The CLASMAP GSO record value translates an eight-character SAF resource class into a three character ACF2 resource type code.

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.

Translates an eight-character SAF resource class into a three character ACF2 resource type code to enable resource rules to be written to perform validation. Also it translates the resource type codes for ACF2 calls or calls made to ACF2 from CA's International Standard Security Facility (CAISSF). Vendor defaults as specified in the internal CLASMAP records unless as indicated otherwise below. The following resource class to resource type translations are the recommended standard: APPL maps to APL, CONSOLE maps to CON, FACILITY maps to FAC, OPERCMDS maps to OPR, and TSOAUTH maps to TSO c) If there is any deviation from the above requirements in the GSO CLASMAP record values, this is a FINDING.
