Infrastructure Compliance Auditor

Cross-cutting infrastructure security audit across ALL compliance frameworks. Replaces manual Vanta-style checks with deterministic, repeatable, evidence-generating infrastructure audits covering cloud, DNS, TLS, endpoints, access control, network, containers, CI/CD, secrets, logging, and physical security. Maps 250+ controls to 10 standards (SOC 2, ISO 27001, HIPAA, GDPR, PCI-DSS, NIS2, DORA, NIST CSF, FedRAMP, CCPA) with severity-weighted scoring.

Core Capabilities

• 11 audit domains — cloud (AWS/Azure/GCP), DNS, TLS/SSL, endpoints, access control, network, container/K8s, CI/CD, secrets, logging/monitoring, physical security
• 250+ controls — each with a check ID, severity rating, and multi-framework mapping
• Framework mapping — collect-evidence-once, map-to-many strategy across 10 standards
• Deterministic scoring — severity-weighted per-domain and overall scores (0-100) with an audit-readiness rating
• Evidence generation — JSON and markdown reports suitable for auditor consumption

When to Use

Reach for this skill on: "infrastructure audit", "cloud security audit", "infrastructure compliance", "DNS security audit", "TLS audit", "endpoint security", "access control audit", "network security assessment", "infrastructure security", "cloud compliance", "Vanta alternative", "compliance automation", "security posture assessment", "hardware security keys", or "YubiKey compliance".

Clarify First

Before running the audit, confirm these inputs. If any is unknown or vague, ASK — do not assume:

• Audit domains — which of the 11 (cloud, DNS, TLS, endpoints, access, network, container, CI/CD, secrets, logging, physical) are in scope (determines which checks run)
• Target frameworks — which standards to map findings to (SOC 2, ISO 27001, HIPAA, PCI-DSS, NIS2…) (drives the control mapping and report)
• Infrastructure config — the JSON describing actual state, including cloud provider (AWS/Azure/GCP) (the checks and CIS baseline depend on it)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the audit report.

Quick Start

Tools

Tool	Purpose	Input
infra_audit_runner.py	Full infrastructure audit across all 11 domains	JSON config describing infrastructure

Scope & Limitations

In Scope:

• Infrastructure security audit across 11 domains: Cloud, DNS, TLS/SSL, Endpoints, Access Control, Network, Containers/K8s, CI/CD, Secrets, Logging/Monitoring, Physical Security
• Framework mapping to 10 compliance standards: SOC 2, ISO 27001, HIPAA, GDPR, PCI-DSS, NIS2, DORA, NIST CSF, FedRAMP, CCPA
• 250+ individual control checks with severity-weighted scoring
• DNS security validation including SPF, DKIM, DMARC, DNSSEC, CAA, MTA-STS, and subdomain takeover risk
• Access control audit covering IdP, SSO, MFA, FIDO2/hardware keys, PAM, RBAC, service accounts, SSH keys, API keys, and Zero Trust
• Evidence-generating reports in JSON and markdown formats for auditor consumption

Out of Scope:

• Actual penetration testing, vulnerability scanning, or active exploitation -- this skill performs configuration-based assessment, not active testing
• Cloud provider API calls or live infrastructure scanning -- the tool works with JSON configuration input describing your infrastructure state
• Compliance certification or attestation -- this skill identifies gaps but does not replace formal SOC 2, ISO 27001, or PCI-DSS audits
• Application security testing (SAST/DAST) beyond CI/CD pipeline configuration checks
• Compliance program management, policy writing, or governance documentation

Important Notes:

• SOC 2 2026 best practices demand real-time monitoring dashboards flagging control deficiencies within 48 hours; periodic spot-checks are no longer sufficient
• Zero Trust architecture is increasingly expected across all frameworks; perimeter-based security alone is insufficient for SOC 2, ISO 27001, and NIS2
• Compliance automation platforms (Drata, Vanta, Sprinto) complement but do not replace the deterministic checks this tool provides
