Sniffer

A sniffer is a tool used to monitor and analyze network traffic by capturing data packets transmitted over a network. Think of it as a cybersecurity investigator that listens in on the data traveling between devices, such as computers and servers, to identify issues, analyze performance, or detect unauthorized activity. Used ethically, sniffers help network administrators troubleshoot problems or enhance security. However, if used maliciously, they can intercept sensitive information like passwords or personal messages. Thus, sniffer tools are valuable for maintaining network health and security when employed responsibly.
