DNS security is an essential component of overall security for any organization because DNS is often the first point of contact when users access the internet, and it is a primary method for cyber attackers to infiltrate networks. DNS security ensures that the DNS infrastructure is resistant to attacks, such as cache poisoning and distributed denial of service (DDoS) attacks, preventing attackers from intercepting, tampering with, or redirecting DNS traffic. Additionally, DNS security provides visibility into the traffic that goes through the network, allowing security teams to identify both legitimate and malicious activities that occur in the network, and enabling them to quickly detect and respond to security incidents.
