Planning Advanced Program-to-Program Communication security

Use this information to understand how Advanced Program-to-Program Communication (APPC) works and how you can set up the appropriate security for APPC on your system.

APPC allows programs on IBM i to communicate with programs on other systems having compatible communications support. Display station pass-through, distributed data management, and personal computers can use APPC.

When your system participates in a network with other systems, a new set of doors and windows to your system becomes available. As security administrator, you should be aware of the options that you can use to control the entrances to your system in an APPC environment.

Tip: Many methods for connecting PCs to your system servers depend on communications, such as APPC or TCP/IP. Be sure to consider the security issues for connecting to both other systems and to PCs. When you plan your network protection, make sure that you do not adversely affect the PCs that are attached to your system.
