About this Course

The Certified Network Forensics Examiner was originally developed for a U.S. classified government agency. The C)NFE takes a digital and network forensic skill set to the next level by navigating through over twenty modules of network forensic topics.

The CNFE provides practical experience through our lab exercises that simulate real-world scenarios which cover investigation and recovery of data in network, Physical Interception, Traffic Acquisition, Analysis, Wireless Attacks and SNORT. The course focuses on the centralizing and investigating of logging systems as well as network devices.
