Title

CA Common Services installation data sets will be properly protected.

Check text

Refer to the following report produced by the Datadataset Set and Resource Data Collection: - SENSITVE.RPT(CCSRPT). Automated Analysis Refer to the following report produced by the Datadataset Set and Resource Data Collection: - PDI(ZCCS0000). Verify that the accesses to the CA Common Services installation datadatasets sets are properly restricted. If the following guidance is true, this is not a finding. ___ The ACF2 datadataset set rules for the datadatasets setsrestrict restricts READ access to all authorized users. ___ The ACF2 datadataset set rules for the datadatasets setsrestrict restricts WRITE and/or greater access to systems programming personnel. ___ The ACF2 datadataset set rules for the datadatasets sets specify that all (i.e., failures and successes) WRITE and/or greater access is logged.

Fix text

The ISSO will ensure that WRITE and/or greater access to CA Common Services installation datadatasets sets is limited to systems 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 datadatasets, sets and categorize them according to who will have WRITE and/or greater access, and if required, ensure that all WRITE and/or greater access is logged. The installing systems programmer will identify if any additional groups have WRITE and/or greater access for specific data setsdatasets, and once documented will work with the ISSO to seeensure that they are properly restricted to the ACP (Access Control Program) active on the system. DataDatasets sets to be protected may begin with: SYS2.CCS. SYS2A.CCS. SYS3.CCS. The following commands are provided as a sample for implementing datadataset set controls: $KEY(S2C) $PREFIX(SYS2) CCS.- UID(syspaudt) R(A) W(L) A(L) E(A) CCS.- UID(&lttstcaudt>) R(A) W(L) A(L) E(A) CCS.- UID(authorized users/*) R(A) E(A) SET RULE COMPILE 'ACF2.MVA.DSNRULES(S2C)' STORE

Discussion

CA Common Services installation datadatasets sets have the ability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to these datadatasets 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 ACF2 Data Collection: - ACF2CMDS.RPT(ATTSTC). Verify that the logonid(s) for the CA Common Services started task(s) is (are) properly defined. If the following attributes are defined, this is not a finding. STC

Fix text

The IAOISSO working with the systems programmer will ensure the CA Common Services Started Task(s) is properly identified and/or defined to the System ACP. If the product requires a Started Task, verify that it is properly defined to the System ACP with the proper attributes. Most installation manuals will indicate how a Started Task is identified and any additional attributes that must be specified. The following commands are provided as a sample for defining Started Task(s): SET LID insert CAS9 stc name('STC, CAS9')

Discussion

CA Common Services requires a started task that will be restricted to certain resources, datasets, and other system functions. ByDefining defining the started task as a userid to the system ACP, It allows the ACP to control the access and authorized users that require these capabilities. Failure to properly control these capabilities, could compromise of the operating system environment, ACP, and customer data.
