Study on Buffer Overflow Attack and New Protection Method

With the rapid development of Internet, network security is becoming more and more important. Among the increasingly mature technologies used by hackers, buffer overflow is one widely used by hackers to attack computer. If it can be eliminated efficiently, most security problem can be solved. This paper analyzes the principle of buffer overflow, primary intrusion process, intrusion mechanism and protection method in detail, and then produces a PAR-AD algorithm. This algorithm will help to find out buffer overflow intrusion automatically and strengthen the security of network.
