A company recently experienced multiple DNS DDoS attacks, and the information security analyst must provide a DDoS solution to deploy in the company's data center. Which of the following would BEST prevent future attacks?
A.
Route the queries on the DNS server to 127.0.0.1.
B.
Buy a UTM to block the number of requests.
C.
Call the internet service provider to block the attack.
A sinkhole is a router designed to accept and analyze attack
traffic. Sinkholes can be used to do the following:
Draw traffic away from a target
Monitor worm traffic
Monitor other malicious traffic
A sinkhole is a solution to prevent future DNS DDoS attacks by rerouting malicious traffic away from the target network to a separate, isolated network or device. This reduces the amount of traffic that reaches the target network, thus reducing the potential impact of the attack. This is a preferred solution as it does not rely on the Internet Service Provider (ISP) to block the attack, but rather it is managed internally by the organization, providing greater control and visibility over the mitigation process.
