At the home or anywhere, you have set up a WiFi network or your broadband provider has given you a shared Internet connection with customers in the same building, this invites trouble of attacks. You are very vulnerable to ARP cache poisoning attack. ARP poisoning happens when a hacker fools you machine. ARP means Address Resolution Protocol. An ARP is used by the network to associate an IP address with a devices MAC address, in short ARP connects devices on a network.

The connection works without any authentication, so a device can easily pretend to be another. Hackers can sneak into your network and link any device using any IP and Mac address. This way the hacker can make the router think that his computer is yours and vice versa. By this what happens is, when you access your account, your device will send all the data packets to the hackers device.

NOW THE SOLUTION TO THIS :

· Assign static IP address to network devices and static ARP entries.

· For Windows, run ipconfig /all in command line, it will tell you your computers IP and Mac addresses of each device on your network.

· Run arp –s command to add static entries to those devices.

One can also use Anti-ARPSpoof . This software tool would set up a static route entry which would prevent such attacks. This is an opensource tool called as ArpON. It identifies and blocks all ARP poisoning and spoofing attacks.
