introduction of hacking 2

Why need to study this paper?

This paper contains information that can be applied practically to secure or test the security of any kind of machines & therefore any information (although nothing is secure in this world at full extent) and to carry out the state of the art hacks.
So administrators and developers must study this paper carefully. Because, if you don’t know the attacking tactics, then how will you secure the systems from the attacks? Only knowledge is not enough, you must know how the things work practically, the dedicated attacker can invent new attacking technologies, therefore, you must be creative in finding out all of such techniques, which can be used to attack and only then, you can develop a security system effectively.
Remember, a single failure of security means total failure of security system. Because that single event can be proven deadliest. As in the words of NSA (National Security Agency-USA), “even the most secure safe of the world is not secure and totally useless if someone forgets to close its doors properly”.
