Perform a bounded, read-only cloud security review. Produce findings, not edits, approval, certification, or a claim of compliance.
Review inputs
Read .github/copilot-instructions.md, 01-preparation/15-governance.md, the exact target, its baseline and proposed state, linked trust/data/identity boundaries, accepted ADRs, threat model, implementation handoff, operations plans, and any cited external evidence.
Threat model
Review only plausible paths relevant to the target:
- human, workload, pipeline, agent, privileged, and emergency identity compromise;
- authorization bypass, privilege escalation, cross-tenant or cross-environment access;
- data exfiltration, integrity loss, unsafe retention, logging exposure, and key compromise;
- public exposure, insecure API, event or message forgery, replay, and denial of service;
- dependency, package, container, artifact, infrastructure, pipeline, model, prompt, or data supply-chain compromise;
- prompt injection, poisoned grounding, excessive tool permissions, unsafe output, and autonomous consequential action;
- policy drift, unpatched vulnerability, unavailable security dependency, incident and recovery failure.
Workflow
- Resolve the exact target, baseline, environment, data class, identities, and trust boundaries.
- Trace entry points, assets, authority, data paths, management planes, dependencies, and failure/recovery paths.
- Identify existing preventive, detective, responsive, and recovery controls.
- Report only findings with a credible exploit or failure path and material consequence.
- Distinguish introduced, increased, reduced, exposed pre-existing, and unknown risk.
- For each finding provide severity, confidence, affected records, scenario, evidence, required control, validation, owner, and gate impact.
- Report evidence gaps separately from confirmed vulnerabilities.
Severity
Critical: credible path to catastrophic compromise or prohibited boundary; stop before proceeding.High: material security objective is plausibly unmet and needs resolution before the affected gate.Medium: meaningful weakness requiring an owned plan or explicit risk treatment.Low: bounded hardening item with limited impact.
Completion
Return scope, assumptions, findings ordered by severity, positive controls relied on, evidence gaps, required tests, owner roles, and gate impact. Remain read-only.
