Securing wireless mobile nodes from distributed denial-of-service attacks

摘要

The current mobile devices have become smart and are increasingly being used for conducting business andrnpersonal activities. Also, there is increasing number of attacks targeting such mobile devices. The termrnmobile botnet refers to group of mobile devices that are compromised and controlled by the attacker thatrncan be used for generating distributed denial-of-service attacks. The security protocols that have beenrnproposed for wireless and mobile networks have several weaknesses that can be exploited by the attackerrnto obtain unauthorized access and generate attacks. Also, there is growing number of malicious applicationsrnthat are aimed to compromise smartphones and using them for generating different types of attacks. In thisrnpaper, we propose techniques to counteract distributed denial-of-service attacks on wireless mobile devices.rnWe describe the operation and architectural components of our model. We will show that our model is ablernto efficiently deal with the attacks by dropping the attack traffic before it targets the victim mobile node, canrnprevent the attack traffic at the upstream nodes, and also deal with the attack cases that involve mobility ofrnthe attacking and victim nodes.
