Anti-DDoS for gaming and ISPs: protect legitimate traffic

Useful mitigation starts by understanding protocols, ports, normal patterns, capacity and response procedures.

Decision guide · Network security

What Anti-DDoS protection do I need for gaming or network services?

There is no single rule for every attack. Document published services, protocols and ports, normal and peak traffic, observed vectors, prefixes, ASN and latency tolerance. ZGH can integrate monitoring, local mitigation and network capabilities, but coverage, thresholds, automation and upstream escalation must be defined for each project.

Use cases

Gaming and legitimate UDP

Servers where indiscriminate UDP blocking would interrupt the actual service.

ISPs and BGP networks

Operators that need to protect prefixes and coordinate controlled announcement or diversion policies.

Public platforms

Exposed services where availability, reputation and user experience depend on fast response.

Decision criteria

Layered design

Mitigation should combine evidence, local controls and network coordination without confusing intense traffic with an attack.

  1. Baseline

    Packets per second, bits per second, flows, countries, protocols and normal time windows.

  2. Classification

    Separate volumetric, state exhaustion, amplification and application-specific attacks.

  3. Local mitigation

    Filters and policies targeted to the observed vector while preserving required traffic.

  4. Upstream capacity

    Define when an attack exceeds local capacity and which escalation mechanism is used.

  5. Operations

    Alerts, owners, change authorization, evidence, communication and rollback.

Explicit scope

Coverage that must be documented

Components to evaluate

  • Network monitoring and alerts
  • Protocol or service-specific policies
  • Local mitigation according to architecture
  • BGP integration where applicable
  • Event logs and evidence
  • Defined technical escalation

Do not assume without confirmation

  • Maximum absorption capacity
  • Included and excluded vectors
  • Always-on or on-demand mitigation
  • Application-layer protection
  • Target response time
  • Contracted upstream scrubbing or mitigation

AS263702 and its interconnections can be reviewed on PeeringDB and BGP.Tools. Network evidence does not replace the contractual definition of a specific protection service.

FAQ

Anti-DDoS questions

Should I block all UDP?

Not when the service requires legitimate UDP, as many games, voice and streaming platforms do. Mitigation must separate required traffic from the attack vector.

Does Basic Anti-DDoS cover every attack?

It should not be read as unlimited coverage. Vectors, capacity, thresholds and escalation must be reviewed per service.

Is BGP required?

It depends on architecture and prefix control. BGP can coordinate announcements or diversion in some scenarios, while others do not require it.

Next step

Design mitigation from real traffic

Share target prefixes or service, protocols, ports, normal peak, previous captures or events and current architecture. We can then define staged protection.
