This book offers critical and practical insight into one of the most important yet overlooked areas of systems management. Many corporations are in the process of changing their closed and proprietary information processing infrastructures to open, standards-based, integrated environments. The ability to maintain and extend security during this transition is of paramount importance to such organizations. Network Security is a practical guide to designing and implementing a variety of fundamental security mechanisms. The text defines specific cost-effective strategies and provides step-by-step implementation methodology. This book also provides in-depth coverage of controlling viruses and trojan horses, and presents advanced network security strategies for PC's, networked workstations, and high-performance systems. Fortified with this essential information, users can enjoy all the benefits of a network while securing confidential data.
