Knowing how to detect and deter network reconnaissance (the first step in a wide range of cyberattacks) is a crucial part of an efficient defense, responding to today’s threat landscape.

In this hands-on workshop, you'll learn how adversaries map targets for mass exploitation, the foundations of network fingerprinting, and modern methods like JA4, JA4+, and MuonFP - including what these techniques can and cannot do. We'll dive into building eBPF filters to drop or flag unwanted connections, and explore how to mask your edge infrastructure from automated scans. We'll also discuss how to integrate fingerprinting into your workflows so you can stay one step ahead of both opportunistic and targeted attacks.

Whether you're an intermediate analyst seeking to understand the fingerprinting landscape or an advanced defender ready to build sophisticated filters, this workshop will give you the tools and insights you need.
