AWS Best Practices for DDoS Resiliency

Publication date: August 9, 2023 (Document revisions)

It’s important to protect your business from the impact of Distributed Denial of Service (DDoS) attacks, as well as other cyberattacks. Keeping customer trust in your service by maintaining the availability and responsiveness of your application is high priority. You also want to avoid unnecessary direct costs when your infrastructure must scale in response to an attack. Amazon Web Services (AWS) is committed to providing you with the tools, best practices, and services to defend against bad actors on the internet. Using the right services from AWS helps ensure high availability, security, and resiliency.

In this whitepaper, AWS provides you with prescriptive DDoS guidance to improve the resiliency of applications running on AWS. This includes a DDoS-resilient reference architecture that can be used as a guide to help protect application availability. This whitepaper also describes different attack types, such as infrastructure layer attacks and application layer attacks. AWS explains which best practices are most effective to manage each attack type. In addition, the services and features that fit into a DDoS mitigation strategy are outlined, along with how each one can be used to help protect your applications.

This paper is intended for IT decision makers and security engineers who are familiar with the basic concepts of networking, security, and AWS. Each section has links to AWS documentation that provides more detail on the best practice or capability.

AWS detects over a million DDoS attacks per year and mitigates thousands on a daily basis against our customers. According to our Shield Response team (SRT), the majority of customers who experience business impact from DDoS attacks have not implemented the recommendations in this guide.
