Title
The TAPEDSN SETROPTS value specified is improperly set. (Cat II impact)
Discussion
TAPEDSN activates tape data set protection. When tape data set protection is in effect, RACF can protect individual tape data sets as well as tape volumes. 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.
Check Content
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(RACF0550) b) If the TAPEDSN is enabled then the message "TAPE DATA SET PROTECTION IS ACTIVE" will be displayed, there is NO FINDING. NOTE 1: TAPEDSN should be active for domains without a tape management product. NOTE 2: For domains running CA 1, Computer Associates recommends that TAPEDSN be active and CA 1 parameter OCEOV be set to OFF. c) If the TAPEDSN value is set to INACTIVE, this is a FINDING.
Fix Text
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 the value for the TAPEDSN Option. (1) TAPEDSN is ACTIVATED by issuing the command SETR TAPEDSN.
