Breathe easily: protect your Linux box with Snort (iTWire)
[Posted September 10, 2007 by jake]
iTWire has an
overview of Snort,
the free intrusion detection system (IDS). "
Snort's third
operating mode – network intrusion detection – is when the
magic happens. Here, Snort actually pays attention to the network traffic
passing its electronic eyes and matches what it sees according to a
database of updatable signatures as well as any custom user-defined
rules. In this mode, Snort does for networks what anti-virus tools do for
filesystems."
