AWS guide details detecting multi-stage attacks using cross-service signal correlation
Key points
- Correlate signals from multiple AWS security services.
- Integrate business context for comprehensive attack detection.
- Examples provided use Amazon CloudWatch Logs Insights.
- Guide targets security engineers and operations teams.
Understanding Multi-Stage Attack Detection
AWS released a guide focusing on how security teams can detect multi-stage attacks by correlating security signals across different AWS services. Instead of addressing individual alerts, this method aims to identify a sequence of malicious activities by combining data from various sources with an organization's specific business context.
An example scenario involves an unfamiliar identity making an initial call, followed by failed access attempts across services, and then a large data exfiltration to a newly registered domain. While services like Amazon GuardDuty might flag parts of this, correlating these events provides a unified view of the attack sequence.
Leveraging AWS Detection Services
The guide emphasizes building upon existing AWS detection services, which cover common threats. These services include Amazon GuardDuty for analyzing activity across CloudTrail, VPC Flow Logs, DNS logs, and S3 data events; Amazon Detective for visualizing relationships between resources and findings; AWS Security Hub for aggregating security findings; and Amazon Security Lake for centralizing security data in OCSF format.
Building Correlation and Automation
The guide provides practical examples that can be implemented using Amazon CloudWatch Logs Insights. It also describes how these correlation methods can be scaled into automated pipelines for continuous monitoring and response. This allows security teams to move beyond reactive alert triaging to proactive detection of complex attack patterns.

Reporting from
AWS published a guide for security engineers on detecting multi-stage attacks by correlating signals from various AWS security services with business context. This approach helps identify attack sequences rather than triaging individual findings, improving overall security posture. The guide provides examples using Amazon CloudWatch Logs Insights and outlines how to build automated pipelines for correlation.
