The NJE GSO record value must indicate validation options that apply to jobs submitted through a network job entry subsystem (JES2, JES3, RSCS).

Description
The system-wide options control the default settings for determining how the ACP will function when handling requests for access to the operating system environment, ACP, and customer data. The ACP provides the ability to set a number of these fields at the subsystem level. If no setting is found, the system-wide defaults will be used. The improper setting of any one of these fields, individually or in combination with another, can compromise the security of the processing environment. In addition, failure to establish standardized settings for the ACP control options introduces the possibility of exposure during a migration process or contingency plan activation.

Specifies ACF2 validation options that apply to jobs submitted through a network job entry subsystem (JES2, JES3, RSCS). Example: DFTLID() INHERIT NODEMASK(-) ENCRYPT VALIN(YES) NOVALOUT NOTE: For NJE nodes that are incompatible with the XDES algorithm, discrete NJE records will be created with NOENCRYPT. NOTE: Local changes will be documented in writing with supporting documentation. c) If there is any deviation from the above requirements in the GSO NJE record values, this is a FINDING.
