Stratus Red Team is an open source project that enables cloud security engineers to seamlessly emulate adversary behavior within sandboxed environments, abstracting the intricacies of infrastructure setup and teardown. Datadog Cloud SIEM provides real-time analysis of operational and security telemetry, along with curated out-of-the-box rules for detecting and responding to threats. By using Stratus Red Team and Cloud SIEM together, cloud security teams can enhance their threat detection capabilities against diverse AWS threats, improve resilience, and streamline the detection development and validation processes. Threat emulation enables cloud security teams to leverage their understanding of threat actor behaviors as a feedback loop for developing effective cloud-based detections. However, setting up and tearing down infrastructure introduces friction, highlighting the need for efficient tools like Stratus Red Team and Cloud SIEM.
