Fix Recommendation

The IAO will ensure that update and allocate access to program product data sets is limited to system programmers only, unless a letter justifying access is filed with the IAO, and all update and allocate access is 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 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 commands are provided as a sample for implementing dataset controls:

SET RULE

$KEY(S2C)
$PREFIX(SYS2)
CSL.- UID(syspaudt) R(A) W(L) A(L) E(A) DATA(DEFAULT SYSPROG)

$KEY(S3C)
$PREFIX(SYS3)
CSL.- UID(syspaudt) R(A) W(L) A(L) E(A) DATA(DEFAULT SYSPROG)

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 datasets, other VSAM files and alias’s. As an authorized program, Catalog Solution bypasses many of the normal system security facilities — catalog and dataset passwords in particular. Improper use of Catalog Solution can result in non-synchronized catalog, dataset, or VVDS record groups. Therefore, certain commands should not be made available to the user community. As delivered, Catalog Solution bypasses dataset security checking for VSAM datasets 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 system programmers who perform in the specific role of Storage management.
