BMC CONTROL-O 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-26087r1070126_chk

Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(CTORPT) Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZCTO0000) Verify that the accesses to the BMC CONTROL-O installation data sets are properly restricted. If the following guidance is true, this is not a finding. The RACF data set rules for the data sets restricts READ access to auditors, BMC users, and BMC STCs and/or batch users. The RACF data set rules for the data sets restricts WRITE and/or greater access to systems programming personnel. The RACF data set rules for the data sets specify that all (i.e., failures and successes) WRITE and/or greater access are logged. The RACF data set rules for the data sets specify UACC(NONE) and NOWARNING.

Fix: F-26075r1070127_fix

The ISSO will ensure that WRITE and/or greater access to BMC CONTROL-O installation data sets are limited to systems programmers only, and all WRITE and/or greater access is logged. READ access can be given to auditors, BMC users, 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 update and alter access and if required that all update and allocate access is logged. The installing systems programmer will identify if any additional groups have update and/or alter 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.) Data sets to be protected will be: SYS2.IOA.*.CTOI. The following commands are provided as a sample for implementing data set controls: ad 'SYS2.IOA.*.CTOI.**' uacc(none) owner(sys2) - audit(success(update) failures(read)) - data('Vendor DS Profile: BMC CONTROL-O') pe 'SYS2.IOA.*.CTOI.**' id(<syspaudt>) acc(a) pe 'SYS2.IOA.*.CTOI.**' id(<audtaudt> <bmcuser>) acc(r) pe 'SYS2.IOA.*.CTOI.**' id(CONTROLO) acc(r) setr generic(dataset) refresh

BMC CONTROL-O 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 nonsystems personnel with read only authority.

Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(ZCTO0020) Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZCTO0020) Verify that the accesses to resources and/or generic equivalent are properly restricted according to the requirements specified in BMC CONTROL-O 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 RACF resources are defined with a default access of NONE. The RACF resource access authorizations restrict access to the appropriate personnel. The RACF resource logging requirements are specified. The RACF resource access authorizations are defined with UACC(NONE) and NOWARNING.

Fix: F-26077r1070160_fix

The ISSO will work with the systems programmer to verify that the following are properly specified in the Access Control Program (ACP). Note: To determine what resource class is used review the IOACLASS setting in SECPARM. The "Trigger" resources i.e., $$SECxxx (xxx is unique to the product) are defined in the FACILITY resource class (Note: The resource class, resources, and/or resource prefixes identified below are examples of a possible installation. The actual resource class, resources, and/or resource prefixes are determined when the product is actually installed on a system through the product's installation guide and can be site specific.) Use BMC CONTROL-O Resources and BMC INCONTROL Resources Descriptions tables in the z/OS STIG Addendum. These tables list the resources, descriptions, and access and logging requirements. Ensure the guidelines for the resources and/or generic equivalent specified in the z/OS STIG Addendum are followed. The following commands are provided as a sample for implementing resource controls: $key($$ctoaop) type(ioa) - uid(<operaudt>) log - uid(<pcspaudt>) log - uid(<prodaudt>) log - uid(<syspaudt>) log - uid(*) prevent

BMC CONTROL-O 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-26090r518854_chk

Refer to the following report produced by the RACF Data Collection: - RACFCMDS.RPT(LISTUSER) The BMC CONTROL-O started task(s) and/or batch job userid(s) is defined and is assigned the RACF PROTECTED attribute.

Fix: F-26078r518855_fix

The BMC CONTROL-O system programmer and the IAO 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. A sample is provided here: au CONTROLO name('stc, BMC CONTROL-O') owner(stc) dfltgrp(stc) nopass
