Fine tuning Snort

["James Lay" <jlay () slave-tothe-box net>]

Hello All.

So I'm needing to fine tune snort a bit.  I get a high amount of FP's on
things like:

Emails with .jpg's:
[1:12798:3] SHELLCODE base64 x86 NOOP [**] [Classification: Executable
Code was Detected]

exe downloads from Windows Updates:
[1:15306:4] WEB-CLIENT Portable Executable binary file transfer
[1:2000419:12] ET POLICY PE EXE or DLL Windows file download

I'd rather not just comment out these rules....what are other folks doing
to minimize FP's?  Thank you.

James
