| Description |

| ROSCOE Install data sets provide the capability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to their data sets could result in violating the integrity of the base product which could result in compromising the operating system or sensitive data. |

| a) Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(ROSRPT) Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZROS0000) b) Verify that access to the ROSCOE Install data sets are properly restricted. ___ The TSS data set rules for the data sets does not restrict UPDATE and/or ALTER access to systems programming personnel. ___ The TSS data set rules for the data sets does not specify that all (i.e., failures and successes) UPDATE and/or ALTER access will be logged. c) If all of the above are untrue, there is NO FINDING. d) If any of the above is true, this is a FINDING. |

| The IAO will ensure that update and allocate/create access to program product data sets is limited to System Programmers only, and all update and allocate/create access is logged. Security Personnel and Auditors should have read access. The installing Systems Programmer will identify and document the product data sets and categorize them according to who will have update and allocate/create access and if required that all update and allocate/create access is logged. He will identify if any additional groups have update access for specific data sets, and once documented he will work with the IAO to see that they are properly restricted to the ACP (Access Control Program ) active on the system. Data sets to be protected will be: SYS2.ROSCOE SYS2A.ROSCOE SYS3.ROSCOE SYS3A.ROSCOE The following commands are provided as a sample for implementing dataset controls: TSS PERMIT(syspaudt) DSN(SYS2.ROSCOE.)
