Live Forensics: Data Collection from Compromised Systems

When a computer system is potentially compromised, acting quickly and correctly is critical. Simply shutting down a machine can destroy volatile evidence stored in RAM, wiping away the keys to understanding the intrusion. This text-only course provides a clear, step-by-step guide to performing live data collections safely and effectively. Through this course, you will transition from understanding basic security concepts to confidently gathering active system evidence. You will learn how to prioritize volatile data, execute collection commands, and preserve the integrity of your findings for further analysis. What you'll learn: - Understand the core principles of digital forensics, the order of volatility, and the chain of custody. - Capture volatile memory and running system states using standard command-line tools. - Retrieve critical live artifacts, including active network connections, logged-in users, and running processes. - Apply cryptographic hashing to verify and secure the integrity of collected evidence. - Document your collection methodology to maintain a reliable and defensible audit trail. - Explore modern collection techniques across both Windows and Linux operating systems. We begin with essential terminology and the foundational rules of evidence preservation. From there, you will study detailed, written walk-throughs of command-line tools and collection strategies that you can apply directly to real-world scenarios. This course is designed for cybersecurity beginners, system administrators, and aspiring incident responders. No previous digital forensics experience is required.
