do you know about the Security Information Exchange? http://sie.isc.org/
has details.

here is one message, out of a flow of tens of thousands per second, from
SIE Channel 202, displayed in ASCII (which is not useful other than for
demos like this -- you'll want to write code in Python, Perl, or C to
actually process it.) i've anonymized the questioner IP, answerer IP,
and sensor ID (xxx, yyy, and zzz below), leaving only information that's
safely shared in public:
