Black Hole Attack Prevention Using Computer Emulation Technique

Security attacks increased in network day by day. Black hole attack is a software tool to generate the webpage attack. Black hole attacks are simply referred to the drive by attack (Drive by attack occur when user visit the malicious webpage).There is various tool used in the black hole attack. Firesheep is one of the tool used to create the attack and it having high vulnerability chances then independent of all operating system. This paper proposed, the attacks are detected by using the blacksheep tool in which gives the alert message of somebody using the firesheep in this network. Finally prevent the webpage by using CPU emulator. In this emulator having the emulation algorithm used to prevent the webpage. The emulation algorithm works based on automata theory. It can get the source code and execute the decoding procedure by reading instruction by instruction.
