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.

Syllabus

Course Introduction

This course provides a comprehensive overview of Intrusion Detection Systems (IDS), focusing on both Host-based (HIDS) and Network-based (NIDS) technologies. Participants will learn to describe IDS components, analyze attack dynamics, and develop use cases for detecting insider threats and DDoS attacks. The course includes practical sessions on installing and operating HIDS and NIDS on virtual machines, as well as configuring tools like Suricata. Additionally, students will evaluate detection methods and conduct quantitative assessments to enhance their understanding of cybersecurity effectiveness.
