The National Computer Security Center (NCSC) and the Computer Systems Laboratory (CSL) are pleased to welcome you to the Eighteenth National Information Systems Security Conference. The new conference name reminds us that information systems, not just computers, must be secure. This year's program, with its theme "Making Security Real," is designed to help you plan for effective use of information security technology and to create security solutions. We believe the conference will stimulate a copious information exchange and promote a solid understanding of today's information security issues and protection strategies. The conference program addresses a wide range of interests from technical research and development projects to user oriented management and administration topics. This year, the program focuses on developing and implementing secure networks, technologies, applications, and policies. Papers and panel sessions address a broad spectrum of network security subjects including: security architecture, internet security, firewalls, multilevel security (MLS) products, and security management. Because the National Information Infrastructure (NII), and its present backbone--the Internet--are topics of increasing interest, the challenges they present are the subject of many presentations. As in the past, a number of tutorials introduce attendees to a variety of information security topics and project areas. As a new feature this year, we have invited the vendor award recipients to provide product information displays as part of the award ceremony.

Volume 1 contains the table of contents of presentations and panel summaries (pp. v-xiv) and author index (pp. xv-xvi).
