Description
DoS is a condition when a resource is not available for legitimate users. When this occurs, the organization either cannot accomplish its mission or must operate at degraded capacity. To reduce the possibility or effect of a DoS, the application server must employ defined security safeguards. These safeguards will be determined by the placement of the application server and the type of applications being hosted within the application server framework. Limiting the number of POST requests to the maximum number of form fields on any given page within the hosted application is used to mitigate the DoS attack known as HashDOS. For DoD systems, this parameter must be set to 50 or less.
