DOS PROTECTION
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.

PARAMETERS
These parameters are displayed:
◆ Echo/Chargen Attack – Attacks in which the echo service repeats
anything sent to it, and the chargen (character generator) service
generates a continuous stream of data. When used together, they
create an infinite loop and result in a denial-of-service.
