Vuln_Discuss Compuware Abend-AID offers external security interfaces that are controlled by parameters specified in FDBDPARM DD statement of the started task procedures. These interfaces provide security controls for Abend-AID. Without proper controls to ensure that security is active, the integrity of the Compuware Abend-AID System and the confidentiality of data stored on the system may be compromised. Check_Content Examine the Enterprise Common Components (ECC) started task procedure. (This can usually be found in the system PROCLIBs). Refer to the contents of the data set specified in the CWPARM DD statement. Automated Analysis Refer to the following report produced by the z/OS Data Collection: - PDI(ZAID0040) Review the Member name listed.

Vuln_Discuss Compuware Abend-AID 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. Check_Content Refer to the following report produced by the dataset and Resource Data Collection: - SENSITVE.RPT(AIDRPT). Automated Analysis Refer to the following report produced by the dataset and Resource Data Collection: - PDI(ZAID0000). Verify that the accesses to the Compuware Abend-AID installation datasets are properly restricted. If the following guidance is true, this is not a finding. The ACF2 dataset rules for the datasets restrict READ access to all authorized users. The ACF2 dataset rules for the datasets restrict WRITE and/or greater access to systems programming personnel. The ACF2 dataset rules for the datasets specify that all (i.e., failures and successes) WRITE and/or greater access is logged. Fix_Text The ISSO will ensure that WRITE and/or greater access to Compuware Abend-AID installation datasets is limited to systems programmers only, and all WRITE and/or greater access is logged. READ access can be given to all authorized users. 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 that they are properly restricted to the ACP (Access Control Program) active on the system.

Vuln_Discuss Compuware Abend-AID 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. Check_Content Refer to the following report produced by the ACF2 Data Collection and dataset and Resource Data Collection: - SENSITVE.RPT(ZAID0020). - ACF2CMDS.RPT(RESOURCE) - Alternate report. Automated Analysis Refer to the following report produced by the dataset and Resource Data Collection: - PDI(ZAID0020). Note: The Abend-AID resource class is identified in the Enterprise Common Components (ECC) STC procedure, CWPARM DD statement, member name AAVW00, using the parameter setting EXTERNAL_SECURITY_RESOURCE_CLASS. Verify that the accesses to resources and/or generic equivalent are properly restricted according to the requirements specified in the Compuware Abend-AID Resources table in the z/OS STIG Addendum. If the following guidance is true, this is not a finding. The ACF2 resources are defined with a default access of PREVENT. The ACF2 resource access authorizations restrict access to the appropriate personnel. Fix_Text Ensure that the following are properly specified in the ACP. (Note: The resources and/or resource prefixes identified below are examples of a possible installation. The actual resources and/or prefixes are determined when the product is installed on a system through the product's installation guide and can be site specific.) Use the Compuware Abend-AID Resources and Compuware Abend-AID Resources Descriptions tables in the zOS STIG Addendum. These tables list the resources, access requirements, and logging requirement for Compuware Abend-AID. Ensure the guidelines for the resources and/or generic equivalent specified in the z/OS STIG Addendum are followed. Note: The Compuware Abend-AID resource class is identified in the Viewer Server's STC configuration procedure, CWPARM DD statement, member name AAVW00, using the parameter setting EXTERNAL_SECURITY_RESOURCE_CLASS. In addition, there is a parameter that identifies the prefix for all resources, which is EXTERNAL_SECURITY_PREFIX. The ACF2 resources as designated in the above table are defined with a default access of PREVENT. The ACF2 resource access authorizations restrict access to the appropriate personnel as designated in the above table. The following commands are provided as a sample for implementing resource controls: $KEY(prefix) TYPE(resource-type) SERVER.LOGON.FD.- UID(appdaudt) ALLOW SERVER.LOGON.FD.- UID(appsaudt) ALLOW SERVER.LOGON.FD.- UID(operaudt) ALLOW SERVER.LOGON.FD.- UID(syspaudt) ALLOW - UID(*) PREVENT Not_Reviewed Vuln_Num V-224294 Rule_ID SV-224294r1144191_rule Severity medium Rule_Title Compuware Abend-AID Started Task name will be properly identified and/or defined to the system ACP. Vuln_Discuss Compuware Abend-AID 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. Check_Content Refer to the following report produced by the ACF2 Data Collection: - ACF2CMDS.RPT(ATTSTC). Verify that the logonid(s) for the Compuware Abend-AID started task(s) is (are) properly defined. If the following attributes are defined, this is not a finding. STC Fix_Text The ISSO working with the systems programmer will ensure the Compuware Abend-AID Started Task(s) is properly identified and/or 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. The following commands are provided as a sample for defining Started Task(s): SET LID insert AAVIEWER stc name('STC, Compuware Abend-AID Viewer') insert BDCAS stc name('STC, Compuware Abend-AID') insert TDCAS stc name('STC, Compuware Abend-AID for CICS') Not_Reviewed
