A Practical Guide to DDoS Protection for Gaming
Gaming Industry DDoS Attack Status
The gaming industry is a heavily targeted sector for DDoS attacks. Unlike the financial industry, gaming attack motivations are more diverse -- from competitor malicious competition to player retaliation, from extortion to "demonstrating capability." In 2025, DDoS attacks against the gaming industry accounted for 31% of the global total, ranking first among all industries for the third consecutive year.
Attack Characteristic Analysis
| Characteristic Dimension | Data | Description |
|---|---|---|
| Attack frequency | 3-5 times/day (popular games) | Far above other industries |
| Latency tolerance | < 50ms (FPS games) | Extremely low latency requirement |
| Attacker sources | 40% from players themselves | Unique "player-vs-player" attacks |
| Tournament period attack volume | 500% surge | Esports tournaments are high-incidence periods |
| UDP traffic share | > 70% | Game protocols mostly based on UDP |
Gaming Industry Attack Characteristics
Protocol-Layer Attacks
Game servers typically use custom UDP protocols for communication. Attackers exploit the characteristics of these protocols to launch targeted attacks:
Game Protocol Flood
Forging large numbers of game login, movement, or combat requests. Since request formats are identical to normal game traffic, traditional protection systems struggle to distinguish them.
UDP Reflection Attacks
Using game servers as reflectors to launch amplification attacks. Game protocol responses are typically larger than requests, providing some amplification effect.
Connection Exhaustion Attacks
Exhausting server connection pools through massive forged connections. Game servers typically have connection limits; once exhausted, new players cannot connect.
Application-Layer Attacks
| Attack Type | Target | Impact | Difficulty |
|---|---|---|---|
| Login server attacks | Authentication interface | Prevents player login | Medium |
| Matchmaking system attacks | Match queue | Disrupts matchmaking experience | Medium |
| Leaderboard manipulation | Ranking interface | Manipulates leaderboard data | Low |
| Chat server attacks | Chat system | Social features disrupted | Low |
| API gateway attacks | Game service API | Overall service degradation | High |
Player-vs-Player Attacks
Real-Time Protection Needs
Latency Sensitivity
Different game types have significantly different latency tolerance:
| Game Type | Acceptable Latency | Protection Requirement | Description |
|---|---|---|---|
| FPS/Fighting | < 50ms | Extremely high | Millisecond-level latency affects operation precision |
| MOBA/RTS | < 80ms | High | Latency affects skill timing |
| MMORPG | < 150ms | Medium-High | Latency affects combat and interaction experience |
| Turn-based/Card | < 300ms | Medium | Relatively tolerant of latency |
Core Protection Metrics
| Metric | Target Value | Description |
|---|---|---|
| Detection latency | < 5 seconds | Time from attack detection to response |
| Scrubbing latency | < 10ms | Additional latency introduced by traffic scrubbing |
| False positive rate | < 0.01% | Proportion of normal player traffic falsely blocked |
| Recovery time | < 30 seconds | Time from attack start to service recovery |
Anycast Deployment Strategy
Why the Gaming Industry Needs Anycast
Traditional single-point deployment has obvious bottlenecks when facing large-scale DDoS attacks. Anycast networks broadcast the same IP address across multiple global nodes, distributing attack traffic to the nearest nodes for processing.
Deployment Architecture
Players → Anycast Edge Nodes → Traffic Scrubbing → Game Server Cluster
Key Configuration Points
- Node selection: Choose Anycast node locations based on player distribution, ensuring major player groups have nearby node coverage
- BGP routing optimization: Ensure normal traffic routes to optimal nodes, avoiding routing oscillation
- Session persistence: Game long connections need session persistence support to avoid connection interruption from scrubbing node switches
- Protocol optimization: Apply special optimization for UDP game traffic to reduce latency introduced by scrubbing
Case Studies
Major MOBA Game Protection Case
A globally renowned MOBA game frequently suffered DDoS attacks during tournament periods, causing match broadcast interruptions and severely degraded player experience. After deploying the Hiddos protection solution:
| Metric | Before Deployment | After Deployment | Improvement |
|---|---|---|---|
| Attack detection time | 45 seconds | 3 seconds | 93% |
| Scrubbing-introduced latency | 30ms | 5ms | 83% |
| Service availability | 97.5% | 99.99% | +2.49% |
| Tournament period interruptions | Multiple | Zero | 100% |
FPS Game Global Deployment Case
An FPS game needed to provide low-latency gaming experience for global players. Hiddos provided protection services through 42 global Anycast nodes:
- Global average latency reduced by 35%
