I'll tell you how hard and how long. A firewall is a bunch of asics, a CPU, memory and storage. Its basically an application specific computer. Thus, find a vulnerability within the system that has not been patched yet and exploit it. Though the much easier and more frequently used attack against a firwall is an event driven DDoS attack such as a spoofed DNS attack. Frequently, if the firewall is configured to perform certain Layer 4-7 inspections such as HTTP, DNS, SMTP, and it does or even does not use ASICs to route those lookups, you can overwhelm it and the CPU with bogus lookups at a really high rate. This will destroy the traffic passing through it. ------------------------------------------------------------------------ Securing Apache Web Server with thawte Digital Certificate In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.
