What is the GIAC GNFA certification exam?
The GIAC Network Forensic Analyst (GNFA) certification is one of the leading forensic analyst certifications, validating a practitioner's capability of performing examinations that involve network forensic artifacts. By earning the GNFA certification, you will demonstrate your understanding of the fundamentals of network forensics, normal and abnormal conditions for common network protocols, processes and tools for examining device and system logs, and wireless communication and encryption protocols.
The GIAC GNFA certification exam covers network architecture, network protocols, and network protocol reverse engineering, encryption and encoding, NetFlow analysis and attack visualization, security event & incident logging, network analysis tools and usage, wireless network analysis, & open source network security proxies.
The GIAC GNFA exam consists of 50-66 multiple-choice questions and must be completed within 2-3 hours. To pass the GNFA exam, a passing score of 70% is required. The GNFA certification is ideal for anyone with a solid background in computer forensics, information systems, and information security interested in computer network intrusions and investigations.
Here are the topics covered in the GNFA exam:
- Network architecture, network protocols, and network protocol reverse engineering
- Encryption and encoding, NetFlow analysis and attack visualization, security event & incident logging
- Network analysis tools and usage, wireless network analysis, & open-source network security proxies

What is network forensics?
You may have heard of forensics or forensic science once in your life. Forensic science is all about using scientific methods to assist the criminal justice system. It covers a wide range of topics, from analyzing DNA to studying pathology reports, toxicology, ballistics identification, and much more.
Forensics is no longer limited to traditional techniques like DNA analysis or identification of ballistics. The world of forensic science has expanded to include digital forensics, which involves digging up electronic evidence related to criminal investigations. According to IGI Global, network forensics deals with "monitoring and analyzing computer network traffic," making it a crucial component in the fight against cybercrime.
Processes Involved in network forensics
When it comes to network forensics, investigators must follow several crucial processes to ensure the integrity of their findings.
Here are some of the key steps:
- Identification: investigators identify and evaluate the incident based on the network pointers.
- Safeguarding: the investigators preserve and secure the data so that tampering can be prevented.
- Accumulation: a detailed crime scene report is documented, and all the collected digital shreds of evidence are duplicated.
- Observation: all the visible data is tracked along with the metadata.
- Investigation: a final conclusion is drawn from the collected shreds of evidence.
- Documentation: all the shreds of evidence, reports, and conclusions are documented and presented in court.
