The problems caused by a DoS attack are as follows:
l Saturation of network resources
l Disruption of connections between two computers, thereby preventing communications between services
l Disruption of services to a specific computer
l Failure to access a Web site l Increase in the amount of spam
Which of the following can be used as countermeasures against DoS attacks?
