3-3-3 DoS Attack Prevention
A denial-of-service attack (DoS attack) is an attempt to make a computer
resource unavailable to its intended users. DoS attacks generally consist
of the concerted, malevolent efforts of a person or persons to prevent an
Internet site or service from functioning efficiently or at all, temporarily
or indefinitely. One common method of attack involves saturating the
target (victim) machine, in this case the router, with external
communications requests, such that it cannot respond to legitimate traffic,
or responds so slowly as to be rendered effectively unavailable.
