How to block a "denial of service" attack
One of the more common methods of blocking a "denial of service" attack is to set up a filter, or "sniffer," on a networkbefore a stream of information reaches a site's Web servers. The filter can look for attacks by noticing patterns oridentifiers contained in the information. If a pattern comes in frequently, the filter can be instructed to block messagescontaining that pattern, protecting the Web servers from having their lines tied up.
