Applications and attacks have quickly learned that they can evade firewalls and other security devices via HTTP tunneling. HTTP tunneling is a method of evading network firewalls and access control policies by encapsulating traffic in HTTP headers and sending it over the most open port in the network &ndash; port 80.
