AWS DevOps DevOps Monitoring, Testing & Deployment Strategies 5

Question 1

Which AWS service enables you to continuously assess EC2 instances for software vulnerabilities and unintended network exposure without deploying agents?

Amazon Inspector v2 uses agentless scanning for EC2 (via SSM) and container images to find CVEs and network reachability issues.
