Research and Implementation of ARP Attack Defense Software Based on SharpPcap

With the rapid application of IPV6 technology, network protocols become more and more secure, but it is easy to ignore the network security of IPV4 protocol in LAN. Especially in the network environment of the company and the campus network, ARP attacks caused by the loopholes in the ARP protocol are still rampant. In order to solve the defense needs of PC in LAN, an ARP defense software is designed and developed by SharpPcap framework. Without affecting the communication quality of the existing network, the current network state is obtained by monitoring and capturing the data packets of the backbone link to facilitate users to monitor the current network state and defend ARP attacks.
