Implementing APPC Security

To secure APPC conversations:

Review your resources and determine what degree of security you need
Secure the ASCH, ASCHINT, and APPC started tasks and permit them to the APPC facility for minimal security
Specify which LUs can establish sessions by:
- Adding the appropriate parameters to the VTAM APPL statement
- Defining remote and partner LUs to the CA Top Secret APPCLU record
- Identifying which sessions are reserved for APPC use
Determine how TP profile and side‑information data sets are maintained (with or without database tokens)
Secure individual user access to APPC resources by adding new authorization restrictions to the profile records
