#56 - Say Firewall One More Time

Have you ever heard someone say our firewalls block this type of attack?  In this episode, you can increase your understanding of firewalls so it won’t just be another buzzword. 

6 Basic categories of firewalls that we discuss on the show include:  

  1. Packet Filters focus on IP and port blocking 
  2. Stateful Inspection Firewall looks at active connections and consider context
  3. Network Address Translation Firewalls tools that allow private networks to connect to public ones and create secure enclaves
  4. Proxy Servers classify web traffic into topics that might be allowed or not allowed
  5. Web Application Firewalls block Web Application Attacks (SQL Injection,Cross Site Scripting, …)
  6. Next Generation Firewalls that try to do everything.
