Applications must manage excess capacity, bandwidth, or other redundancy to limit the effects of information flooding types of Denial of Service (DoS) attacks.

Description
In the case of application DoS attacks, care must be taken when designing the application so as to ensure that the application makes the best use of system resources. SQL queries have the potential to consume large amounts of CPU cycles if they are not tuned for optimal performance. Web services containing complex calculations requiring large amounts of time to complete can bog down if too many requests for the service are encountered within a short period of time. The methods employed to meet this requirement will vary depending upon the technology the application utilizes. However, a variety of technologies exist to limit, or in some cases, eliminate the effects of application related DoS attacks. Employing increased capacity and bandwidth combined with specialized application layer protection devices and service redundancy may reduce the susceptibility to some DoS attacks.
