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. The installing systems programmer will identify if any additional groups have UPDATE access for specific data sets, and once documented work with the ISSO to ensure they are properly restricted to the ACP (Access Control Program) active on the system.

The following commands are provided as a sample for implementing data set controls:

Catalog Solution allows you to monitor your catalog environment to help identify and correct structural catalog problems before they create system outages. Catalog Solution is a valuable tool in planning for or implementing System Managed Storage, as well as ensuring daily system availability. Catalog Solution is a comprehensive facility for the management, maintenance, repair, and recovery of the MVS catalog environment that complements the IDC Access Method Services (IDCAMS) utility.

Catalog Solution helps you in the five key areas: Maintenance, Diagnostics, Reporting, Backup and Recovery, and SMF management.

Catalog Solution is a very powerful tool that can pose risks if not properly controlled. If security is not properly implemented, the users of the product could present data integrity exposures, bypass security for catalog data sets, other VSAM files, and aliases. As an authorized program, Catalog Solution bypasses many of the normal system security facilities - catalog and data set passwords in particular. Improper use of Catalog Solution can result in non-synchronized catalog, data set, or VVDS record groups. Therefore, certain commands should not be made available to the user community. As delivered, Catalog Solution bypasses data set security checking for VSAM data sets and BCS processing. Clearly there are risks associated and valid requirements exist to ensure full external security controls are properly implemented for the Catalog Solution product.

Properly securing the use of various commands and features is crucial. All Catalog Solution functions should be reviewed for potential security exposures and to prevent unauthorized use. Some Catalog Solution functions allow for bypassing of security controls, and as such shall be restricted to systems programmers who perform in the specific role of Storage management.</fixtext><fix id="F-26124r1145208_fix" /><check system="C-26136r1144742_chk"><check-content-ref href="zOS_Catalog_Solutions_for_RACF_STIG.xml" name="M" /><check-content>Refer to the following report produced by the Data Set and Resource Data Collection:

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.)

Ensure that all Catalogued Solutions resources and/or generic equivalents are properly protected according to the requirements specified in Catalogued Solutions Resources table in the z/OS STIG Addendum.

Use Catalog Solutions Resources table in the z/OS STIG Addendum. This table lists the resources, access requirements, and logging requirements for Catalogued Solutions. Ensure the following guidelines are followed:

The RACF resource access authorizations restrict access to the appropriate personnel.

The RACF resource logging is correctly specified.

The RACF resource access authorizations specify UACC(NONE) and NOWARNING.
