Scope map

Lane What to master Common weak answer
Identity and access Resolve IAM policy, resource policy, SCP, permission boundary, session policy, and federation behavior. Stopping at an Allow statement while an explicit deny, SCP, boundary, or key policy still blocks access.
Logging and detection Use CloudTrail, CloudWatch, GuardDuty, Security Hub, Config, VPC Flow Logs, and alert routing. Turning on logs without retention, analysis, notification, or response.
Data protection Apply KMS, encryption, secrets, S3 controls, backup, retention, and classification requirements. Forgetting KMS key policy or cross-account decrypt permissions.
Network and infrastructure security Secure VPC paths, endpoints, security groups, NACLs, WAF, Shield, and private connectivity. Using public paths when private endpoint or scoped network access is required.
Incident response and governance Contain compromised credentials, isolate resources, preserve evidence, and automate remediation. Destroying evidence or rotating the wrong credential first.
