Zorluk: KolayEdge and DDoS Protection

A gaming company is deploying a new multiplayer gaming lobby API on AWS. The company needs to protect the API endpoint against distributed denial of service (DDoS) attacks at the network layer, and block malicious Layer 7 request patterns such as HTTP floods. Which combination of AWS services should a Solutions Architect recommend to meet these requirements? (Select TWO.)

  1. AWS WAF to analyze and block malicious application-layer (Layer 7) web requests.Cevap
  2. AWS Shield Advanced to provide automatic mitigation against distributed denial of service (DDoS) attacks at the network and transport layers (Layer 3 and 4).Cevap
  3. C
    Network Access Control Lists (NACLs) configured to dynamically track request rates and block IP addresses at the edge.
  4. D
    Security groups applied at the subnet level to filter out volumetric DDoS attacks.
  5. E
    AWS Shield Standard to inspect and block Layer 7 vulnerabilities such as SQL injection.

Cevap

The correct services are AWS WAF and AWS Shield Advanced.
To satisfy both requirements, the Solutions Architect should recommend AWS WAF and AWS Shield Advanced. AWS WAF protects the API endpoint at the application layer (Layer 7) by inspecting incoming request characteristics and implementing rate limits. AWS Shield Advanced protects resources against Layer 3 and Layer 4 volumetric attacks, ensuring infrastructure-level availability.

Adım Adım Çözüm

1
Analyze the requirement for blocking application-layer (Layer 7) attacks, such as HTTP floods.
Identify AWS WAF as the service designed to inspect HTTP/HTTPS payloads and execute rate-based blocking.
AWS WAF operates at Layer 7 and can inspect headers, query strings, and request rates.
2
Analyze the requirement for blocking infrastructure-layer (Layer 3 and 4) DDoS attacks.
Identify AWS Shield Advanced as the service designed to mitigate volumetric network-layer attacks.
AWS Shield Advanced offers tailored detection and automatic mitigation against L3/L4 DDoS attacks on endpoints.
