Advanced DNS Protection: mitigating sophisticated DNS DDoS attacks

What this post added

Introduced the Advanced DNS Protection system, a new defense mechanism against sophisticated DNS-based DDoS attacks. This system complements existing DDoS defenses by leveraging a stateful mitigation platform called `flowtrackd` and a distributed, gossip-based threat intelligence sharing mechanism. It aims to address attacks that are difficult to mitigate with traditional fingerprinting methods, particularly randomized and DNS laundering attacks. New DNS-centric data points have also been added to the Network Analytics dashboard and GraphQL API.
