Fix text

The systemsystems programmer responsible for the BMC IOA will review the BMC IOA operating environment. Ensure that the following security exit(s) is (are) installed properly. Determine if the site has modified the following security exit(s): IOASE06 IOASE07 IOASE09 IOASE12 IOASE16 IOASE32 IOASE40 IOASE42 Ensure that the security exit(s) has (have) not been modified. If the security exit(s) has (have) been modified, ensure the security exit(s) has (have) been checked as to not violate any security integrity within the system and approval documentation is on file.

Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZIOA0000). Verify that the accesses to the BMC IOA installation data sets are properly restricted. If the following guidance is true, this is not a finding. The TSS data set access authorizations restrict READ access to auditors, BMC users, operations, production control and scheduling personnel, and BMC STCs and/or batch users. The TSS data set access authorizations restrict WRITE and/or greater access to systems programming personnel. The TSS data set access authorizations specify that all (i.e., failures and successes) WRITE and/or greater access are logged.

Fix text

The ISSO will ensure that WRITE and/or greater access to BMC IOA installation data sets are limited to systems programmers only. READ access can be given to auditors, BMC users, operations, production control and scheduling personnel, 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 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. (Note: The data sets and/or data set prefixes identified below are examples of a possible installation. The actual data sets 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.)

Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZIOA0020). Verify that the accesses to resources and/or generic equivalent are properly restricted according to the requirements specified in BMC IOA 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 TSS resources are owned or DEFPROT is specified for the resource class. The TSS resource access authorizations restrict access to the appropriate personnel. The TSS resource logging requirements are specified.

Refer to the following report produced by the TSS Data Collection: - TSSCMDS.RPT(@ACIDS). VerifyReview that the ACID(s) for the BMC IOA startedSTC/Batch taskACID(s) is (are) properly defined. If the following attributes are defined, this is not a finding. FACILITY(STC, BATCH) PASSWORD(xxxxxxxx,0) MASTFAC(IOA) SOURCE(INTRDR) NOSUSPEND MASTFAC(IOA)

Fix text

The IAOISSO working with the systems programmer will ensure the BMC IOA Started Task(s) is (are) 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. The following commands are provided as a sample for defining Started Task(s): TSS CREATE(IOAGATE) TYPE(USER) - NAME('*STC* for IOA') DEPT(xxxx) - FAC(STC,BATCH) - MASTFAC(IOA) PASS(xxxxxxxx,0) - SOURCE(INTRDR) NOSUSPEND

Discussion

BMC IOA 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 IOA 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 IOA 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(IOAGATE) ACID(IOAGATE)

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.
