APPARATUS AND METHOD FOR DEFENDING A MODULATION OF THE CLIENT SCREEN

摘要

PURPOSE: An apparatus and method for defending a modulation of a client screen is provided to prevent the transformation of a client screen due to a web injection attack and a memory hacking attack by offering a dynamically created random web to the client. CONSTITUTION: A random web generator(230) changes the same web page into a random URI(Uniform Resource Identifier) by the requests of clients, creates different random web sources, and supplies the random web sources to the clients. A web modification determiner(250) determines the screen modification of the random web sources by comparing the generated web source ID value about the random web source and the generated web source ID value.
