Security for Other Cross-system Operations

There are two categories of cross-system operations:

• Display- or query-type operations that do not affect the state of the system or CA OPS/MVS. An example of this type of operation is the use of the cross-system OPSLOG Browse facility.
• Update-type operations that alter the state of the system or CA OPS/MVS. An example of this type of operation is a cross-system ADDRESS SQL UPDATE.

When you define the remote systems on each system, you specify whether each remote system is considered to be a SECURE system. SECURE remote systems can send both query- and update-type operations to this system. Systems that are defined as NOSECURE systems can only send display- or query-type operations to this system. For example, if you connect a non-secure test system to your production systems through the MSF, you should specify the NOSECURE keyword on the ADDRESS OPSCTL MSF DEFINE statement when defining the test system as a remote MSF system to each of the production systems.
