The Application System/400 (AS/400) is IBM's family of full-range, general purpose computers, which encompass a broad range of related models. This book is a complete guide to the AS/400 system, utilities, database structure, and programming.

Networking/AS/400 Timely, effective security for the AS/400(r) It may be hard to believe, but the AS/400 is not tamperproof, despite IBM's design efforts to that end. Consequently, the growing popularity of this system as a server means a greater security risk for everyone who uses it. AS/400 Security in a Client/Server Environment shows how to mount the strongest possible defense against security breaks in the AS/400, and how to recover quickly when they do occur. This readable, user-friendly book cuts through many commonly held misconceptions about security in general, and the AS/400 in particular. Through examples and case studies that read like detective stories, this book explains why the AS/400 represents such a tempting target to hackers, how bugs and viruses can be inserted into the system, and what preventive methods and techniques can fight them. This book provides the tools for bolstering the security of the AS/400 without restricting the normal functioning of the organization that is using it, including: Pointers on how to plan ahead for security problems when using the AS/400 as a server A 31 2" diskette containing security auditing and antivirus programs that clean up AS/400 bugs and viruses Figures and tables that illustrate the connection between design and potential threat Easily adaptable auditing procedures and technical recommendations Details of security weaknesses in the AS/400 system A complete overview of AS/400 security, from resource authorization models to today's client/server environments AS/400 Security in a Client/Server Environment provides a complete guide for IT managers; systems developers, designers, analysts, and programmers; and database developers and administrators, as well as anyone interested in the wider context of the AS/400's evolution.
