single set of RACF profiles
Ability to validate a user ID before permitting it access to a DB2 object
Elimination of DB2 cascading revoke
Use of this function requires the DB2 access control authorization exit point function
provided in DB2 Version 5.
