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.
Secure Network Defense
In this module, we will learn how to construct an DMZ firewall system with dual firewalls to protect a site. We will also learn how to define critical security policies, their enforcement procedures, and apply related security design principles for the firewall system.
Implement Firewall with Linux IPTable
In this module, we will learn how to use Linux iptables to implement firewall rules for filtering packets, and SNAPT or DNAT address port translation, and the security policies.
Intrusion Detection Systems
In this module we will introduce the Snort IDS, discuss evaluation and performance of network firewalls, and finally cover Host IDS.
