Hello! I am a methodologist and instructor at Asibiont, and today I want to tell you about a course we created with special love and a practical mindset — "Digital Forensics and Incident Response (DFIR)".
Why is this topic so important right now? Cyberattacks are no longer rare events. According to the IBM Cost of a Data Breach 2025 report, the average cost of a data breach exceeded $4.9 million. Moreover, the average time to detect an incident is 277 days. Companies are critically short of specialists who can quickly collect digital evidence, reconstruct the chain of events, and prevent repeat attacks. DFIR is one of the most sought‑after and highest‑paid specializations in cybersecurity.
But how do you enter this field from scratch? Textbooks are overloaded with theory, video tutorials often become outdated, and practical tasks require access to real memory dumps and disk images. I myself started by reading Volatility documentation and the SANS brochure — it was difficult, time‑consuming, and at times boring. That is why at Asibiont we built the training differently.
What is DFIR and what will you learn in the course?
DFIR (Digital Forensics and Incident Response) is not just a set of tools, but a whole investigative methodology. You will learn to answer three main questions: "What happened?", "How did the attacker get into the system?", and "How can we prevent this from happening again?"
The course covers all key stages of a real investigation:
1. Host Forensics
You will master evidence collection from Windows, Linux, and macOS operating systems. The main tools are FTK Imager for creating disk images, KAPE (Kroll Artifact Parser and Extractor) for quickly extracting artifacts (Prefetch, Registry, Event Logs, Jump Lists). Using a real dump, you will learn how to find traces of malicious software execution and attacker movement within the system.
2. Memory Forensics
RAM stores encryption keys, running processes, network connections. You will work with Volatility and Rekall — learn to extract process lists, DLL dumps, analyze hooks, and detect injections. For example, in one lesson we analyze a case where memory concealed a rootkit that was not visible in Task Manager.
3. Network Forensics
Traffic is the "digital blood" of the network. You will learn to read PCAP files using Zeek (formerly Bro) and Suricata. You will understand how to detect DNS tunneling, port scanning, and data exfiltration. In the lab, we investigate a traffic dump from a real attack using Cobalt Strike.
4. Timeline Analysis and Malware Triage
Plaso (Plaso Langar Að Safna Öllu) and Timesketch will help you build a complete chronological timeline of events. You will see how to "extract" from hundreds of thousands of records the events that led to compromise. The Malware Triage section will teach you to quickly classify malicious files: static analysis (PE headers, strings) and dynamic analysis in a sandbox.
5. Evidence Collection, Threat Hunting, and Incident Response
Evidence collection is not just "copy files." We will cover Velociraptor for remote evidence collection, learn to map an attack using MITRE ATT&CK, and write incident response playbooks compliant with NIST SP 800-61.
Upon completing the course, you will be able to:
- Conduct a primary incident investigation on your own.
- Collect and document digital evidence so that it is admissible in court or during an audit.
- Use Threat Hunting to find threats before they cause damage.
- Develop response playbooks for your SOC team.
Who is this course for?
The course is designed for beginner cybersecurity specialists who are already familiar with the basics of networks and operating systems (preferred but not required). If you are an administrator looking to transition into security, or a student dreaming of joining a SOC, this is your starting point. We begin with the fundamentals: what a disk image is, how Volatility 3 works, why Plaso is needed. But by the middle of the course, you will be analyzing real‑world cases from practice.
How training works at Asibiont: AI that adapts to you
Our platform is not typical videos and PDF files. Each lesson is generated by a neural network individually for you. When you start the course, the AI assesses your level (not an entrance test, but an analysis of answers to initial questions) and your goals. If you are already comfortable with Linux but do not know Volatility, the program will not waste time reviewing OS basics and will immediately move on to memory forensics.
Why is this effective?
- Personalization to your pace. As an instructor, I know everyone has their own "bottleneck": some find it hard to remember Windows registry artifacts, others confuse memory dump types. The AI selects explanations specifically for your difficulties, rephrases the topic, and provides additional examples.
- Text‑based format with clear explanations. No boring lectures. Each lesson is a lively text with code, commands, and links to documentation. You can "speak out loud" the commands and immediately try them in the lab environment.
- 24/7 access and instant feedback. Confused about Volatility arguments? Type your question in the feedback field — and the AI generates an explanation with an alternative example. No waiting for a response from an instructor.
- Interactive labs with real dumps. We have prepared dumps from real incidents (anonymized, of course). You don't just read theory — you work with FTK Imager, KAPE, Zeek, Volatility in a virtual environment directly in your browser.
Modern learning is adaptability. When the world of cyber threats changes every day, there is no time to study what you already know or what is irrelevant to your task. AI‑generated lessons on Asibiont give you exactly the knowledge and skills you need, right now.
Conclusion
Digital forensics is a fascinating detective story in the world of bits. With each investigation you will feel your confidence and expertise grow. Our course "Digital Forensics and Incident Response (DFIR)" provides not just theory, but working tools and a methodology you can apply tomorrow.
