While migrating to AWS, a company wants to detect security misconfigurations or unusual behavior and prioritize protective controls. Which AWS CAF security perspective capability addresses this need?

Threat detection is the correct answer because it directly involves identifying security misconfigurations, unusual behavior, and potential threats to prioritize protective measures. This capability focuses on continuous monitoring and analysis to detect anomalies that could indicate a security incident. Identity and access management focuses on controlling who can access resources and what actions they can perform, not detecting misconfigurations or unusual behavior. Platform engineering deals with designing and building the underlying infrastructure and services, which is a broader architectural concern. Availability and continuity management ensures systems remain operational and can recover from disruptions, but doesn't specifically address security misconfiguration detection.
