Mike, a security engineer, was recently hired by BigFox Ltd. The company recently experienced disastrous DoS attacks. The management had instructed Mike to build defensive strategies for the company's IT infrastructure to thwart DoS/DDoS attacks. Mike deployed some countermeasures to handle jamming and scrambling attacks.
What is the countermeasure Mike applied to defend against jamming and scrambling attacks?
To defend against jamming and scrambling attacks, the countermeasure Mike applied was likely the implementation of cognitive radios in the physical layer. Cognitive radios are advanced technological systems capable of sensing their environment, including detecting signals from other RF devices. They can dynamically adjust their operating frequencies in response to the sensed environment, making them highly effective in mitigating the impacts of jamming and scrambling attacks. By utilizing cognitive radios, the system becomes flexible and resilient, thus providing a robust defense against such disruptive attacks.
D. Implement cognitive radios in the physical layer. Cognitive radios can sense the environment, sense other RF devices' signals, and use different frequencies in response to the sensing results. This makes the device very flexible in terms of being able to adjust to different environments and also to be able to detect and evade jamming or scrambling attacks. By deploying cognitive radios, Mike can mitigate the effects of DoS/DDoS attacks that use jamming or scrambling techniques.
