Chapter 1: Understanding the Core Technologies
In this chapter, we're going to examine the core technologies that make up the Palo Alto Networks firewall.
We are going to take a closer look at how security zones control how security, Network Address Translation (NAT), and routing verdicts are made. We will review the mechanics behind App-ID and Content-ID so you get a deeper understanding of how packets are processed and security decisions are made by the firewall, and we will review how User-ID contributes to a more robust security stance by applying group-based or user-based access control.
This chapter will cover the following topics:
- Understanding the zone-based firewall
- Understanding App-ID and Content-ID
- The management and data plane
- Authenticating users with User-ID
