Due to the Stateless Property of the ARP protocol (It means that a response can be processed despite the request was never received), which introduces some security flaws that makes it vulnerable to various types of attacks resulting in leaks and/or damage of information, They have presented various feasible solutions, amongst these we find S-ARP (secure ARP) and ES-ARP (Secure and efficient ARP), these two, seek to resolve the failure of ARP security, changing and improving its original protocols and performing other configurations that are believed feasible to improve their security. In this article, we will execute an ARP poisoning in order to show the insecurity that the Protocol has, and to compare it against other alternatives, to show the safety of each of these.
