Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(CA1PROD) Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZCA10000) Verify that the accesses to the CA 1 Tape Management installation data sets are properly restricted. If the following guidance is true, this is not a finding. ___ The TSS data set rules for the data sets restricts READ access to all authorized users. ___ The TSS data set rules for the data sets restricts WRITE and/or greater access to systems programming personnel. ___ The TSS data set rules for the data sets specify that all (i.e., failures and successes) WRITE and/or greater access is logged.

Fix: F-23637r2_fix

Ensure that WRITE and/or greater access to CA 1 Tape Management 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. The following is an example of the type of data sets to be protected: SYS2.CA1. SYS2A.CA1.*.CAILIB SYS2A.CA1.*.CAILPA Or SYS2A.CA1.*.CTAPLINK SYS3.CA1.

Fix: F-6623r5_fix

The IAO will ensure that WRITE and/or greater access to CA 1 TMC, AUDIT and optional RDS and VPD data sets are limited to only systems programming personnel and tape management personnel. UPDATE access can be given to CA 1 STCs and/or batch users. READ access can be given to application support personnel, production control and scheduling personnel, operations personnel, and auditors. ALL access will be 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.) Due to the unique file structure of the TMC and Audit data sets, CA 1 uses the YSVC programs to handle all direct I/O activity. Because standard OPEN/CLOSE macros are not used, typical data set security checks are not performed. Even if a user does not have read authority to these data sets, the YSVC programs can enable that user to read and update records within these files. Therefore, control READ access to the TMC and Audit data sets by the YSVCUNCD and YSVCCOND resource names. Typical users should be restricted to conditional READ access. Restrict CA 1 batch production jobs, and CA 1 started tasks to the following access authority: Unconditional READ and UPDATE access to the TMC, Audit, Retention, and Vault Pattern Description data sets. NOTE: READ and UPDATE access to the TMC and Audit data sets are controlled by the YSVCUNCD and YSVCCOND resource names, and by standard ACP data set controls, because some CA 1 utilities use conventional OPEN/CLOSE methods. The following commands are provided as a sample for implementing data set controls: TSS ADD(SYS3) DSN(SYS3) TSS PERMIT(<audtaudt>) DSN(SYS3.CA1.AUDIT) ACCESS(READ) TSS PERMIT(<operaudt>) DSN(SYS3.CA1.AUDIT) ACCESS(READ) TSS PERMIT(<pcspaudt>) DSN(SYS3.CA1.AUDIT) ACCESS(READ) TSS PERMIT(CA1 STCs) DSN(SYS3.CA1.AUDIT) ACCESS(UPDATE) TSS PERMIT(<syspaudt>) DSN(SYS3.CA1.AUDIT) ACCESS(ALL) ACTION(AUDIT) TSS PERMIT(<syspaudt>) DSN(SYS3.CA1.AUDIT) ACCESS(UPDATE) TSS PERMIT(<tapeaudt>) DSN(SYS3.CA1.AUDIT) ACCESS(ALL) ACTION(AUDIT) TSS PERMIT(<tapeaudt>) DSN(SYS3.CA1.AUDIT) ACCESS(UPDATE) TSS PERMIT(<tstcaudt>) DSN(SYS3.CA1.AUDIT) ACCESS(ALL) ACTION(AUDIT) TSS PERMIT(<tstcaudt>) DSN(SYS3.CA1.AUDIT) ACCESS(UPDATE) TSS PERMIT(<syspaudt>) DSN(SYS3.CA1.RDS) ACCESS(ALL) ACTION(AUDIT) TSS PERMIT(<syspaudt>) DSN(SYS3.CA1.RDS) ACCESS(UPDATE) TSS PERMIT(<tapeaudt>) DSN(SYS3.CA1.RDS) ACCESS(ALL) ACTION(AUDIT) TSS PERMIT(<tapeaudt>) DSN(SYS3.CA1.RDS) ACCESS(UPDATE) TSS PERMIT(<tstcaudt>) DSN(SYS3.CA1.RDS) ACCESS(ALL) ACTION(AUDIT) TSS PERMIT(<tstcaudt>) DSN(SYS3.CA1.RDS) ACCESS(UPDATE) TSS PERMIT(<audtaudt>) DSN(SYS3.CA1.TMC) ACCESS(READ) TSS PERMIT(<operaudt>) DSN(SYS3.CA1.TMC) ACCESS(READ) TSS PERMIT(<pcspaudt>) DSN(SYS3.CA1.TMC) ACCESS(READ) TSS PERMIT(CA1 STCs) DSN(SYS3.CA1.TMC) ACCESS(UPDATE) TSS PERMIT(<syspaudt>) DSN(SYS3.CA1.TMC) ACCESS(ALL) ACTION(AUDIT) TSS PERMIT(<syspaudt>) DSN(SYS3.CA1.TMC) ACCESS(UPDATE) TSS PERMIT(<tapeaudt>) DSN(SYS3.CA1.TMC) ACCESS(ALL) ACTION(AUDIT) TSS PERMIT(<tapeaudt>) DSN(SYS3.CA1.TMC) ACCESS(UPDATE) TSS PERMIT(<tstcaudt>) DSN(SYS3.CA1.TMC) ACCESS(ALL) ACTION(AUDIT) TSS PERMIT(<tstcaudt>) DSN(SYS3.CA1.TMC) ACCESS(UPDATE) TSS PERMIT(<syspaudt>) DSN(SYS3.CA1.VPD) ACCESS(ALL) ACTION(AUDIT) TSS PERMIT(<syspaudt>) DSN(SYS3.CA1.VPD) ACCESS(UPDATE) TSS PERMIT(<tapeaudt>) DSN(SYS3.CA1.VPD) ACCESS(ALL) ACTION(AUDIT) TSS PERMIT(<tapeaudt>) DSN(SYS3.CA1.VPD) ACCESS(UPDATE) TSS PERMIT(<tstcaudt>) DSN(SYS3.CA1.VPD) ACCESS(ALL) ACTION(AUDIT) TSS PERMIT(<tstcaudt>) DSN(SYS3.CA1.VPD) ACCESS(UPDATE)

CA 1 Tape Management 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. On-line applications offer the capabilities to directly access the CA 1 Tape Management Catalog (TMC) for query and update purposes. CA 1 special tape handling privileges offer the ability to process special tape requirements, such as BLP and foreign tapes.

Note 3 The data set OPEN/CLOSE security call will be handled by the CA 1 interface. To avoid duplication of security checking, the control option TAPE should be turned OFF in the TOP SECRET Control Options. Note 4 The UX0AUPD will specify YES only if you alter the fields in the TMC and the TMSUXxA (for r11.5 and below) or TMSXITA (for r12.0 and above) is changed.

The systems programmer/IAO will ensure that the CA 1 external security options are specified in accordance with the ACP being used. CA 1 Tape Management ACP security interfaces are controlled by options coded in the TMOOPTxx member identified in the TMOSYSxx member of the data set allocated by the TMSPARM DD statement in the TMSINIT STC. The specific required option settings are dependent on the ACP in use on the system.

CA 1 Tape Management default system password is common with all CA 1 systems. With this password, CA 1 tape processing can be deactivated. This could allow for unauthorized access to information stored on tape volumes and the CA 1 Tape Management Catalog (TMC). The result may threaten the integrity and availability of the CA 1 Tape Management System, and compromise the confidentiality of customer data.Information Assurance OfficerSystems Programmer
