Wireshark is the most widely used open-source network protocol analyzer. It captures live network traffic and provides deep inspection of hundreds of protocols. Analysts use display filters, follow TCP streams, extract objects from captures, and decode encrypted traffic (with keys) to investigate network activity.
Wireshark proficiency is expected in most technical cybersecurity roles. SOC analysts use it to validate alerts by examining actual packet data. Incident responders reconstruct attack sequences from Wireshark captures. Penetration testers analyze traffic to find credentials and understand application behavior. Multiple certifications test Wireshark skills.
