What is DDoS Protection? Complete Guide for Game Server Owners
Everything game server owners need to know about DDoS protection. Attack types, how mitigation works, and why enterprise protection matters for Minecraft and FiveM servers.
What is a DDoS Attack?
A Distributed Denial of Service attack floods your server with malicious traffic from thousands of devices. Your server's network connection is overwhelmed and legitimate players can't connect. Game servers are frequent targets because competitors want to drive players away from rival communities.
Common Attack Types
TCP SYN flood: exhausts your server's connection tracking table. UDP flood: saturates bandwidth with garbage packets. Slowloris: holds connections open indefinitely. Amplification attacks: exploits game query protocols (Minecraft port 25565 is particularly vulnerable). Layer 7 attacks: mimics real game traffic to bypass basic filters.
How Mitigation Works
Traffic passes through scrubbing centers that analyze each packet for malicious patterns. Legitimate game traffic is forwarded to your server. Attack traffic is dropped at the network edge. This process adds <1ms latency. Modern mitigation uses machine learning to distinguish real player traffic from botnet attacks.
Why Game-Aware Filtering Matters
Generic DDoS filters often block legitimate game traffic because they don't understand game protocols. FiveM heartbeat packets look different from Minecraft login packets. Game-aware filtering recognizes normal player behavior for each game, reducing false positives that block real players. CyberNex includes 17 Tbit game-aware filtering on all plans.
What to Do During an Attack
Don't restart your server — this can make things worse. Check your control panel for attack alerts. Mitigation activates automatically within seconds. Most attacks subside within 15-30 minutes. If an attack persists, contact our emergency support via Discord.
Frequently Asked Questions
Is DDoS protection really free?
Yes. Every CyberNex plan includes enterprise DDoS mitigation at no extra cost. It's built into our network infrastructure, not a paid addon.
Can DDoS protection fail?
Enterprise protection with sufficient capacity (17 Tbit) handles 99.9% of attacks. Extremely large botnet attacks (>10 Tbit) may cause brief disruption. Our network engineers can deploy custom mitigation rules for persistent attacks.
