SECURITY DEVICE BASED ON SITUATION INFORMATION AND METHOD THEREOF

摘要

A contextual information based security apparatus and a method thereof are provided to make the current context information based dynamic access control of a user possible by periodically grasping the contextual information. A security rule managing unit(210) produces a security rule required for the service access. A communication unit(250) receives an access request message to a specific service from a communication terminal. A contextual information managing unit(220) collects the contextual information for showing the situation of the communication terminal. An access controller(230) determines whether to allow the communication terminal to access the specific service through the security rule and contextual information.
