Static verification of security requirements in role based CSCW systems

Abstract

In this paper, we present static verification of security requirements for CSCW systems using finite-state techniques, i.e., model checking. The coordination and security constraints of CSCW systems are specified using a role based collaboration model. The verification ensures completeness and consistency of the specification given global requirements. We have developed several verification models to check security properties, such as task-flow constraints, information flow or confidentiality, and assignment of administrative privileges. The primary contribution of this paper is a methodology for verification of security requirements during designing collaboration systems.
