Overview of intercommunication security

This topic gives an overview of how security works when CICS® systems are interconnected or connected to other compatible systems.

Introduction to intercommunication security
In a single CICS system, you use security to make sure that terminal users can access only those parts of the system they need to work with.
Planning for intercommunication security
Intercommunication security in a CICS system is concerned with incoming requests for access to CICS resources, rather than with requests that are sent to other systems.
Intercommunication bind-time security
Intercommunication link security
Each link between systems is given an authority defined by a userid.
User security for intercommunication
In addition to the security profile that you set up for the link, you can further restrict each remote user's access to the transactions, commands, and resources in your system.
Transaction, resource, command, and surrogate user security for intercommunication
The last step in defining security for your system is to make sure that the access parameters match the profiles you have defined for your transactions, resources, commands, and surrogate users for the link and the individual remote users.
