DoS attacks and countermeasures on network devices

Denial of service (DoS) attacks have been one of the major network security problems over the last decades. DoS attacks can usually be mounted on hardware devices such as routers and firewalls to send spoofing messages to the target network. Thus, methods for defeating such DoS attacks are highly related to the vulnerabilities in the hardware devices. In this paper, we investigate the potential attacks specific to the hardware infrastructure of the network and also categorize the countermeasures against DoS attacks that can be implemented on hardware devices. Moreover, we analyze the advantages of the emerging silicon physical unclonable functions and discuss the potential of integrating them into authentication methods in order to defend against DoS attacks.
