Network forensics training course description

This course studies network forensics—monitoring and analysis of network traffic for information gathering, intrusion detection and legal evidence. We focus on the technical aspects of network forensics rather than other skills such as incident response procedures etc.. Hands on sessions follow all the major sections.

What will you learn

• Recognise network forensic data sources.
• Perform network forensics using:
  Wireshark
  NetFlow
  Log analysis
  
• Describe issues such as encryption.
