Abstract
The Defense Information Systems Security Program (DISSP) was initiated at the
request of the Assistant Secretary of Defense (Command, Communications and Intelligence).
The Defense Information Systems Agency (DISA) and the National Security Agency (NSA) agree
to cooperate in achieving eight security objectives. These objectives were in the areas of:
Security policy
Architecture
Standards and Protocols
Accreditation Procedures
Technology
Transition Planning
Organizational Improvement
Products and Services Availability
Accordingly, a DISSP Office was established and among its responsibilities was the development
of the Department of Defense (DoD) Goal Security Architecture (DGSA). The DISSP has since
become a part of the Center for Information System Security (CISS) in DISA. The CISS assists
DoD organizations in the transition of exsisting systems, and in the development of new systems
in accordance with the DGSA.
Concurrent with the develpment of the DGSA, efforts were underway within the DISA to define
information system archtectures for the Defense Information System (DIS). These efforts focused
under the Technical Architecture Framework for Information Management (TAFIM). The TAFIM is
intended to be generic and sufficiently flexible in its definition so that specific systems
may be developed or modified to satisfy mission goals. The TAFIM is thereby a "goal information
system architecture" and has, as Volume 6, incorporated teh DGSA as its "goal security archtecture".
