CICS Essentials Auditing CICS – a Beginner’S Guide
CICS Essentials Auditing CICS – A Beginner’s Guide Julie-Ann Williams Mike Cairns Martin Underwood Craig Warren ii CICS ESSENTIALS Foreword by Brian Cummings A thorough Audit Guide for CICS is something that is long overdue. This document provides a wealth of information about CICS, its operations, and its various resources and capabilities along with audit guidelines and recommendations. Various documents on AuditNet and other sources have taken a stab at parts or all of CICS, but are likely not up to date or sufficiently complete. CICS largely remains an environment that holds its mysteries against auditors and security officers alike. The results of poor understanding can lead to dangerous levels of unidentified risk to the applications and sensitive information of entities that use the power of CICS for critical business applications. Unlike any other environment, CICS security implementations fail in the first place because all of the security control is often only focused on transactions. Transactions are many levels of resources removed from the data files and data bases they query or update. In the end, we see the greatest level of security established for the least sophisticated technical users – end business users, and the least security facing the most technically sophisticated – the CICS sub-system programmer and the CICS Application programmer. For example, it is typical to leave FCT resources unsecured and to allow the CICS regions to have total rights to the data sets they access. This condition gives sub-system and application programmers full-reign to use CICS utilities to inherit the CICS regions’ authorities and gain full access to freely browse and update data. -
