IMS Security Features

CA Top Secret provides extensive and flexible security protection for IMS transactions, applications, resources, and regions in the following IMS/DC environments:

• Message Processing Regions (MPP)
• Batch Message Regions (BMP)
• Fast Path Regions (FP)

Because IMS utilizes MVS's Standard Security Interface to drive CA Top Secret, CA Top Secret is completely compatible with IMS. No modifications to IMS or IMS installation exits are required. Some parameter changes to the plain vanilla IMS security macro, however, are required to establish what is to be protected by CA Top Secret security and what is to be protected by IMS default security (SMU). For example, CA Top Secret only protects IMS commands for IMS release 4.1 and above. Therefore, for prior releases of IMS, SMU security must continue to be used for command security.

In addition to special IMS security features, many of the standard CA Top Secret security mechanisms apply. Among the most useful are:

• Signon Security
• Password Validation
• Terminal Security
• Authorization Restrictions
• Job Submission Validation
• Security Administration
• Multiple Signons
