Once a security management system is installed, a security domain is set. The domain remains unchanged if there is no system security officer's intervention. Therefore, it is impossible to respond to an attack which is done out of the security domain. This paper proposes a Shadowing Mechanism, a new approach in extending a security domain. It also presents an Intruder Tracing System, which is implemented based on the proposed technique. The Shadowing Mechanism keeps track of the intruder's new connections and shadows him/her by automatically establishing a security scheme for valnerable hosts following the intruder's movement path. It extends a security domain dynamically and minimizes spatial limitations on a traceable domain.
