The National Computer Systems Laboratory (NCSL) of the National Institute of Standards and Technology (NIST) and the National Computer Security Center (NCSC) of the Department of Defense (DoD) co-sponsored the Twelfth National Computer Security Conference held in Baltimore, Maryland on October 10-13, 1989. The theme of the conference, "Information Systems Security: Solutions for Today—Concepts for Tomorrow," highlighted the broader focus of information systems security which now challenges the user community, vendors, system developers, and administrators. Major areas addressed included advanced research developments and emerging technologies, network security architectures, risk management, management and administration issues in computer security, and an expanded focus on education and ethics. More than 2,000 attendees from government, industry, and academia participated in the 4-day conference, which was co-chaired by NCSL's Irene Gilbert and NCSC's George Mitchell.
