Establishing IMSplex security

The way you protect the IMS online system does not change for an IMS system in an IMSplex. The resources that can be protected and the facilities available to protect them are similar. The types of security issues that exist for a standalone IMS system also exist for an IMS system within an IMSplex.

The basic decisions you must make when implementing security for IMS include:

Determine what resources need to be protected.
Determine which users need access to the resources.
Determine the level of access to a resource that the users need.

In addition to the security checks made for standalone IMS systems, an IMSplex with a CSL performs additional security checks.
