Continuous monitoring under FedRAMP 20x: Replacing annual assessments with persistent validation

Under legacy Federal Risk and Authorization Management Program (FedRAMP) Rev5, continuous monitoring meant monthly deliverables and annual assessments. Under FedRAMP 20x, it means persistent, automated validation where the status of your security posture is always known. In this post, we operationalize that model using AWS Security Hub, AWS Config conformance packs, Amazon GuardDuty, Amazon Inspector, and Sigma detection rules to build an always-on monitoring architecture.
