Firewall and Intrusion Detection Systems

This intermediate-level course, Firewall and Intrusion Detection Systems, introduces the fundamentals of firewalls and intrusion detection systems (IDS), two essential components of modern network security. Designed for learners who want to strengthen their understanding of network protection and threat detection, the course combines core concepts with practical implementation approaches.

What you will learn 

Participants explore how firewalls control and filter network traffic, prevent unauthorised access, and support secure network design. The course also examines the role of IDS and intrusion prevention systems (IPS) in detecting suspicious activity, monitoring threats, and supporting timely response. The module structure covers firewall and IDS fundamentals, firewall policies and intrusion detection, and intrusion prevention concepts including IPS signatures and monitoring. 

By the end of the course, learners will understand:

• The basic principles of firewalls and IDS

• How firewall rules and policies support network defence

• How IDS/IPS solutions contribute to detecting and preventing cyber threats. 

The course is fully online and self-paced, making it suitable for learners seeking practical introductory knowledge in network security.
