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 text

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 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.) 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(&ltsyspaudt>) acc(a) pe 'SYS2.IOA.*.CTOI.**' id(&ltaudtaudt> &ltbmcuser>) acc(r) pe 'SYS2.IOA.*.CTOI.**' id(CONTROLO) acc(r) setr generic(dataset) refresh

The ISSO will ensure that WRITE and/or greater access to BMC CONTROL-O STC data sets are limited to System Programmers only. UPDATE access can be given to BMC users and the BMC STCs and/or batch users. READ access can be given to auditors, operators, and domain level production control and scheduling personnel. The installing systems programmer will identify and document the product data sets and categorize them according to who will have what type of access and if required which type of access is logged. The installing systems programmer will identify any additional groups requiring access to specific data sets, and once documented the installing systems programmer will work with the ISSO to see that they are properly restricted to the ACP (Access Control Program) active on the system. Data sets to be protected will be: SYS3.IOA.*.CTOO.** The following commands are provided as a sample for implementing data set controls: ad 'SYS3.IOA.*.CTOO.**' uacc(none) owner(sys3) - audit(failures(read)) - data('BMC CONTROL-O Operational & Repository') pe 'SYS3.IOA.*.CTOO.**' id(&ltsyspaudt>) acc(a) pe 'SYS3.IOA.*.CTOO.**' id(CONTROLO) acc(u) pe 'SYS3.IOA.*.CTOO.**' id(&ltbmcuser> &ltbmcbatch>) acc(u) pe 'SYS3.IOA.*.CTOO.**' id(&ltaudtaudt>) acc(r) pe 'SYS3.IOA.*.CTOO.**' id(&ltoperaudt>) acc(r) pe 'SYS3.IOA.*.CTOO.**' id(&ltpcspaudt>) acc(r) setr generic(dataset) refresh

Discussion

BMC CONTROL-O STC 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.

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 text

The BMC CONTROL-O system programmer and the IAOISSO 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

Discussion

BMC CONTROL-O 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 CONTROL-O system programmer and the IAOISSO will ensure that a product's started task(s) is (are) properly identified and/or defined to the System ACP. A unique userid must be assigned for the BMC CONTROL-O started task(s) thru a corresponding STARTED class entry. The following sample set of commands is shown here as a guideline: rdef started CONTROLO.** uacc(none) owner(admin) audit(all(read)) stdata(user(CONTROLO) group(stc)) setr racl(started) ref

Discussion

Access to product resources shouldmust 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.
