This paper presents a brief historical overview of data security research at RAND. It describes two currently active projects (1) an NSF grant using systems studies and mathematical studies to establish a theoretical foundation for data security and a set of relationships that could form the basis of a data security engineering discipline; and (2) a Computer Security Assurance project that continues previous RAND studies to test system security through penetration, and will be developing security assurance techniques. The paper also outlines plans for future work and presents the authors' views on the problems of secure data sharing. One important conclusion--the data security research programs aimed at long-term solutions must also focus on the computer systems expected to be in use when the results become available, not on the system concepts in use today, which are already on the way out.
This report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
