Securing Your Network Against Denial of Service (DoS) Attacks
Denial of service (DoS) attacks saturate networks and servers with useless calls for information. Attackers use multiple sites to make distributed attacks on one or more networks, servers, or web sites. Servers subjected to this sort of jamming either crash or become too busy to be of use when a network becomes flooded. Not only is the server compromised for communication, but it also becomes unavailable as a tool for tracing the attacks.
Caution
Always observe precautions to protect the security and integrity of the registry on XenApp. For information about backing up the registry and other precautions, refer to Microsoft documentation. Editing registry settings, other than those discussed in this chapter, can corrupt your server configuration and is not supported by Citrix.
