A protocol analyzer, also known as a packet sniffer, captures and inspects network traffic flowing across a network segment. If traffic is unencrypted, protocol analyzers can intercept sensitive information such as usernames, passwords, session tokens, and application data.
Log servers store logs, network scanners identify hosts and services, and firewalls filter traffic based on rules. Only protocol analyzers are designed to capture and inspect packet contents.
This capability makes protocol analyzers valuable for troubleshooting and for attackers conducting eavesdropping attacks. Encryption protocols such as TLS are critical defenses against this risk.
