In this MOOC, we will focus on learning how network systems are secured using firewalls and IDS. This will include understanding the basic components of network security, constructing a dual-firewall DMZ, and defining security policies to implement and enforce these rules. Building upon these lessons we will go in-depth on the popular Linux firewall. Finally we will learn about Network IDS and Host IDS, including a deep dive into Snort.
