METHOD AND APPARATUS FOR PROTECTING INTERNAL NETWORK USING TRAFFIC ANALYSIS AND DYNAMIC NETWORK ACCESS CONTROL PER FLOW

摘要

PURPOSE: A dynamic access control system per flow and a method thereof are provided to perform control about an original cyber attach through dynamic access control per flow and traffic usage shape analysis. CONSTITUTION: An access control server generates access permit state information of flow from a specific packet about the flow received from a user. An access control server examine whether an access through a flow is a normal access or not. The access control server is operated in access control mode to be blocked as a rule.
