ROTECTION

Use the Security > DoS Protection page to protect against denial-of-service

(DoS) attacks. A DoS attack is an attempt to block the services provided by

a computer or network resource. This kind of attack tries to prevent an

Internet site or service from functioning efficiently or at all. In general, DoS

attacks are implemented by either forcing the target to reset, to consume

most of its resources so that it can no longer provide its intended service,

or to obstruct the communication media between the intended users and

the target so that they can no longer communicate adequately. This section

describes how to protect against DoS attacks.
