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.Information Assurance OfficerSystems Programmer
Checks: C-3238r2_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 ACF2 data set rules for the data sets restricts READ access to auditors, BMC users, and BMC STCs and/or batch users. ___ The ACF2 data set rules for the data sets restricts WRITE and/or greater access to systems programming personnel. ___ The ACF2 data set rules for the data sets specify that all (i.e., failures and successes) WRITE and/or greater access are logged.

Fix: F-3831r5_fix

The IAO will ensure that WRITE and/or greater access to BMC CONTROL-O installation data sets are limited to System 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. 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. (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: $KEY(SYS2) IOA.-.CTOI.- UID(<syspaudt>) R(A) W(L) A(L) E(A) IOA.-.CTOI.- UID(<audtaudt>) R(A) E(A) IOA.-.CTOI.- UID(<bmcuser>) R(A) E(A) IOA.-.CTOI.- UID(CONTROLO) R(A) E(A)

Fix: F-6843r5_fix

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. (Note: The data sets and/or data set prefixes identified below are examples of a possible installation.

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.Information Assurance Officer
Checks: C-342r1_chk

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

Fix: F-296r1_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. Example: SET LID CHANGE CONTROLO STC MUSASS NO-SMC

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 system programmers only in greater than read authority. Resources are also granted to certain non systems personnel with read only authority.Information Assurance OfficerSystems Programmer

Refer to the following report produced by the ACF2 Data Collection and Data Set and Resource Data Collection: - SENSITVE.RPT(ZCTO0020) - ACF2CMDS.RPT(RESOURCE) – Alternate report 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 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-349r6_fix

The IAO 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., $$SECxxx (xxx is unique to the product) are defined in the FACILITY resource class (Note: The resource class, resources, and/or resource prefixes identified below are examples of a possible installation. The actual resource class, resources, and/or resource prefixes are determined when the product is actually installed on a system through the product’s installation guide and can be site specific.) Use BMC CONTROL-O Resources and BMC INCONTROL Resources Descriptions tables in the zOS STIG Addendum. These tables list the resources, descriptions, and access and logging requirements. Ensure the guidelines for the resources and/or generic equivalent specified in the z/OS STIG Addendum are followed. The following commands are provided as a sample for implementing resource controls: $key($$ctoaop) type(ioa) - uid(<operaudt>) log - uid(<pcspaudt>) log - uid(<prodaudt>) log - uid(<syspaudt>) log - uid(*) prevent

The BMC CONTROL-O security exits enable access authorization checking to BMC CONTROL-O commands, features, and online functionality. If these exit(s) is (are) not in place, activities by unauthorized users may result. BMC CONTROL-O 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.Information Assurance OfficerSystems Programmer

Determine if the site has modified the following security exit(s): CTOSE01 CTOSE02 CTOSE03 CTOSE04 CTOSE08 CTOSE10 CTOSE15 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-305r1_fix

The System programmer responsible for the BMC CONTROL-O will review the BMC CONTROL-O operating environment. Ensure that the following security exit(s) is (are) installed properly. Determine if the site has modified the following security exit(s): CTOSE01 CTOSE02 CTOSE03 CTOSE04 CTOSE08 CTOSE10 CTOSE15 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.
