Detecting Multi-Stage Attacks on AWS: A Guide to Cross-Service Signal Correlation
AWS, Wednesday, August 26th, 2026
AWS explains how correlating signals across security services and business context reveals multi-stage attacks single alerts miss.
A single alert from one security service tells you something happened; read alongside activity from other services and your own business context, it tells you whether that something is part of a multi-stage attack.
The post walks through a short illustrative sequence: an identity calls GetCallerIdentity from a source address it has not used before, and within minutes further activity follows. Individually these events are unremarkable, which is why they often pass unexamined.
The guide covers how to correlate signals across AWS security services so the pattern becomes visible, and how business context turns an ambiguous sequence into a confident determination.
