Arp Spoofing And Defense, In The Lan

With the progress of society, people's demand on the network is growing; Internet and network services, network applications and other components are requiring to have a secured network environment. Interconnection of networks generally use the TCP / IP protocol, which is an industry standard protocol family and protocol. There are many security vulnerabilities, causing the network vulnerable to hacker attacks.Address Resolution Protocol (Chinese name: Address Resolution Protocol), referred to as ARP, is a computer address translation of the agreement, turn the IP addresses into physical addresses. Similarly, there are security vulnerabilities, ARP deception is a computer virus spread via the Internet and LAN, it makes the computer network fail to function properly to achieve the goal of attacking.The purpose of this thesis is to reveal the ARP protocol flaws, and the use of ARP cheating attack on the local area network means and how to defend ARP cheating attack on the local area network, and build a practical model. I first analyzed the performance of the LAN ARP forms of deception, attack methods and means of defense that some of the current situation, and describes some of the knowledge of network security. Second, the details of the ARP cheating detailed analysis, including the deception theory, means of attack, ARP spoofing vulnerability and so on. Again, details on the ARP detection methods and means of defense. At last, at Zhejiang Yuexiu Foreign Language College, Institute of foreign economic management I prevented the deployment of ARP instance, using the means to improve network security, resist ARP cheating attack.
