## Complete Skill Definition

# PCI-DSS v4.0 Specialist

Implement, assess, and maintain compliance with the Payment Card Industry Data Security Standard version 4.0 — the global standard for protecting cardholder data in payment processing environments. Covers CDE scoping, SAQ/ROC selection, gap assessment against all 12 requirements, scope reduction (tokenization, P2PE, segmentation), and the future-dated v4.0 controls that became mandatory March 31, 2025.

## Core Capabilities

- **Compliance assessment** — score against all 12 PCI DSS v4.0 requirements, identify gaps, and prioritize remediation (`pci_compliance_checker.py`)
- **Scoping & SAQ selection** — map the cardholder data environment, classify connected and security-impacting systems, and determine the correct SAQ type or ROC requirement (`pci_scope_analyzer.py`)
- **Scope reduction** — tokenization, P2PE, network segmentation, and outsourced/iFrame processing to remove systems from scope
- **v4.0 readiness** — MFA for all CDE access, 12-char passwords, payment-page script controls (6.4.3/11.6.1), anti-phishing, automated log review, targeted risk analysis
- **Infrastructure controls** — network segmentation, TLS/DNS, endpoint/POS, cloud (AWS/Azure/GCP), container, and API security; encryption key lifecycle and DUKPT

## When to Use

Trigger on: "PCI DSS", "payment card security", "cardholder data", "PCI compliance", "payment security", "PCI assessment", "SAQ", "ROC", "QSA", "credit card security", "payment processing security", "tokenization", "CDE scoping", or "merchant level compliance".

## Clarify First

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

- [ ] **Business model / payment flow** — how cards are accepted (e-commerce, terminal, P2PE, fully outsourced/iFrame) (determines the CDE scope and correct SAQ type)
- [ ] **Merchant / service-provider level** — annual transaction volume (sets the validation path: SAQ vs ROC)
- [ ] **CDE scope** — which systems store, process, or transmit cardholder data plus connected systems (drives which of the 12 requirements are in scope)

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 report.

## Quick Start

```bash
# Check PCI compliance status (JSON report)
python scripts/pci_compliance_checker.py --input controls.json --output compliance_report.json

# Compliance gap report for stakeholders (Markdown)
python scripts/pci_compliance_checker.py --input controls.json --format markdown --output gap_report.md

# Determine SAQ type / analyze CDE scope
python scripts/pci_scope_analyzer.py --input business_model.json --output scope_report.json
python scripts/pci_scope_analyzer.py --input business_model.json --format markdown --output scope_analysis.md
```

Run `--requirements 3,4,7,8` to scope the checker to specific requirements. Full tool detail, input JSON formats, and flag reference live in the tools reference below.

## References

Load the reference that matches the task — keep this file lean and pull detail on demand:

- **[references/requirements-and-changes.md](references/requirements-and-changes.md)** — PCI DSS overview, the 12 requirements deep-dive (objective + key sub-requirements + implementation guidance each), and the v4.0 changes / future-dated requirements summary. Read when implementing or explaining a requirement.
- **[references/pci-dss-requirements-guide.md](references/pci-dss-requirements-guide.md)** — tabular reference: every sub-requirement with testing procedures and v4.0 change status. Read when you need exact sub-requirement IDs or auditor testing procedures.
- **[references/scoping-and-assessment.md](references/scoping-and-assessment.md)** — CDE definition and system classification, scope reduction strategies, SAQ types + selection decision tree, assessment types (SAQ/ROC/AOC), and merchant/service-provider levels. Read when scoping or choosing a validation path.
- **[references/infrastructure-controls-and-roadmap.md](references/infrastructure-controls-and-roadmap.md)** — technical controls (segmentation, DNS/TLS, endpoint/POS, cloud, container, API, tokenization architecture, key management) and the 5-phase 12-month compliance roadmap. Read when building or planning the program.
- **[references/pci-infrastructure-security.md](references/pci-infrastructure-security.md)** — deep architecture: reference network diagrams, per-cloud build-outs, mPOS, e-commerce script controls, and Kubernetes manifests. Read when designing CDE infrastructure in detail.
- **[references/tools-validation-troubleshooting.md](references/tools-validation-troubleshooting.md)** — full tool capabilities, input JSON formats, CLI flag tables, validation checkpoints, troubleshooting table, and success criteria. Read when running the tools or validating an engagement.

## Scope & Limitations

**In Scope:**
- PCI DSS v4.0/v4.0.1 compliance assessment against all 12 requirements
- SAQ type determination based on business model and payment processing architecture
- CDE scoping with connected system and security-impacting system identification
- Technical control validation (encryption, access control, logging, network segmentation)
- Compliance scoring with per-requirement gap analysis and remediation priorities
- Scope reduction strategy recommendations (tokenization, segmentation, P2PE)

**Out of Scope:**
- Approved Scanning Vendor (ASV) vulnerability scans (requires PCI SSC-approved ASV vendor)
- Qualified Security Assessor (QSA) on-site assessment or Report on Compliance (ROC) generation
- Payment application security validation (PA-DSS / PCI SSF scope)
- PIN Transaction Security (PTS) device certification
- Card brand-specific program requirements (Visa, Mastercard, Amex each have additional program rules)
- Legal advice on contractual obligations with acquiring banks or card brands
- Real-time transaction monitoring or fraud detection

## Integration Points

| Skill | Integration |
|-------|------------|
| [infrastructure-compliance-auditor](../infrastructure-compliance-auditor/) | Validates network segmentation, TLS configuration, endpoint security, and logging controls that satisfy PCI DSS Requirements 1, 2, 4, 10, 11 |
| [nist-csf-specialist](../nist-csf-specialist/) | CSF functions map to PCI DSS requirements; use the control mapper to build unified control matrices for dual-compliance programs |
| [soc2-compliance-expert](../soc2-compliance-expert/) | SOC 2 CC6 (access), CC7 (operations), CC8 (change management) overlap significantly with PCI DSS; leverage shared evidence |
| [information-security-manager-iso27001](../information-security-manager-iso27001/) | ISO 27001 Annex A controls provide a management system framework supporting PCI DSS compliance |
| [nis2-directive-specialist](../nis2-directive-specialist/) | EU entities subject to both NIS2 and PCI DSS can map shared controls (encryption, incident response, access control) |
