What is Snort 3?

Snort 3 is a powerful network intrusion prevention system (NIPS) that provides real-time traffic analysis and packet logging. It is designed to detect and prevent attacks on a network, including denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks, as well as other types of malicious activity. Snort 3 is the latest version of the popular Snort system, which has been widely used for over two decades.

History of Snort

Snort was first released in 1998 by Martin Roesch, who is also the founder of Sourcefire, the company behind Snort. Since its initial release, Snort has become one of the most widely used NIPS systems in the world, with millions of downloads and a large community of users and developers.
