Use static ARP -the ARP protocol lets you define a static ARP entry for an IP address, and prevent devices from listening on ARP responses for that address.This makes all communication encrypted, and worthless for an ARP spoofing attacker. Use a Virtual Private Network (VPN) -a VPN allows devices to connect to the Internet through an encrypted tunnel.Here are a few best practices that can help you prevent ARP Spoofing on your network: To discover ARP spoofing in a large network and get more information about the type of communication the attacker is carrying out, you can use the open source Wireshark protocol. Because the IP address 192.168.5.1 can be recognized as the router, the attacker’s IP is probably 192.168.5.202. If the table contains two different IP addresses that have the same MAC address, this indicates an ARP attack is taking place. The output will look something like this: Internet Address Physical Address Use the following command to display the ARP table, on both Windows and Linux: arp -a Start an operating system shell as an administrator. Here is a simple way to detect that a specific device’s ARP cache has been poisoned, using the command line. How to Detect an ARP Cache Poisoning Attack If they do this for a large number of IPs, the target server will be bombarded with traffic. Distributed Denial of Service (DDoS) -the attackers can provide the MAC address of a server they wish to attack with DDoS, instead of their own machine.Alter communication -for example pushing a malicious file or website to the workstation.Perform session hijacking -if the attacker obtains a session ID, they can gain access to accounts the user is currently logged into.Continue routing the communications as-is -the attacker can sniff the packets and steal data, except if it is transferred over an encrypted channel like HTTPS.Once the attacker succeeds in an ARP spoofing attack, they can: ![]() The ARP spoofing attacker pretends to be both sides of a network communication channel
