You can't stop a DDoS attack.. Some attackers have thousands of computers in a bot-net. Tell me what kind of security that would be able to stop it.
But lets be realistic here, people that get DDoS in the OT community usually originate from someone who is either "Mad bro / Jelly (Recently banned, stolen X, etc)", competitor, or just an asshole and will only be a single person. Maybe even has some of his friends joining in on the cancer so like 3 people sending over nine thousand worthless packets.You can't stop a DDoS attack..
