Compuware Abend-AID 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-25963r519797_chk

Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(AIDRPT) Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZAID0000) Verify that the accesses to the Compuware Abend-AID 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 all authorized 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 is logged.

Fix: F-25951r519798_fix

The IAO will ensure that WRITE and/or greater access to Compuware Abend-AID installation data sets is limited to System 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 data sets and categorize them according to who will have WRITE and/or greater access and if required that all WRITE and/or greater access is logged. He will identify if any additional groups have WRITE and/or greater 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. Data sets to be protected will be: SYS2.ABENDAID. SYS2A.ABENDAID. SYS3A.ABENDAID. The following commands are provided as a sample for implementing data set controls: $KEY(S2A) $PREFIX(SYS2) ABENDAID.V-.- UID(syspaudt) R(A) W(L) A(L) E(A) ABENDAID.V-.- UID(authorized users/*) R(A) E(A) SET RULE COMPILE 'ACF2.MVA.DSNRULES(S2A)' STORE $KEY(SYS2A0A) $MODE(ABORT) $PREFIX(SYS2A) ABENDAID.V-.- UID(syspaudt) R(A) W(L) A(L) E(A) ABENDAID.V-.- UID(authorized users/*) R(A) E(A) SET RULE COMPILE 'ACF2.MVA.DSNRULES(SYS2A0A)' STORE $KEY(SYS3A0A) $PREFIX(SYS3A) ABENDAID.V-.- UID(syspaudt) R(A) W(L) A(L) E(A) ABENDAID.V-.- UID(authorized users/*) R(A) E(A) SET RULE COMPILE 'ACF2.MVA.DSNRULES(SYS3A0A)' STORE

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

Refer to the following report produced by the ACF2 Data Collection and Data Set and Resource Data Collection: - SENSITVE.RPT(ZAID0020) - ACF2CMDS.RPT(RESOURCE) - Alternate report Automated Analysis Refer to the following report produced by the Data Set 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: F-25954r868076_fix

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 actually 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
