ARP spoofing


It is possible to supersede other MAC addresses in the network because the associated switch lacks protection mechanisms, such as PortSecurity.


  • Steal sensitive information.
  • Facilitate other attacks such as Denial-of-Service DoS attacks, session hijacking and man-in-the-middle MitM attacks.


Set network controls (PortSecurity) in the affected switches.

Compliant code

All switches should have the port security enabled

server {
index: "index.html";
listen: "localhost:4446 ssl";
server_name: "localhost";
port {
port-number: "4446";

Non compliant code

There is a switch with port-security disabled

server {
index: "index.html";
listen: "localhost:4446 ssl";
server_name: "localhost";
port {
port-number: "4446";
port-security: disabled;
