Daily AWS Interview Question Shorts #76 | How can you mitigate DDoS attacks? | Engineer Comrade

1. Restate the question:
How can you mitigate DDoS attacks?

2. Explaining each option:
A. Use AWS Shield: AWS Shield is a managed DDoS protection service provided by AWS. It helps protect web applications against large-scale and sophisticated DDoS attacks. Incorrect, because while AWS Shield is a correct answer, we haven't determined if it's the best one yet.

B. Use Security Groups: Security Groups are a network security feature in AWS that acts as a virtual firewall to control inbound and outbound traffic to a resource. Incorrect, because Security Groups are primarily used for network traffic filtering, not mitigating DDoS attacks.

C. Use NACLs: Network Access Control Lists (NACLs) are another network security feature in AWS that also controls inbound and outbound traffic to a resource. Incorrect, because NACLs are primarily used for network traffic filtering, not mitigating DDoS attacks.

D. Use IAM Roles: IAM Roles are used to manage access to AWS resources and services. Incorrect, because IAM Roles are not designed to mitigate DDoS attacks.

3. Deeper explanation of the correct option:
A. Use AWS Shield: AWS Shield is the correct answer because it is specifically designed to protect web applications against DDoS attacks. It provides real-time visibility into DDoS traffic, automatic mitigation of attacks, and the ability to access additional DDoS protection as needed. AWS Shield also integrates with other AWS services, such as AWS WAF and AWS CloudFront, to provide a comprehensive DDoS mitigation solution.
