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.
Overview
Syllabus
- 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.
