The encroachment of digital technology into our lifestyle and corporate environment has given rise to the need for individuals to safeguard personal information, and for organizations to protect trade-secret information either stored in computers or transmitted over LANs and WANs. A secure network and communication environment requires the services of encryption mechanisms, user password authentication, and network and user-interface based access control schemes that prevent unauthorised access to application programs and operating systems. While various encryption and authentication security mechanisms have garnered a lot of development effort, access control schemes using a virtual dedicated-media network system have not been fully developed. A dedicated-media network enables the authorization of access based on non-repudiate authenticity of the source. This capability presently cannot be implemented in shared-media networks. The paper introduces a a virtual access control configuration protocol (VACCP) which provides a dynamic security access authorization mechanism. The VACCP performs token-basad access security control to an application's user-interface resources. The VACCP security program is designed to control remote access for both the shared-media and dedicated-media mode of communication. The VACCP security measures are implemented as a network session-layer protocol which governs the access capability and assigns access authorization to each application program on a per-user-basis
