Reconstructing distributed denial of service (DDoS) attack traffic used to mean combining data from multiple sources after the fact. AWS Shield Advanced attack flow logs change that—they capture traffic metadata during attacks so you can pinpoint sources, verify mitigations, and feed your existing analysis pipelines. Shield publishes logs to Amazon Simple Storage Service (Amazon S3), […]

Generative AI–based applications have grown in popularity in the last couple of years. Applications built with large language models (LLMs) have the potential to increase the value companies bring to their customers. In this blog post, we dive deep into network perimeter protection for generative AI applications. We’ll walk through the different areas of network […]

At Amazon Web Services (AWS), security is our top priority. Security is deeply embedded into our culture, processes, and systems; it permeates everything we do. What does this mean for you? We believe customers can benefit from learning more about what AWS is doing to prevent and mitigate customer-impacting security events. Since late August 2023, […]

Every day across the Amazon Web Services (AWS) cloud infrastructure, we detect and successfully thwart hundreds of cyberattacks that might otherwise be disruptive and costly. These important but mostly unseen victories are achieved with a global network of sensors and an associated set of disruption tools. Using these capabilities, we make it more difficult and […]

July 29, 2025: We updated the AWS DDOS Test Partner list. Distributed denial of service (DDoS) events occur when a threat actor sends traffic floods from multiple sources to disrupt the availability of a targeted application. DDoS simulation testing uses a controlled DDoS event to allow the owner of an application to assess the application’s […]

May 5, 2025: This post has been updated to reflect that the lowest allowable rate limit setting in AWS WAF rate-based rules has changed from 100 requests to 10. In this post, we explain what the three most important AWS WAF rate-based rules are for proactively protecting your web applications against common HTTP flood events, […]

Note: This blog post describes how to automatically update AWS WAF IP sets with the most recent AWS IP ranges for AWS services. This related blog post describes how to perform a similar update for Amazon CloudFront IP ranges that are used in VPC Security Groups. You can use AWS Managed Rules for AWS WAF […]

AWS Shield is a managed service that protects applications that are running on Amazon Web Services (AWS) against external threats, such as bots and distributed denial of service (DDoS) attacks. Shield detects network and web application-layer volumetric events that may indicate a DDoS attack, web content scraping, or other unauthorized non-human traffic that is interacting […]

In this blog post, I show you how to improve the distributed denial of service (DDoS) resilience of your self-managed Domain Name System (DNS) service by using AWS Global Accelerator and AWS Shield Advanced. You can use those services to incorporate some of the techniques used by Amazon Route 53 to protect against DDoS attacks. […]

When you build applications on Amazon Web Services (AWS), it’s a common security practice to isolate production resources from non-production resources by logically grouping them into functional units or organizational units. There are many benefits to this approach, such as making it easier to implement the principal of least privilege, or reducing the scope of […]
