Amazon Web Services (AWS) is a large cloud service provider with over 200 services, but this vast ecosystem introduces significant security and incident response challenges. The complexity of AWS, including its diverse logging formats and dynamic nature, complicates the identification and management of security incidents. Organizations face sophisticated attacks like ransomware and data exfiltration, emphasizing the need for a proactive and well-structured approach to incident response in AWS.

This guide aims to empower security teams to address incidents in the cloud effectively by covering:

• An overview of key AWS services and log sources relevant to incident response, including AWS CloudTrail, AWS, CloudWatch, and VPC Flow Logs.
• Strategies for responding to incidents in services such as EC2, EKS, ECS, Lambda, and S3.
• Best practices for automating incident evidence collection and analysis to reduce response times and improve accuracy.
• Guidance on forensic analysis tailored to the complexities of AWS environments.
• Strategies for addressing challenges such as data volatility, cross-account operations, and multi-cloud complexity.
