Does anyone know of an "add-on" or PERL script that can do some "ciphering" for me and tell me what percentage of my bandwidth is generating alerts with SNORT? I have a snort server set-up on a SPANNED 100 MBS/Full-Duplex port that feeds the internal LAN of a large US Military installation. I absolutely LOVE SNORT, but now that I see all of the crazy stuff being thrown at us via the Net, I was wondering if there was a way to show what percentage of our bandwidth is literally being wasted by the amount of cmd.exe, code red, SQL Worm 1433 stuff etc. etc. that is coming in here and "banging" my firewalls. THANKS!!
Well, the first thing that comes to mind is to use MRTG on your router and firewall. Using that, measure the amount of incoming traffic from the router. Then measure the amount of traffic that "leaves" your firewall--If it goes thru your firewall, it should be legitimate traffic, right? Subtract number one from number two, and you should have a rough idea of how much 'wasted' bandwith you have. But of course, I haven't had my coffee yet--So I could be entirely crackheaded. :) Cheers! ----- Erek Adams Nifty-Type-Guy TheAdamsFamily.Net _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm _______________________________________________ Snort-users mailing list Snort-users () lists sourceforge net Go to this URL to change user options or unsubscribe: https://lists.sourceforge.net/lists/listinfo/snort-users Snort-users list archive: http://www.geocrawler.com/redir-sf.php3?list=snort-users
