Snort is an open source network intrusion detection system, capable of
performing real-time traffic analysis and packet logging on IP networks.
It can perform protocol analysis, content searching/matching and can be
used to detect a variety of attacks and probes, such as buffer overflows,
stealth port scans, CGI attacks, SMB probes, OS fingerprinting attempts,
and much more.
Snort has three primary uses. It can be used as a straight packet sniffer
like tcpdump(1), a packet logger (useful for network traffic debugging,
etc), or as a full blown network intrusion detection system.
You MUST edit /etc/snort/snort.conf to configure snort before it will work!
Please see the documentation in /usr/share/doc/snort-18.104.22.168 for more
information on snort features and configuration.
