Identify Managed Identity role assignment gaps (data plane vs management plane confusion), certificate policy misalignment, exportability risks, network connectivity issues, integrated CA credential over-scoping, and rotation race conditions between cert-manager and Key Vault auto-rotation. Output severity-labeled findings with evidence and remediation steps.</p>\n<h2>Lean operating rules</h2>\n<ul>\n<li>Check the Managed Identity (or Service Principal) role assignment on the Key Vault: the correct role is <code>Key Vault Certificate Officer</code> (data plane). Flag <code>Key Vault Contributor</code> as HIGH — it grants management plane access including vault deletion. Flag <code>Key Vault Administrator</code> as HIGH (full data plane + management).</li>\n<li>Verify whether Key Vault RBAC mode is enabled (<code>enableRbacAuthorization: true</code>). If legacy access policies are used instead of RBAC, flag as MEDIUM (harder to audit, no Azure AD Conditional Access integration).</li>\n<li>Review <code>exportable</code> in the Key Vault certificate policy. Flag <code>exportable: true</code> on certs used for cluster-internal mTLS as MEDIUM (private key unnecessarily extractable from Key Vault).</li>\n<li>Check Key Vault network access configuration: if <code>publicNetworkAccess: Disabled</code>, verify the AKS cluster has private endpoint access to the Key Vault and DNS resolution via private DNS zone. Flag missing private endpoint as MEDIUM.</li>\n<li>For integrated CAs (DigiCert, GlobalSign): verify the Key Vault has the CA integration configured and the credential secret is scoped to a minimum (single certificate profile, not account-wide).</li>\n<li>Review cert-manager <code>renewBefore</code> against the Key Vault certificate's auto-rotation policy to detect overlapping rotation windows. Flag simultaneous rotation triggers as MEDIUM.</li>\n<li>Label all findings as sampled configured-environment evidence, documentation-based, or inference.</li>\n</ul>\n<h2>References</h2>\n<p>Load these only when needed:</p>\n<ul>\n<li><a href=\"references/keyvault-certificate-issuer-operations.md\">Azure Key Vault Certificate Issuer Operations</a> — use for current service behavior, common failure modes, hard design rules, verification targets, and push-back conditions.</li>\n<li><a href=\"references/safety-checklist.md\">Safety checklist</a> — use for evidence labels, risk gates, mutation boundaries, approval rules, credential boundaries, and current-state caveats.</li>\n<li><a href=\"references/mcp-and-evidence.md\">MCP and evidence path</a> — use when choosing documentation-based evidence, sampled read-only evidence, or sanitized user evidence.</li>\n<li><a href=\"references/official-sources.md\">Official sources</a> — use when you need the detailed Microsoft documentation list or source notes.</li>\n<li><a href=\"references/workflow-and-output.md\">Workflow and output contract</a> — execution flow and final response contract.</li>\n</ul>\n<h2>Response minimum</h2>\n<ul>\n<li>Severity-labeled findings list (CRITICAL / HIGH / MEDIUM / LOW)</li>\n<li>Evidence source for each finding</li>\n<li>Specific resource name or field that caused the finding</li>\n<li>Recommended remediation with example Azure CLI command or policy snippet</li>\n<li>Overall Key Vault certificate issuer posture verdict</li>\n</ul>\n","files":[{"path":"metadata.json","sizeBytes":1378,"isText":true},{"path":"references/keyvault-certificate-issuer-operations.md","sizeBytes":5247,"isText":true},{"path":"references/mcp-and-evidence.md","sizeBytes":1553,"isText":true},{"path":"references/official-sources.md","sizeBytes":2241,"isText":true},{"path":"references/safety-checklist.md","sizeBytes":1784,"isText":true},{"path":"references/workflow-and-output.md","sizeBytes":1627,"isText":true},{"path":"SKILL.md","sizeBytes":3683,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
