# 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, settle the inputs below. When one is missing or vague and would change the result, ask about it; when it wouldn't, use a sensible default and say which one you used.

- **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).

Ask about the two or three inputs that matter most for this request, not the whole list. If the user wants a result straight away, produce it and state your assumptions at the top.

## Quick Start

### Run Full Infrastructure Audit

```bash
python scripts/infra_audit_runner.py --config infrastructure.json --output audit_report.json
```

### Audit DNS Security for a Domain

```bash
python scripts/dns_security_checker.py --domain example.com --output dns_report.json
```

### Audit Access Controls

```bash
python scripts/access_control_auditor.py --config access_controls.json --output access_report.json
```

### Generate Compliance-Mapped Report

```bash
python scripts/infra_audit_runner.py --config infrastructure.json --frameworks soc2,iso27001,hipaa --format markdown --output compliance_report.md
```

## Tools

| Tool | Purpose | Input |
|------|---------|-------|
| `infra_audit_runner.py` | Full infrastructure audit across all 11 domains | JSON config describing infrastructure |
| `dns_security_checker.py` | DNS-specific security audit (SPF, DKIM, DMARC, DNSSEC, CAA, MTA-STS) | Domain name |
| `access_control_auditor.py` | Access control, MFA, SSO, PAM, RBAC audit | JSON config describing access controls |

## 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
