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-25923r518959_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. ___ The ACF2 data set rules for the data sets restricts READ access to all authorized users. ___ The ACF2 data set rules for the data sets restricts UPDATE and/or ALTER access to systems programming personnel. ___ The ACF2 data set rules for the data sets specify that all (i.e., failures and successes) UPDATE and/or ALTER access are logged.

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: $KEY(SYS2) BMCVIEW.- UID(<syspaudt>) R(A) W(L) A(L) E(A) BMCVIEW.- UID(<tstcaudt>) R(A) W(L) A(L) E(A) BMCVIEW.- UID(<audtaudt>) R(A) E(A) BMCVIEW.- UID(authorized users) R(A) E(A) BMCVIEW.- UID(<audtaudt>) R(A) E(A) BMCVIEW.- UID(MAINVIEW STCs) R(A) E(A) $KEY(SYS3) BMCVIEW.- UID(<syspaudt>) R(A) W(L) A(L) E(A) BMCVIEW.- UID(<tstcaudt>) R(A) W(L) A(L) E(A) BMCVIEW.- UID(<audtaudt>) R(A) E(A) BMCVIEW.- UID(authorized users) R(A) E(A) BMCVIEW.- UID(MAINVIEW STCs) R(A) E(A)

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.

Refer to the following report produced by the ACF2 Data Collection and Data Set and Resource Data Collection: - SENSITVE.RPT(ZMVZ0020) - ACF2CMDS.RPT(RESOURCE) - Alternate report 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 ACF2 resources are defined with a default access of PREVENT. ___ The ACF2 resource access authorizations restrict access to the appropriate personnel.

Fix: F-25913r868208_fix

The ISSO will work with the systems programmer to verify that the following are properly specified in the ACP. (Note: The resource type, resources, and/or resource prefixes identified below are examples of a possible installation. The actual resource type, 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 resource type, resources, and/or generic equivalent specified in the z/OS STIG Addendum are followed. The ACF2 resources as designated in the above table are defined with a default access of PREVENT. The ACF2 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: $KEY(BBM) TYPE(BMV) ssid.CN UID(autoaudt) ALLOW ssid.CN UID(dasdaudt) ALLOW ssid.CN UID(mqsaaudt) ALLOW ssid.CN UID(Mainview STCs) ALLOW ssid.CN UID(mvzread) ALLOW ssid.CN UID(mvzupdt) ALLOW ssid.CN UID(pcspaudt) ALLOW ssid.CN UID(syspaudt) ALLOW - UID(*) PREVENT

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.
Checks: C-25926r518968_chk

Refer to the following report produced by the ACF2 Data Collection: - ACF2CMDS.RPT(ATTSTC) Insure that the logonids(s) for the BMC Mainview for z/OS started task(s) includes the following: STC NO-SMC

Fix: F-25914r518969_fix

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. Example: SET LID INSERT MV$CAS STC NO-SMC INSERT MV$PAS STC NO-SMC INSERT MV$MVS STC NO-SMC

BMC MAINVIEW for z/OS configuration/parameters controls the security and operational characteristics of products. If these parameter values are improperly specified, security and operational controls may be weakened. This exposure may threaten the availability of the product applications, and compromise the confidentiality of customer data.
Checks: C-25928r518974_chk

Refer to the Configuration Location dataset and member specified in the z/OS Dialog Management Procedures for BMC MAINVIEW for z/OS. Automated Analysis Refer to the following report produced by the z/OS Data Collection: - PDI(ZMVZ0040) The following keywords will have the specified values in the BMC MAINVIEW for z/OS security parameter member: Statement(values) ESMTYPE(AUTO|ACF2)

Fix: F-25916r518975_fix

The BMC MAINVIEW for z/OS Systems programmer will verify that any configuration/parameters that are required to control the security of the product are properly configured and syntactically correct. Set the standard values for the BMC MAINVIEW for z/OS security parameters for the specific ACP environment along with additional IOA security parameters with standard values as documented below.
