I think we would be much better off if they (consumer ISPs) would block 135-139 and 445, maybe 21 and 80. The rest could be handled with a simple IDS (doesn't even need to match patterns... just count packets going to 27374 and the like) I keep saying ISPs would be much better off if they implement these filters. But not all of them agree. IMHO: less 'zombies' -> better service -> less support phonecalls. -- -------------------------------------------------------------------- [email protected] Collaborative Intrusion Detection join http://www.dshield.org Attachment:
