User Access Domain Management System-ADAMS

Internetworking is becoming the technology platform for a growing range of business uses. When you connect your local network to the Internet, the single most important measure you can take to prevent break-ins is to define a network security policy. In this work, we have examined- how one can provide a transparent network, while preserving security policy of organizations by implementing and maintaining strict access control using firewalls.

We propose a “User Access Domain (UAD)” to provide user-level grouping, and a “Access Domain Control Layer (ADCL)” to support the user level domain over the organizational networks with firewalls. While the User Access Domain provides the framework for virtual private networks the Access Domain Control Layer provides firewall-transparent TCP/UDP connectivity in what appears to be a seamless logical network spanning the User Access Domain. Moreover, the access-control policy can be formulated in more relevant terms like user identity, user role, source-destination, service etc. A proof-of-concept prototype is presently operational.
