Access Control for Inter-Organizational Computer Network Environment

The Internet has evolved into an interconnection of networks on an organizational basis from the early stages where the interconnection was primarily on a network basis. The original protocol architecture, which essentially sought ubiquitous connectivity, has little scope for incorporating access control, a feature for which the demand increases with connectivity. In this work, we have taken up this issue. We have examined- how one can provide a transparent network, while preserving security of organizations by implementing and maintaining strict access control using firewalls.
