Hi all... I'm new to this list so if this has been answered already I apologize... BUT Here goes... For the past several weeks we have been the victim of several High Broadcasts Attacks to our campus. Our firewall gets inundated and basically shuts down all other traffic both inbound and outbound,,, thus appearing as if the network is down.. In fact that is what gets reported to our help desk. Sometimes these attacks last for 10 20 minutes... other times several hours. Is anyone else experiencing these symptoms and what are you doing to combat same???? After several hours of investigation, we have identified and picked up a student computer to investigate whether the Windows Updates are current and if our (campus license) Norton anti Virus is up to date. Does anyone have any automated tools that would help id and quarantine any such computer?// The broadcast traffic is through the roof!!! :-( thanks Ralph Fasano Associate VP Office Of Information Technology Rhode Island School of Design rfasano () risd edu ********** Participation and subscription information for this EDUCAUSE Discussion Group discussion list can be found at http://www.educause.edu/groups/.
