BMC MAINVIEW for z/OS installation data sets have the ability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to these data sets could result in violating the integrity of the base product which could result in compromising the operating system or sensitive data.Information Assurance OfficerSystems ProgrammerDCSL-1, ECAR-1, ECAR-2, ECCD-1, ECCD-2

The IAO will ensure that update and allocate access to BMC MAINVIEW for z/OS installation data sets is limited to System Programmers only, and all update and allocate access is logged. 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 update and alter access and if required that all update and allocate access is logged. He will identify if any additional groups have update and/or alter 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 sets to be protected will be: SYS2.BMCVIEW. SYS3.BMCVIEW. (data sets that are not altered by product STCs, can be more specific) The following commands are provided as a sample for implementing data set controls: TSS PERMIT(<syspaudt>) DSN(SYS2.BMCVIEW.)

BMC Mainview for z/OS requires a started task that will be restricted to certain resources, datasets and other system functions. By 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.Information Assurance OfficerECCD-1, ECCD-2

The BMC Mainview for z/OS system programmer and the IAO will ensure that a product's 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 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

BMC MAINVIEW can run with sensitive system privileges, and potentially can circumvent system controls. Failure to properly control access to product resources could result in the compromise of the operating system environment, and compromise the confidentiality of customer data. Many utilities assign resource controls that can be granted to system programmers only in greater than read authority. Resources are also granted to certain non systems personnel with read only authority.Information Assurance OfficerSystems ProgrammerECCD-1, ECCD-2
Checks: C-6205r2_chk

Refer to the following report produced by the TSS Data Collection and Data Set and Resource Data Collection: - SENSITVE.RPT(ZMVZ0020) - TSSCMDS.RPT(#RDT) Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZMVZ0020) Verify that the accesses to resources and/or generic equivalent are properly restricted according to the requirements specified in BMC MAINVIEW Resources table in the z/OS STIG Addendum. 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.

Fix: F-18741r4_fix

The IAO will work with the systems programmer to verify that the following are properly specified in the ACP. (Note: The resource class, resources, and/or resource prefixes identified below are examples of a possible installation. The resource class, actual resources, and/or prefixes are determined when the product is actually installed on a system through the product’s installation guide and can be site specific.) Use BMC MAINVIEW Resources table in the zOS STIG Addendum. This table lists the resources, access requirements, and logging requirement for BMC MAINVIEW. Ensure the guidelines for the resources and/or generic equivalent specified in the z/OS STIG Addendum are followed. The TSS resources as designated in the above table are owned and/or DEFPROT is specified for the resource class. The TSS resource access authorizations restrict access to the appropriate personnel as designated in the above table. The following commands are provided as a sample for implementing resource controls: TSS ADD(dept-acid) #BMCVIEW(BBM) TSS PERMIT(autoaudt) #BMCVIEW(BBM.ssid.CN) ACCESS(ALL) TSS PERMIT(dasdaudt) #BMCVIEW(BBM.ssid.CN) ACCESS(ALL) TSS PERMIT(mqsaaudt) #BMCVIEW(BBM.ssid.CN) ACCESS(ALL) TSS PERMIT(Mainview STCs) #BMCVIEW(BBM.ssid.CN) ACCESS(ALL) TSS PERMIT(mvzread) #BMCVIEW(BBM.ssid.CN) ACCESS(ALL) TSS PERMIT(mvzupdt) #BMCVIEW(BBM.ssid.CN) ACCESS(ALL) TSS PERMIT(pcspaudt) #BMCVIEW(BBM.ssid.CN) ACCESS(ALL) TSS PERMIT(syspaudt) #BMCVIEW(BBM.ssid.CN) ACCESS(ALL)
