Understanding DDoS Protection: How Nellyx Keeps Your Servers Safe
Learn how DDoS attacks work and how Nellyx helps protect game servers from common attacks.
The Reality of DDoS Attacks
Distributed Denial of Service (DDoS) attacks are the number one threat to game servers. They’re common, devastating, and—frankly—anyone can launch one.
This guide explains how Nellyx protects you.
Types of DDoS Attacks
Layer 3: Network Attacks
These attack the infrastructure itself:
- ICMP Flood — Overwhelms network interfaces
- UDP Flood — Amplification attacks using DNS/NTP
- ** SYN Flood** — Exhausts connection tables
Layer 4: Transport Attacks
Targeting connection handling:
- TCP Flood — Bogus connection requests
- ACK Flood — Acknowledgment overload
Layer 7: Application Attacks
The most sophisticated—and dangerous:
- HTTP Flood — Looks like real traffic
- Login Requests — Targets authentication
- Game Protocol Exploits — Protocol-specific attacks
How Nellyx Protects You
Network-Level Protection
Our network filters attack traffic before it reaches your server:
Attack Traffic → Edge Filters →Clean Traffic → Your ServerFeatures:
- Automatic filtering — Designed to react quickly
- Layered mitigation — Different rules for different attack types
- Always-on coverage — Protection is enabled by default on supported services
Intelligent Detection
We use multiple detection methods:
| Method | Detects |
|---|---|
| Behavioral analysis | Anomalous traffic patterns |
| Signature matching | Known attack signatures |
| Rate limiting | Sudden traffic spikes |
| Geo-blocking | Unwanted regions |
Game-Specific Mitigation
Generic DDoS protection isn’t enough for game servers. We understand game protocols:
- Minecraft — Handle custom packet structures
- Rust — Protect against protocol exploits
- Valheim — Game-specific attack vectors
- Custom — Tailored rules for any game
What You Should Do
Enable Protection
All Nellyx servers include DDoS protection. No configuration needed.
Keep Software Updated
Outdated server software has known vulnerabilities:
# Update your server regularly
# Paper/Spigot
/download latest build
# Check for updates weeklyUse Strong Authentication
Don’t make it easy for attackers:
- Enable 2FA on all accounts
- Strong passwords (16+ characters)
- Rotate keys regularly
Monitor Your Server
Know what’s normal:
- Monitor player counts
- Track CPU/RAM usage
- Watch network in/out
- Set up alerts for anomalies
What Happens During an Attack
When an attack hits your server:
- Detection — Our systems identify attack within seconds
- Mitigation — Bad traffic filtered, good traffic passes
- Notification — You receive alert about the attack
- Analysis — Attack vector identified and blocked
You stay online. attackers move on.
Common Questions
Does protection slow my server?
No. Our filtering happens at the network edge—before traffic reaches your server.
What if there’s a huge attack?
Large attacks depend on the protocol, vector, and region involved. If you’re running a high-risk workload, contact support so we can recommend the right deployment profile.
Can I get targeted?
We’ve had cases where attackers specifically target servers. Our protection adapts in real-time.
Summary
DDoS attacks are part of running game servers. With Nellyx:
- ✓ Always-on protection on supported services
- ✓ Automatic filtering
- ✓ Game-specific mitigation paths
- ✓ Guidance for higher-risk deployments
Your server stays online. That’s the promise.
