This Security Technical Implementation Guide is published as a tool to improve the security of Department of Defense (DOD) information systems. The requirements are derived from the National Institute of Standards and Technology (NIST) 800-53 and related documents.

CA Auditor 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.
Checks: C-25938r1141319_chk

Refer to the following report produced by the dataset and Resource Data Collection: - SENSITVE.RPT(ADTRPT). Automated Analysis Refer to the following report produced by the dataset and Resource Data Collection: - PDI(ZADT0000). Verify that the accesses to the CA Auditor 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 auditors, security administrators, and/or CA Auditor's STCs and batch 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: F-25926r1141320_fix

The ISSO will ensure that WRITE and/or greater access to CA Auditor installation datasets is limited to systems programmers only, and all WRITE and/or greater access is logged. READ access can be given to auditors, security administrators, and/or CA Auditor's STCs and batch 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 they are properly restricted to the ACP (Access Control Program) active on the system. Datasets to be protected will be: SYS2.EXAMINE SYS2A.EXAMINE The following commands are provided as a sample for implementing dataset controls: $KEY(SYS2) EXAMINE.- UID(<syspaudt>) R(A) W(L) A(L) E(A) EXAMINE.- UID(<audtaudt>) R(A) E(A) EXAMINE.- UID(<secaaudt>) R(A) E(A) EXAMINE.- UID(EXAMMON) R(A) E(A) $KEY(SYS2A) EXAMINE.- UID(<syspaudt>) R(A) W(L) A(L) E(A) EXAMINE.- UID(<audtaudt>) R(A) E(A) EXAMINE.- UID(<secaaudt>) R(A) E(A) EXAMINE.- UID(EXAMMON) R(A) E(A)

CA Auditor User 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.

Refer to the following report produced by the dataset and Resource Data Collection: - SENSITVE.RPT(ADTUSER). Automated Analysis Refer to the following report produced by the dataset and Resource Data Collection: - PDI(ZADT0002). Verify that the accesses to the CA Auditor User datasets are properly restricted. If the following guidance is true, this is not a finding. The ACF2 dataset rules for the datasets restrict WRITE and/or greater access to systems programming personnel, security personnel, and auditors.

Fix: F-25927r1141323_fix

The ISSO will ensure that WRITE and/or greater access to CA Auditor User datasets is limited to systems programmers, security personnel, and auditors. 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 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. Datasets to be protected will be: dataasets SYS3.EXAMINE The following commands are provided as a sample for implementing dataset controls: $KEY(SYS3) EXAMINE.- UID(<syspaudt>) R(A) W(A) A(A) E(A) EXAMINE.- UID(<audtaudt>) R(A) W(A) A(A) E(A) EXAMINE.- UID(<secaaudt>) R(A) W(A) A(A) E(A)

CA Auditor 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 non systems personnel with read only authority.
Checks: C-25940r1141325_chk

Refer to the following report produced by the dataset and Resource Data Collection: - SENSITVE.RPT(ZADT0020). - ACF2CMDS.RPT(RESOURCE) - Alternate report. Automated Analysis Refer to the following report produced by the dataset and Resource Data Collection: - PDI(ZADT0020). Verify that the access to the LTDMMAIN resource in the PROGRAM resource class is restricted. If the following guidance is true, this is not a finding. The ACF2 rules for the resources specify a default access of NONE. The ACF2 rules for the resources are restricted access to systems programmers, auditors, and security personnel.

Fix: F-25928r1041185_fix

The IOA will verify that the LTDMMAIN resource in the PROGRAM resource class is restricted to systems programmers, auditors, and security personnel. The ACF2 rules for the resource specify a default access of NONE. There are ACF2 rules defined and only systems programmers, auditors, and security personnel have access. Example: SET R(PGM) $KEY(LTDMMAIN) TYPE(PGM) UID(<syspaudt>) ALLOW UID(<audtaudt>) ALLOW UID(<secaaudt>) ALLOW UID(*) PREVENT DATA(SRR FINDING FOR CA AUDITOR)
