CA 1 Tape Management installation data sets have the ability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to these data sets could result in violating the integrity of the base product which could result in compromising the operating system or sensitive data.
Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(CA1PROD) Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZCA10000) Verify that the accesses to the CA 1 Tape Management installation data sets are properly restricted. If the following guidance is true, this is not a finding. ___ The RACF data set rules for the data sets restricts READ access to all authorized users. ___ The RACF data set rules for the data sets restricts WRITE and/or greater access to systems programming personnel. ___ The RACF data set rules for the data sets specify that all (i.e., failures and successes) WRITE and/or greater access is logged. ___ The RACF data set rules for the data sets specify UACC(NONE) and NOWARNING.
Ensure that WRITE and/or greater access to CA 1 Tape Management installation data sets is limited to System Programmers only, and all WRITE and/or greater access is logged. READ access can be given to all authorized users. The installing Systems Programmer will identify and document the product data sets and categorize them according to who will have WRITE and/or greater access and if required that all WRITE and/or greater access is logged. He will identify if any additional groups have WRITE and/or greater 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. The following is an example of the type of data sets to be protected: SYS2.CA1. SYS2A.CA1.*.CAILIB SYS2A.CA1.*.CAILPA Or SYS2A.CA1.*.CTAPLINK SYS3.CA1. SYS3A.CA1.*.CAILIB Or SYS3A.CA1.*.CTAPLINK SYS3A.CA1.*.CTAPLPA The following commands are provided as a sample for implementing data set controls: AD 'sys2.ca1.v**' UACC(NONE) OWNER(SYS2) AUDIT(SUCCESS(UPDATE) FAILURES(READ)) AD 'sys2a.ca1.v*.cailib.**' UACC(NONE) OWNER(SYS2A) AUDIT(SUCCESS(UPDATE) FAILURES(READ)) AD 'sys2a.ca1.v*.cailpa.**' UACC(NONE) OWNER(SYS2A) AUDIT(SUCCESS(UPDATE) FAILURES(READ)) Or AD 'sys2a.ca1.v*.ctaplink.**' UACC(NONE) OWNER(SYS2A) AUDIT(SUCCESS(UPDATE) FAILURES(READ)) AD 'sys3.ca1.**' UACC(NONE) OWNER(SYS3) AUDIT(SUCCESS(UPDATE) FAILURES(READ)) AD 'sys3a.ca1.v*.cailib.**' UACC(NONE) OWNER(SYS3A) AUDIT(SUCCESS(UPDATE) FAILURES(READ)) Or AD 'sys3a.ca1.v*.ctaplink.**' UACC(NONE) OWNER(SYS3A) AUDIT(SUCCESS(UPDATE) FAILURES(READ)) AD 'sys3a.ca1.v*.ctaplpa.**' UACC(NONE) OWNER(SYS3A) AUDIT(SUCCESS(UPDATE) FAILURES(READ)) PE 'sys2.ca1.v**' ID(syspaudt) ACC(A) PE 'sys2.ca1.v**' ID(authorized users/*) ACC(R) PE 'sys2a.ca1.v*.cailib.**' ID(syspaudt) ACC(A) PE 'sys2a.ca1.v*.cailib.**' ID(authorized users/*) ACC(R) PE 'sys2a.ca1.v*.cailpa.**' ID(syspaudt) ACC(A) PE 'sys2a.ca1.v*.cailpa.**' ID(authorized users/*) ACC(R) Or PE 'sys2a.ca1.v*.ctaplink.**' ID(syspaudt) ACC(A) PE 'sys2a.ca1.v*.ctaplink.**' ID(authorized users/*) ACC(R) PE 'sys3.ca1.v**' ID(syspaudt) ACC(A) PE 'sys3.ca1.v**' ID(authorized users/*) ACC(R) PE 'sys3a.ca1.v*.cailib.**' ID(syspaudt) ACC(A) PE 'sys3a.ca1.v*.cailib.**' ID(authorized users/*) ACC(R) Or PE 'sys3a.ca1.v*.ctaplink.**' ID(syspaudt) ACC(A) PE 'sys3a.ca1.v*.ctaplink.**' ID(authorized users/*) ACC(R) PE 'sys3a.ca1.v*.ctaplpa.**' ID(syspaudt) ACC(A) PE 'sys3a.ca1.v*.ctaplpa.**' ID(authorized users/*) ACC(R)
