Aiming at the hardware system, network protocol and database and so on, whether the design of its defects, or numbers of Network security vulnerability caused by human factor, they may be some other graph used by the hacker and launched a series of attacks. So establishing an effective network security system is imminent. In this paper, an analysis of network attack steps, ways and normal attack tools and so on, and focusing on these aspects to introduce some methods of the network attack and defense, to let the readers understand the process of hacker attack, to adequate preparation to do a good job in dealing with network threats to ensure safe and reliable network operation.
