A Security Model for the Workspace Groupware Architecture
By: Lt(N) L.J. Terpstra
Supervisor: Maj W. Greg Phillips
Abstract
Research conducted during this thesis has resulted in the design, development and validation of an embedded security model for the workspace model, which allows groupware and collaborative security to be specified in terms of the conceptual level items of the systems with which they are implemented.
Computer Supported Cooperative Work encompasses activities relating to the study, research, design, development, implementation and use of computer-based technologies to support cooperative work. Groupware is the computer systems and software applications of computer supported cooperative work. Groupware supports groups of people engaged in a common task or goal, supports their interaction and activities as a group, and provides them with an interface to a shared environment. The Workspace Model is an architectural style being developed to support the description and implementation of a vast range of collaborative scenarios and groupware systems using the concepts of workspaces, components and connectors.
Security in computer systems and software applications is important as it prevents information from being obtained in an unauthorized manner and provides information integrity and availability assurances. The security of groupware systems is complicated by their collaborative and often distributed nature. If the workspace model is to be a useful tool for modeling, designing and developing groupware systems, it must provide for the implementation of adequate collaborative security.
This thesis outlines the design, development and validation of a security model for the workspace model.
