What you'll learn

Cyber attacks evolve constantly, and detecting them requires the use of different techniques, some of which are more useful for specific scenarios than others. In this course, Security Event Triage: Detecting Malicious Traffic With Signature and Session Analysis, you will gain the ability to detect those attacks by leveraging signature and session analysis. First, you will learn how to detect attacks with common, detectable characteristics using signature analysis with tools like Snort. Next, you will discover how session analysis, with tools like Zeek and Kibana, can allow you to detect attacks by spotting suspicious behavior, in a way that is much harder to evade than simple signatures. Finally, you will explore how to detect suspicious patterns even in encrypted traffic, without the need to decrypt it. When you are finished with this course, you will have the skills and knowledge of signature and session analysis needed to detect attacks using network data.

This course is part of our Security Event Triage series which leverages MITRE ATT&CK to identify advance persistent threat tactics at all levels of the cyber kill chain.
