Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZMVZ0000). Verify that the accesses to the BMC MAINVIEW for z/OS installation 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 restrictsrestrict READ access to all authorized users. The TSS data set rules for the data sets restrictsrestrict UPDATEWRITE and/or ALLgreater access to systems programming personnel. The TSS data set rules for the data sets specify that all (i.e., failures and successes) UPDATEWRITE and/or ALLgreater access are logged.

The ISSO will ensure that updateWRITE and/or allocategreater access to BMC MAINVIEW for z/OS installation data sets is limited to systemsystems programmers only, and all updateWRITE and/or allocategreater access is logged. Read 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 updateWRITE and/or altergreater access and if required that all updateWRITE and/or allocategreater access is logged. The installing systems programmer will identify if any additional groups have updateWRITE and/or altergreater 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 sets to be protected will be: SYS2.BMCVIEW. SYS3.BMCVIEW.

If the following guidance is true, this is not a finding. The TSS resources are owned or DEFPROT is specified for the resource class. The TSS resource access authorizations restrict access to the appropriate personnel.

The BMC Mainview for z/OS systemsystems programmer and the IAOISSO will ensure that a product's Started Task(s) is properly identified and/or defined to the Systemsystem ACP. If the product requires a Started Task, verify that it is properly defined to the Systemsystem ACP with the proper attributes. Most installation manuals will indicate how the Started Task is identified and any additional attributes that must be specified. A sample is provided here: TSS CREATE(MV$CAS) TYPE(USER) - NAME('CAS, BMC Mainview for z/OS') DEPT(xxxx) - FAC(STC,BBI3) - MASTFAC(BBI3) PASS(xxxxxxxx,0) - SOURCE(INTRDR) NOSUSPEND TSS CREATE(MV$PAS) TYPE(USER) - NAME('PAS, BMC Mainview for z/OS') DEPT(xxxx) - FAC(STC,BBI3) - MASTFAC(BBI3) PASS(xxxxxxxx,0) - SOURCE(INTRDR) NOSUSPEND TSS CREATE(MV$MVS) TYPE(USER) - NAME('MVS, BMC Mainview for z/OS') DEPT(xxxx) - FAC(STC,BBI3) - PASS(xxxxxxxx,0) - SOURCE(INTRDR) NOSUSPEND

Discussion

BMC Mainview for z/OS requires a started task that will be restricted to certain resources, datasetsdata sets, 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.

Fix text

The BMC Mainview for z/OS systemsystems programmer and the IAOISSO will ensure that a product's started task(s) is (are) properly identified and/or defined to the Systemsystem ACP. A unique ACID must be assigned for the BMC Mainview for z/OS started task(s) thruthrough a corresponding STC table entry. The following sample set of commands is shown here as a guideline: TSS ADD(STC) PROCNAME(MV$CAS) ACID(MV$CAS) TSS ADD(STC) PROCNAME(MV$MVS) ACID(MV$MVS)

Discussion

Access to product resources should be restricted to only those individuals responsible for the application connectivity and who have a requirement to access these resources. Improper control of product resources could potentially compromise the operating system, ACP, and customer data.
