In today’s rapidly evolving digital landscape, cyber threats are becoming increasingly sophisticated and elusive. Attackers employ advanced techniques to infiltrate systems, often bypassing traditional security measures. For security professionals, this presents a significant challenge: how can we defend against threats that are designed to evade detection? The answer lies in integrating data science with modern security practices. This course is specifically designed for defenders who want to stay ahead of emerging threats by blending human intuition with machine-driven analytics. In the age of data overload, it’s not enough to simply rely on outdated detection approaches. Defenders need to harness the power of modern data science tools and techniques to uncover hidden anomalies, detect behavioral patterns, and identify subtle signals of compromise that may otherwise go unnoticed. This course equips you with the skills needed to navigate and combat the evolving cybersecurity landscape by utilizing cutting-edge techniques in data science. Throughout the course, you will dive deep into log analysis, threat detection hypotheses, and machine learning models applied to real-world cybersecurity scenarios. You will gain hands-on experience using industry-standard tools like Splunk and Jupyter Notebooks, allowing you to apply what you’ve learned to live data and active threats in your organization or in a training environment. This course is built for defenders who want to sharpen their hunting instincts and use data more effectively. It’s ideal for SOC analysts ready to move beyond alert triage, threat hunters who want to uncover deeper behavioral patterns, blue team engineers looking to build repeatable detection workflows, and cybersecurity students eager to gain hands-on experience with tools like Splunk and Jupyter. Learners should come in with a basic understanding of Python, familiarity with common log formats, and a solid grasp of core cybersecurity concepts. With these foundations in place, you’ll be able to move comfortably into the data-driven workflows and hands-on hunting techniques explored throughout the course. By the end, you’ll understand the full threat hunting lifecycle and how machine learning strengthens hypothesis-driven investigations. You’ll be able to clean, enrich, and visualize raw telemetry; apply anomaly detection techniques like Isolation Forest and DBSCAN; and design a complete ML-powered hunt in Splunk and Jupyter that detects suspicious behavior with clarity and confidence.

Syllabus

Course Introduction

In this course, you’ll learn how to combine threat hunting fundamentals with data science techniques to uncover hidden threats that traditional security tools often miss. You’ll work with real log data, build hunting hypotheses, and apply machine learning models to detect anomalies, behavioral patterns, and subtle signs of compromise across enterprise environments. Through guided instruction, hands-on labs, and practical examples using Splunk and Jupyter Notebooks, you’ll develop the skills to operationalize ML-powered threat hunts, strengthen detection workflows, and respond more effectively to advanced, evasive attackers.

Introduction to Industrial Threat Hunting

In this module, you’ll explore what threat hunting really means and why it has become essential for modern security teams. We’ll break down how hunters move beyond automated tools to search for hidden or unusual activity that may signal an active compromise. You’ll learn the core concepts, terminology, and frameworks that shape effective hunting, along with the mindset of assuming adversaries may already be inside your environment. By the end, you’ll understand why proactive hunting is critical for stopping attacks early, reducing impact, and strengthening your overall detection strategy.

Data Science for Cybersecurity

In this module, you’ll learn how data science strengthens modern threat hunting by helping you make sense of large, noisy security datasets. We’ll walk through the essentials of cleaning and shaping log data, visualizing behaviors, and building simple machine learning models to spot anomalies. You’ll get hands-on practice with Python tools like pandas, scikit-learn, and Jupyter Notebooks, and see how these techniques feed into SIEM platforms such as Splunk and Elastic. By the end, you’ll understand how data science supports faster detection, smarter investigations, and repeatable, automated hunting workflows.

ML Algorithms for Threat Detection

In this module, you’ll explore the unsupervised machine learning techniques that power modern anomaly detection in security environments. We’ll break down how models like Isolation Forest, DBSCAN, Z-Score Analysis, and One-Class SVM uncover unusual patterns without relying on labeled data. You’ll practice applying these algorithms to real-world scenarios such as suspicious logins, odd network traffic, and unusual system behavior. By the end, you’ll understand how these ML methods help you surface hidden threats that traditional rules often overlook.

Operationalizing in Splunk and Jupyter

In this module, you’ll learn how to turn machine learning models and analytical techniques into practical, repeatable threat-hunting workflows. We’ll walk through how to ingest and prepare data in Splunk, write SPL for clean feature inputs, and build detection notebooks that analyze and score events in Jupyter. You’ll also see how both platforms work together to run full end-to-end hunts, from data extraction to investigation. By the end, you’ll be able to operationalize ML-driven detections and apply them directly to real security telemetry.

Course Conclusion

In this wrap-up module, you’ll bring all your threat-hunting skills together by building a complete anomaly-based detection workflow using Splunk and Jupyter. This final project puts your log analysis, SPL queries, and ML techniques into practice, showing your ability to uncover hidden threats, visualize suspicious behavior, and map findings to ATT&CK. It’s your chance to demonstrate real-world readiness and apply everything you’ve learned across the course.
