Tunneling and Firewalls

Architecture and Background

Aaron Grothe - Tunneling and Firewalls A Firewall is the first line of defense for almost every LAN connected to the Internet.

Vulnerability Analysis

Using a Firewall many System Administrators restrict privileges to services they do not want to allow access to such as telnet and ftp.

Exploitation and Demonstrations

Using tunneling software, people can re-enable those services by establishing virtual data paths through allowed protocols such as http.

Remediation and Defensive Strategies

The talk will provide an overview of how tunneling may be used, how to combat it, and when to use it. There will be a demonstration of how tunneling works using the httptunnel software. Aaron Grothe is a System Administrator for a small startup based in Omaha, Nebraska.
