BMC CONTROL-D configuration/parameters control 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.

The BMC CONTROL-D security exits enable access authorization checking to BMC CONTROL-D commands, features, and online functionality. If these exit(s) is (are) not in place, activities by unauthorized users may result. BMC CONTROL-D security exit(s) interface with the ACP. If an unauthorized exit was introduced into the operating environment, system security could be weakened or bypassed. These exposures may result in the compromise of the operating system environment, ACP, and customer data.
Checks: C-25780r1041232_chk

Interview the systems programmer responsible for the BMC CONTROL-D. Determine if the site has modified the following security exit(s): CTDSE01 CTDSE04 CTDSE08 CTDSE19 CTDSE24 CTDSE28 Ensure the above security exit(s) has (have) not been modified. If the above security exit(s) has (have) been modified, ensure that the security exit(s) has (have) been approved by the site systems programmer and the approval is on file for examination.

Fix: F-25768r1041233_fix

The systems programmer responsible for the BMC CONTROL-D will review the BMC CONTROL-D operating environment. Ensure that the following security exit(s) is (are) installed properly.

BMC CONTROL-D installation datasets have the ability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to these datasets could result in violating the integrity of the base product which could result in compromising the operating system or sensitive data.
Checks: C-25781r1141433_chk

Refer to the following report produced by the dataset and Resource Data Collection: - SENSITVE.RPT(CTDRPT). Automated Analysis Refer to the following report produced by the dataset and Resource Data Collection: - PDI(ZCTD0000). Verify that the accesses to the BMC CONTROL-D installation datasets are properly restricted. If the following guidance is true, this is not a finding. The ACF2 dataset access authorizations restrict READ access to auditors, BMC users, security personnel (domain level and decentralized), and BMC STCs and/or batch users. The ACF2 dataset access authorizations restrict WRITE and/or greater access to systems programming personnel. The ACF2 dataset access authorizations specify that all (i.e., failures and successes) WRITE and/or greater access is logged.

Fix: F-25769r1141434_fix

The ISSO will ensure that WRITE and/or greater access to BMC CONTROL-D installation datasets is limited to systems programmers only, and all WRITE and/or greater access is logged. READ access can be given to auditors, BMC users, security personnel (domain level and decentralized), and BMC STCs and/or batch users. All failures and successful WRITE and/or greater accesses are logged. The installing systems programmer will identify and document the product datasets, 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 datasets, and once documented will work with the ISSO to ensure they are properly restricted to the ACP (Access Control Program) active on the system. (Note: The datasets and/or dataset prefixes identified below are examples of a possible installation. The actual datasets and/or prefixes are determined when the product is installed on a system through the product's installation guide and can be site specific.)

BMC CONTROL-D 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.

Refer to the following report produced by the dataset and Resource Data Collection: - SENSITVE.RPT(ZCTD0020). - ACF2CMDS.RPT(RESOURCE) - Alternate report. Automated Analysis Refer to the following report produced by the dataset and Resource Data Collection: - PDI(ZCTD0020). Verify that the accesses to resources and/or generic equivalent are properly restricted according to the requirements specified in BMC CONTROL-D Resources table in the z/OS STIG Addendum. If the following guidance is true, this is not a finding. Note: To determine what resource class is used review the IOACLASS setting in SECPARM. The "Trigger" resources, i.e., $$SECxxx (xxx is unique to the product) are defined in the FACILITY resource class The ACF2 resources are defined with a default access of PREVENT. The ACF2 resource access authorizations restrict access to the appropriate personnel. The ACF2 resource logging requirements are specified.

Fix: F-25772r1141443_fix

The ISSO will work with the systems programmer to verify that the following are properly specified in the ACP. Note: To determine what resource class is used review the IOACLASS setting in SECPARM. The "Trigger" resources, i.e., $$SECxxx (xxx is unique to the product) are defined in the FACILITY resource class (Note: The resource class, resources, and/or resource prefixes identified below are examples of a possible installation. The actual resource class, resources, and/or resource prefixes are determined when the product is installed on a system through the product's installation guide and can be site specific.) Use BMC CONTROL-D Resources and BMC INCONTROL Resources Descriptions tables in the zOS STIG Addendum. These tables list the resources, descriptions, and access and logging requirements. Ensure the guidelines for the resources and/or generic equivalent specified in the z/OS STIG Addendum are followed.

BMC CONTROL-D requires a started task that will be restricted to certain resources, datasets, 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.

Fix: F-25773r1141446_fix

The BMC CONTROL-D systems programmer and the ISSO will ensure that a product's Started Task(s) is properly Identified / 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 CHANGE CONTROLD STC MUSASS NO-SMC
