  • 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.

  • A Technical History of National CSS
    A Technical History of National CSS By Harold Feinleib Written: March 4, 2005 CHM Reference number: R0363.2016 A Technical History of National CSS By Harold Feinleib I knew I wanted to go into computers when I got my first program to work. That was quite a thrill. It happened in 1964 during my senior year at Cornell when I took the only course given in computers. I had to look to the Electrical Engineering school where we worked on a Burroughs 220, a computer filled with thousands of vacuum tubes that took up a good sized room. It was actually a very nice computer because it worked in decimal instead of binary. That memorable program was of course a Sort program—I had to sort a list of numbers. I wonder how many sort programs have been written before or since. It must be millions. With great enthusiasm, I interviewed at the campus-recruiting program where companies sent people to find new employees for their organization. In the 1960’s, unlike today, the job market was very active and no one had a problem getting started right after they graduated from college. I got some interest from three companies: Equitable Life to work in their actuarial program in New York City; IBM as a programmer to work in upstate NY; and with the Service Bureau Corporation to also work in midtown Manhattan. New York City was very appealing to me; I was 20 years old, and living in Manhattan was a very exciting prospect, so I took great interest in the Equitable and the SBC interviews.

    MANEWS Issue Number 21 the Mainframe Audit News This newsletter tells you stuff you need to know to audit IBM mainframe computers runinng with z/OS and the MVS operating system. This issue we show you how to plan the data gathering for your audit. Table of Contents 1. Planning Data Gathering for a Mainframe Security Audit 2. What Data to Gather for a RACF Audit 3 What Data to Gather for a CA-ACF2 Audit 4. What Data to Gather for a CA-TopSecret Audit 5. What Data to Gather for an MVS Security Audit 6. Other Considerations 7. Seminar Information and Miscellanea 1) Planning Data Gathering for a Mainframe Security Audit Getting the data you need at the beginning of an audit may be one of the most important things you can do to make the audit successful. Knowing what to ask for before the audit starts is key to getting it before you need it. You’ll learn below how to plan what data to ask for. In future issues we will show you how to interpret some of it, and how to make use of it in your audit program. This issue addresses only planning for your data gathering. To decide what to ask for, consider that mainframe (z/OS and MVS) security consists of two major parts: the security software and the MVS operating system security. You will likely want to limit your scope to one or the other. The security software is always one of these Big Three: · RACF (IBM’s Resource Access Control Facility) · CA-ACF2 (CA Technology’s ACF2) or · CA-TopSecret (CA Technology’s TopSecret, often called just TSS) Page 1 www.stuhenderson.com September, 2013 MANEWS Issue Number 21 the Mainframe Audit News The security software handles identification and validation of users (often by means of a userid and password).
