Introduction to Intrusion Detection Systems (IDS)

About this course

This course introduces you to Intrusion Detection Systems (IDS), offering essential knowledge and hands-on skills for detecting and mitigating security threats. As cyberattacks become more sophisticated, learning to protect systems through IDS is a critical skill for IT and security professionals. This course is designed to give you a comprehensive understanding of both Host-Based (HIDS) and Network-Based Intrusion Detection Systems (NIDS). You’ll dive into core components, explore the differences between signature-based and anomaly-based detection, and gain practical experience by operating IDS tools on virtual machines. What makes this course unique is its combination of theory and real-world application: you’ll learn to configure IDS technologies, develop custom rules, and evaluate IDS performance quantitatively. By the end of this course, you’ll be equipped to identify and respond to security threats in various environments, from individual hosts to complex networks. This practical knowledge will set you apart, enhancing your ability to protect critical systems against emerging cyber threats.

What you will learn

• Understand the roles of HIDS and NIDS, their key components, and applications across cybersecurity contexts.
• Install and configure IDS solutions on VMs to detect real-time threats in host and network environments.
• Compare signature-based and anomaly-based detection methods and configure IDS rules accordingly.
• Use quantitative techniques to assess IDS effectiveness, analyzing data to select optimal solutions for security needs.
