Mistake Clinic
Module-Specific Mistake Radar
| Mistake | Signal | Repair |
|---|---|---|
| Diagram equals reachability | Unexpected packet succeeds | Test effective routes |
| Container equals VM isolation | Host privileges exposed | Minimize runtime power |
| Managed equals secured | Customer IAM open | Apply shared responsibility |
| One policy layer | Alternate path bypasses | Layer identity and network controls |
| Logs after incident | Critical events absent | Design forensic readiness |
Practice Mistake Checks
Verify privilege, memory evidence, patch state, flows, DNS/TLS/proxy boundaries, IAM escalation, metadata, secrets, runtime privileges, RBAC, admission, network policy, quotas, durable logs, containment, and revocation.
Required evidence
Submit authorized topology, effective policy and reachability, commands and configuration, attack and denial evidence, correlated audit events, containment, regression or policy gate, and residual risk. Redact all credentials and sensitive identifiers.
Oral defense
Trace one path across host, network, cloud, and workload boundaries; identify the first effective control; demonstrate containment and credential revocation; and state the remaining trusted layer.
Source backbone
Use Building Secure and Reliable Systems, NIST SP 800-190, Kubernetes security docs, and official provider documentation.
