Features four different modes and rulesThe project can be configured in four modes, Sniffer mode, Packet Logger mode, Network Intrusion Detection System (NIDS) mode, as well as the Inline mode. Additionally, Snort comes with predefined rules that can be downloaded from the project’s website, created by the community or by the Snort developers.
The most widely deployed IPS/IDS technologyDespite the fact that it runs from the command-line, Snort isn't very hard to use, but there are a lot of options for you to play with. It successfully combines the benefits of anomaly-based inspection, signature and protocol, making it the most widely deployed IPS (Intrusion Prevention System) and IDS (Intrusion Detection System) technology.
Supported operating systems and availabilityAs it’s available for download as a universal sources archive, Snort is officially supported under numerous GNU/Linux distributions, but it officially supports, with binary packages, the Fedora, CentOS, FreeBSD and Microsoft Windows operating systems. Both 32-bit and 64-bit architectures are supported at this time.
Getting started with SnortSnort can be easily installed on numerous GNU/Linux flavors, as it is available for download from the default software repositories of popular Linux kernel-based operating systems. Gettings started documentation can be found on the project’s page, covering a vast amount of questions related on how to setup Snort on Debian, openSUSE, Fedora, CentOS, FreeBSD and NetBSD OSes.
