Vulnerability discussion

If components of the FEPs are not properly protected they can be stolen, damaged, or disturbed. Without adequate physical security, unauthorized users can access the control panel, the operator console, and the diskette drive of the service subsystem. Therefore, they can interfere with the normal operations of the FEPs. Improper control of FEP components could compromise network operations.

Fix text

Identify Names of the following data sets used for installation and in development/production environments: - NCP system data sets - NCP source definition data sets - NCP load modules - NCP host dump data sets - NCP utility programs Have the IAO validate that they are properly protected by the ACP. And that only authorized personnel are permitted UPDATE and/or ALLOCATE access (e.g., z/OS systems programming personnel).
