Why Security for APPC? z/OS MVS Planning: APPC/MVS Management SA23-1388-00 |
|
Cooperative processing allows application programs to establish communications with partner programs on other systems, and to share work, data, and services between systems and across networks. This ability to access other programs and all the resources at their disposal poses special security considerations for installations that use cooperative processing. APPC/MVS is a cooperative processing interface on MVS/ESA. With
APPC/MVS, transaction programs (TPs) on MVS can initiate (allocate)
conversations with partner programs on systems throughout an SNA network.
The partner programs can likewise allocate conversations with TPs
on MVS. In an unprotected network, all a TP has to know to start
a conversation is the name of an inbound TP and the logical unit (LU)
on which the inbound TP is located. Unless certain precautions are
taken, it is possible for unauthorized conversations to take place.
To protect your z/OS system
from unauthorized conversation requests, you might want to take some
of the following steps:
This chapter discusses these and other security mechanisms for cooperative processing and describes how you can implement them using APPC/MVS and RACF®. |
