Fix Recommendation

The IAO will ensure that read, update, and allocate access to program product user data sets is limited to System Programmers, Security Personnel, and Auditors and all update and allocate access is logged.

The installing System Programmer will identify and document the product user data sets and categorize them according to who will have update and allocate access and if required that all update and allocate 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 set prefix to be protected will be:

SYS3.SRRAUDIT.

If doing a full SRR review using the z/OS STIG Instruction, the following data set prefix to be protected will be:

SYS3.FSO.

The following commands are provided as a sample for implementing dataset controls:

TSS ADD(SYS3) DSN(SYS3)
TSS PER(syspaudt) DSN(SYS3.SRRAUDIT.) ACC(R)
TSS PER(secaaudt) DSN(SYS3.SRRAUDIT.) ACC(R)
TSS PER(audtaudt) DSN(SYS3.SRRAUDIT.) ACC(R)
TSS PER(syspaudt) DSN(SYS3.SRRAUDIT.) ACC(A) ACTION(AUDIT)
TSS PER(secaaudt) DSN(SYS3.SRRAUDIT.) ACC(A) ACTION(AUDIT)
TSS PER(audtaudt) DSN(SYS3.SRRAUDIT.) ACC(A) ACTION(AUDIT)

TSS PER(syspaudt) DSN(SYS3.FSO.) ACC(R)
TSS PER(secaaudt) DSN(SYS3.FSO.) ACC(R)
TSS PER(audtaudt) DSN(SYS3.FSO.) ACC(R)
TSS PER(syspaudt) DSN(SYS3.FSO.) ACC(A) ACTION(AUDIT)
TSS PER(secaaudt) DSN(SYS3.FSO.) ACC(A) ACTION(AUDIT)

b) Verify that access to the SRRAUDIT User data sets are properly restricted.

___ The TSS data set rules for the data sets does not restrict READ, UPDATE, and/or ALTER access to systems programming personnel, security personnel, and auditors.

___ The TSS data set rules for the data sets do not specify that all (i.e., failures and successes) UPDATE and/or ALTER access will be logged.

b) If all of the above are untrue, there is NO FINDING.
