Fix Recommendation

The ISSO will ensure that WRITE and/or greater access to program product data sets is limited to system programmers, security personnel and auditors only, and all WRITE and/or greater access is logged.

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. 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 Access Control Program (ACP) active on the system.

Data set prefix to be protected will be:

SYS2.ROSCOE.
SYS2A.ROSCOE.
SYS3.ROSCOE.
SYS3A.ROSCOE.

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

ad 'sys2.roscoe.**' uacc(none) owner(sys2) -
audit(success(update) failures(read)) -
data('Vendor DS Profile: ROSCOE')
pe 'sys2.roscoe.**' id(syspaudt) acc(a)
pe 'sys2.roscoe.**' id(*) acc(r)
ad 'sys2a.roscoe.**' uacc(none) owner(sys2a) -
audit(success(update) failures(read)) -
data('Roscoe Vendor Datasets')
pe 'sys2a.roscoe.**' id(<syspaudt>) acc(a)
pe 'sys2a.roscoe.**' id(*) acc(r)
ad 'sys3.roscoe.**' uacc(none) owner(sys3) -
audit(success(update) failures(read)) -
data('Roscoe Vendor Datasets')
pe 'sys3.roscoe.**' id(<syspaudt>) acc(a)
pe 'sys3.roscoe.**' id(*) acc(r)
ad 'sys3a.roscoe.**' uacc(none) owner(sys3a) -
audit(success(update) failures(read)) -
data('Roscoe Vendor Datasets')

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

- PDI(ZROS0000).

Verify that access to the ROSCOE Install data set are properly restricted. If the following guidance is true, this is not a finding.

The RACF data set rules for the data sets restrict 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 will be logged.
