Roles vs stored credentials (use roles!) 2. SCP (caps an account) vs permissions boundary (caps one user) 3. Encryption specialists: KMS / Secrets Manager / ACM 4. Detection: GuardDuty (threats) vs Inspector (vulnerabilities) vs Macie (data) 5. Edge: WAF (web exploits) vs Shield (DDoS) Plus the identity split: Cognito (customers) vs IAM Identity Center (workforce). 🎓 SCORING Got 9+ right (~70%)? Your security knowledge is in good shape.
