Denial-of-Service Attacks

Denial-of-service (DOS) attacks can occur when a large number of poorly formed requests are sent to servlets. You can reduce the impact of DOS attacks, but it is impossible to prevent them. If an attacker throws enough data at a server to continuously use all the available network bandwidth, it will crowd out legitimate traffic, regardless of how the software is configured. Denial of service can only be handled at an application server level. To configure to reduce the impact of denial of service attacks, refer to the security documentation for your application server.
