Computer Supported Collaborative Work CSCW is a topic of considerable academic inquiry and rapid commercial development. Meeting Room Systems, Conferencing System, Co-authoring and Argumentation Systems, Message Systems and Autonomous Agents which support group collaboration currently exist however, Department of Defense DoD computer security requirements as they impact CSCW system design has received little attention. This thesis describes CSCW systems and relates group dynamic issues to predict the form of the sophisticated CSCW which will probably become commonplace in the future. Next the Trusted Computer security Evaluation criteria TCSEC with which all DoD systems must comply are synopsized. An extension of the Bell-LaPadula model underlying the TCSEC requirements is proposed which would allow Functionally Trusted CSCW FT-CSCW, CSCW which would meet many but not all of the TCSEC requirements. Possible first order efficiency effects of FT-CSCW, including the effect of sparse group domains, the breakdown of compartmentation, and organizational stratification are discussed. Second order social effects are also discussed, as are possible FT-CSCW problems unstable group membership, attempts to implement Quality Improvement Circles, inter-group CSCW and the effect of visitors. Finally, some suggestions are made for future FT-CSCW research.
