Techopedia Explains Snort

Snort is useful for developers or others working on different types of system troubleshooting.

The security tool has three different modes, as follows:

  • Packet sniffer
  • Consistent logging of network traffic to facilitate debugging
  • Active network intrusion handling system

Snort is built to detect various types of hacking and uses a flexible rules language to determine the types of network traffic that should be collected.

For Snort to work correctly, users must identify directories for use and perform calibrations to specify how the program should work in any of its three basic modes.
