By Brooke Paul Bay. DDoS attacks are a new variation on the theme of denial of service, and they pose a serious threat to any Internet-based enterprise, regardless of infrastructure redundancy or robustness. Any organization that uses the Internet must take immediate action. You must implement procedures and configurations that will prevent your resources from being used in an attack, as well as reduce the impact and facilitate a rapid response once an attack has been initiated.
DoS removes from service a given resource, such as a server or network, without permission.
Distributing the workload across hundreds or even thousands of systems is one of the best ways to accomplish an intensive task, such as a major DoS attack. Clearly, the challenge these attacks present is a serious one. While you alone can't do much to protect yourself, as a community we can improve the situation. Evolution of DDoS Attacks Setting up and initiating a DDoS attack doesn't take much expertise. New tools are generated regularly, freely available and easily obtained.
