DDoS stands for Distributed Denial of Service, a malicious attempt to disrupt and suspend internet and network services. A well planned and executed attack of this kind could bring a network to its knees, destroy critical data or prevent a network being used until a fix is found. Most DDoS attacks are carried out remotely and aim to cause as much disruption to the target destination as possible. That target destination could be a home computer, a business server or a high profile Government or Military target. With DDoS attacks on the rise, it is important to understand the many layers and types of attack that are currently in the wild.
