Chapter 10. Firewall Placement and Detection Techniques
In the previous chapter, we learned all aboutSSL. We also explored how SSL provides the authentication, confidentiality, and integrity to achieve transport layer security.
This chapter provides a brief overview of firewall technology, looking at its placement in a network and the services it offers. In this chapter, you will explore a different generation of firewalls and use cases. You will also learn where a firewall fits into a network and what it can and cannot do. Furthermore, the chapter covers the basics of TCP/IP, Traceroute, scanner tools, setting up firewalls, testing, the best practices to maintain firewalls, and much more. We will be covering the following topics:
- Firewall and design considerations
