Forensic Certification: GNFA

Forensic Certification:

GIAC Network Forensic Analyst (GNFA)


Attacks on our systems are becoming increasingly broad and complex. It is simply not feasible to conduct full host-based forensic analysis on every system in an organization of any size. The proper use of network forensics can enable examiners to determine the origin and impact of malicious events quickly and effectively.

The GNFA certification is for professionals who want to demonstrate that they qualified to perform examinations employing network forensic artifact analysis. Candidates are required to demonstrate an understanding of the fundamentals of network forensics, normal and abnormal conditions for common network protocols, the process and tools used to examine device and system logs, wireless communication and encrypted protocols.

*No Specific training is required for any GIAC certification. There are many sources of information available regarding the certification objectives' knowledge areas. Practical experience is an option; there are also numerous books on the market covering Computer Information Security. Another option is any relevant courses from training providers, including SANS
