Security and compliance guidance for Amazon ECS — "ECS was unable to assume the role", task role vs execution role, iam:PassRole, confused-deputy aws:SourceArn trust, Fargate vs EC2 shared responsibility, injecting Secrets Manager/SSM secrets (trailing-colon JSON-key gotcha), readonlyRootFilesystem / non-root / drop capabilities, ECS Exec governance, security-group-per-task, VPC endpoint policies, GuardDuty ECS Runtime Monitoring, ECR Inspector scanning, image signing, Fargate FIPS, or PCI/HIPAA/FedRAMP. Walks a discovery-driven 7-layer stack plus the AWS-canonical baseline and a 30/60/90 roadmap. Trigger even if "compliance" is never said — any ECS hardening, task-trust fix, or secrets-injection qualifies. Skip for EKS/Kubernetes (eks-security), GenAI/GPU security (ecs-genai), App Runner/Lambda, auditing a live estate's operational posture (ecs-operation-review — "audit my ECS security posture" matches both), or account-level security with no ECS angle.
