Assume I,m in a LAN, that uses a Router. If someone redirects my all data packets to his computer then there is no privacy. This is happening in real. when I run "arp -a" command, I can see his IP address and I couldn't remove it using command "arp -d ". Does anyone know a way to avoid this arp access? or any other suggestions? Thank you.
Actually it is "ARP protocol Vulnerability" which is in the OSI model. As far as I know , this is under research & currently UNRESOLVED. iN lINUX U CAN AVOID THIS BY USING IPTABLES.
