CHAPTER 14 Configuring Basic Firewall Policies on Cisco ASA Cisco over the years has had a dedicated firewall appliance. Many years ago, it was a device named the PIX. As technology improved, a new device was created that leveraged all the features of the PIX and added some new ones. This new device is the Adaptive Security Appliance (ASA) . It is pronounced as if you are saying the three individual let- ters of A , S , A . it is important to understand the basics of a device before you configure it, so that's what we do here in this chapter. You first learn the logic of what the ASA goes through as it makes its determination about forwarding or filtering, and then once you understand that, we configure and implement a security policy and verify the secu- rity policy with the built-in tool called Packet Tracer.
