Websites that give a good analysis and comparison of SPI and Application Layer Firewalls.
Posted on 2005-05-09
We currently have a SPI based firewall and I have just recently found out about application layer threats (HTTP tunneling) and firewalls. I need a good source of information that compares and contrasts both and discusses the threats of each type in order to make an evaluation and decision.
Your opinions and experience may be helpful but I can't give points for them, I need hard evidence and facts to back up my proposal to upper management. Many and varied sources will be helpful.
