Punching holes into firewallsAdded by Papergrl
Description:
In a TCP/IP environment, the typical corporate firewall configuration is to block everything (both incoming and outgoing), and give access to the internet only through a HTTP proxy. The proxy usually has filtering capabilities (censors URLs and file types), and access to the proxy often requires credentials (login/password). This gives greater contol to the network administrator over what and who is going in and out of the network. This paper demonstrates how to encapsulate any TCP-based protocol (SMTP, POP3, NNTP, telnet...) into HTTP, thus bypassing the firewall protection/censorship (depending on your point of view)
