Fix Recommendation

The ISSO will ensure that READ, UPDATE, and ALL access to program product user data sets is limited to systems programmers, security personnel, and auditors and all WRITE and/or greater access is logged.

The installing systems programmer will identify and document the product user 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. The installing systems programmer will identify if any additional groups have UPDATE access for specific data sets, and once documented will work with the ISSO to ensure 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 data set 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)
TSS PER(audtaudt) DSN(SYS3.FSO.) ACC(A) ACTION(AUDIT)

Refer to the following report produced by the Data Set and Resource Data Collection:

- SENSITVE.RPT(SRRUSER).

Automated Analysis
Refer to the following report produced by the Data Set and Resource Data Collection:

- PDI(ZSRR0002).

Verify that access to the SRRAUDIT User data sets are properly restricted. If the following guidance is true, this is not a finding.

The TSS data set rules for the data sets restrict READ and/or greater access to systems programming personnel, security personnel, and auditors.

The TSS data set rules for the data sets specify that all (i.e., failures and successes) WRITE and/or greater access will be logged.
