AWS Incident Response: From Preparation Through Post-Incident Review

AWS incident response differs from on-premises work because shared responsibility limits your scope to identities, configurations, data and workloads, and because most incidents start with valid credentials. Containing a compromised principal therefore often matters more than isolating a host. Many AWS resources are short-lived, such as Auto Scaling instances or Fargate tasks, so evidence capture must be prepared ahead of time and executed quickly. Since response steps can be automated through the CLI, Lambda or Systems Manager, the article warns that over-broad permissions create the same risk in automation. The guide frames its lifecycle around NIST SP 800-61 Revision 3 and the AWS Security Incident Response Guide, and includes CLI-based examples such as a restricted responder role and CloudTrail and Athena queries for scoping activity.
