In the field of network security, with the continuous "fool" of hacker application technology, IDs of intrusion detection system is gradually increasing. In a network, only effective implementation of IDs, can be acutely aware of the attacker's violations, in order to prevent them!

Note the data to be tested, that is, January 1, November 25. Our system was cracked in November 26, from the same system. Intruders only take a short time to break the system. I guess it is an automated tool used by intruders to scan for known DNS vulnerabilities in many systems. The scan leaves. When the intruders review the results, they determine the system (including US) with the vulnerability and then start playing the game. Now we have pieced together the first part of our story. Intruder
