Using SmartDefense In this field... Do this... Max. Connections/Second from Same Source IP Type the maximum number of network connections allowed per second from the same source IP address. The default value is 100. Set a lower threshold for stronger protection against DoS attacks. Note: Setting this value too low can lead to false alarms. Welchia The Welchia worm uses the MS DCOM vulnerability or a WebDAV vulnerability. After infecting a computer, the worm begins searching for other live computers to infect. It does so by sending a specific ping packet to a target and waiting for the reply that signals that the target is alive. This flood of pings may disrupt network connectivity. You can configure how the Welchia worm should be handled. Chapter 9: Setting Your Security Policy 235
