(RACF0290: CAT II) EGN changes the meaning of the signle generic character *. 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 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 migration process or contingency plan activation.
a) Refer to the following report produced by the RACF Data Collection: - RACFCMDS.RPT(SETROPTS) Automated Analysis Refer to the following report produced by the RACF Data Collection: - PDI(RACF0290) b) If the EGN (ENHANCED GENERIC NAMING) IS IN EFFECT, there is NO FINDING. c) If the EGN (ENHANCED GENERIC NAMING) IS NOT IN EFFECT, this is a FINDING.
The IAO will ensure that EGN SETROPTS value is set to EGN. This allows the generic character ** when you define dataset profiles.. Evaluate the impact associated with implementation of the control option. Develop a plan of action to implement the control option as specified in the example below: The RACF Command SETR LIST will show the status of RACF Controls including a status of Enhanced Generic Naming. (1) Enhanced Generic Naming is activated with the command SETR EGN.
