Detecting Multi‑Stage Attacks on AWS with Correlation
🔍 This post explains how correlating signals across AWS services and your business context reveals multi-stage attacks that single alerts miss. It outlines five attack phases and the three primary log sources—CloudTrail, VPC Flow Logs, and Route 53 Resolver logs—used to surface each phase. The guide emphasizes enabling and tuning AWS detection services such as Amazon GuardDuty, then layering custom queries that encode your environment-specific knowledge. It includes CloudWatch Logs Insights queries and operational guidance for thresholds, multi-account setups, and automating detection pipelines.
