Stopping attacks on game servers

I ran DDoS detection and defense for a game with 600 servers. On GCP, Cloud Armor handled DDoS protection.

Cloud Armor is GCP’s web firewall and DDoS protection service. It applies policies such as blocking attack sources and limiting request rates in front of the load balancer.

Game servers often use their own protocols rather than web (HTTP) traffic, so network-layer DDoS defense and firewall policy cleanup matter together.
