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.
Checks: C-26290r1146069_chk

Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(MVZRPT). 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 restrict READ access to all authorized users. The TSS data set rules for the data sets restrict WRITE and/or greater access to systems programming personnel. The TSS data set rules for the data sets specify that all (i.e., failures and successes) WRITE and/or greater access are logged.

Fix: F-26278r1146356_fix

The ISSO will ensure that WRITE and/or greater access to BMC MAINVIEW for z/OS installation data 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 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 WRITE and/or greater 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 (Data sets that are not altered by product STCs; this 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 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 systems programmers only in greater than read authority. Resources are also granted to certain non systems personnel with read only authority.
Checks: C-26292r1146075_chk

Refer to the following reports 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-26280r1070244_fix

The ISSO will work with the systems programmer to verify that the following are properly specified in the Access Control Program (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)

BMC Mainview for z/OS requires a started task that will be restricted to certain resources, data sets, and other system functions. Defining the started task as a userid to the system ACP allows the ACP to control the access and authorized users that require these capabilities. Failure to properly control these capabilities could compromise the operating system environment, ACP, and customer data.
Checks: C-26293r1146077_chk

Refer to the following report produced by the TSS Data Collection: - TSSCMDS.RPT(@ACIDS). Review BMC Mainview for z/OS STC/Batch ACID(s). If the following attributes are defined, this is not a finding. For MV$CAS and MV$PAS FACILITY(STC, BBI3) PASSWORD(xxxxxxxx,0) SOURCE(INTRDR) NOSUSPEND MASTFAC(BBI3) For MV$MVS FACILITY(STC, BBI3) PASSWORD(xxxxxxxx,0) SOURCE(INTRDR) NOSUSPEND

Fix: F-26281r1146078_fix

The BMC Mainview for z/OS systems programmer and the ISSO 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

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.
Checks: C-26294r1146080_chk

Refer to the following report produced by the TSS Data Collection: - TSSCMDS.RPT(#STC). Automated Analysis Refer to the following report produced by the TSS Data Collection: - PDI(ZMVZ0032). If the BMC Mainview for z/OS started task(s) is (are) defined in the TSS STC record, this is not a finding.

The ISSO will ensure the BMC Mainview for z/OS resource class(es) is (are) defined in the TSS RDT. (Note: The RESCLASS and/or RESCODE identified below are examples of a possible installation. The actual RESCLASS and/or RESCODE values are determined when the product is actually installed on a system through the product's installation guide and can be site specific.) Use the following commands as an example: TSS ADDTO(RDT) RESCLASS(BMCVIEW) - RESCODE(3B) DEFACC(READ) - ATTR(MASK|NOMASK,DEFPROT,LONG,GENERIC) - ACLST(NONE,READ,UPDATE,ALL)
