Understanding DNS Flood Attack: What Is It and How to Protect Against It

In today’s digital age, cybersecurity threats continue to evolve, targeting critical components of online infrastructure. One such threat is the DNS flood attack, a type of Distributed Denial of Service (DDoS) attack aimed at overwhelming Domain Name System (DNS) servers. This blog post will explore what DNS flood attacks are, how they work, and what can be done to protect against them.
