>> I see on CNN's web site, http://www.cnn.com that one of the United >> States largest web page hosting services, WebCom, had network >> problems this past weekend which were caused by a TCP/IP SYN >> attack that was traced through PSINET, to CA*NET, then to BC NET. > We have now installed filters on our routers which will not permit >any packet to leave them if it does not have a source address which we >own and which we advertise a valid route for. I suggest >that all other BCNet clients take this incident as a warning and >similarly tighten security on their routers if they have not already >done so. Instructions for doing this on Cisco, Bay and Livingston routers are available at http://www.mtiweb.com/isp in the "Security Info" section. I recommend that BC-Net alert all customers that they need to install these filters to make them a less desirable site for launching hacker-attacks. -- Michael Dillon - Internet & ISP Consulting Memra Software Inc. - Fax: +1-604-546-3049 http://www.memra.com - E-mail: michael@memra.com
