# PCI Compliance

> Implement PCI DSS compliance requirements for secure handling of payment card data and payment…

PCI Compliance gives you a practical path through PCI DSS: the 12 core requirements, the four compliance levels, and the SAQ types, while showing you how to shrink your audit scope dramatically. The core strategy is to keep card data off your servers entirely through hosted payments and tokenization, dropping you from a 300-question SAQ D to a roughly 20-question SAQ A. It includes the encryption, access control, audit logging, and data-minimization patterns that turn 'compliant' from a checklist into working code.

## Use cases
- Building a payment-processing system that handles card data
- Reducing PCI scope from SAQ D toward SAQ A
- Implementing tokenization so PAN never hits your server
- Encrypting cardholder data at rest and in transit
- Setting up audit logging for all cardholder-data access
- Preparing for a PCI DSS self-assessment

## Benefits
- Cut audit cost and effort by keeping card data off your systems
- Avoid the most common violations like storing CVV or unencrypted PAN
- Build customer payment trust with the right security signals
- Make compliance enforceable in code, not just documented on paper

## What’s included
- The 12 PCI DSS requirements mapped to six defense categories
- Scope-reduction guidance across SAQ A, A-EP, and D
- Tokenization patterns: processor tokens and custom AES-256 vaults
- AES-256-GCM at-rest encryption and TLS 1.2+ in-transit config
- Role-based access control with a require-PCI-access decorator
- Append-only PCI audit logger and prohibited-data validation

## Who it’s for
Engineering teams handling payment card data who need to meet PCI DSS while keeping their compliance scope and audit cost as small as possible.

## How it runs
The gap between a 20-question self-assessment and a 300-question audit is one architecture decision. This skill shrinks PCI scope first, then locks down whatever card data is left.
1. Map the card data flow and pick the smallest possible PCI scope: a hosted payment page lands you in SAQ A (about 20 questions), an embedded Stripe.js form in SAQ A-EP (about 180), server-side card handling in SAQ D (about 300 plus annual pentest and QSA audit), so scope reduction is the first decision, not an afterthought.
2. Enforce data minimization: CVV, full track data and PIN are never stored, PAN is masked to first 6 plus last 4 in every log through the sanitize routine, and a storage validator raises before any prohibited field can reach the database.
3. Tokenize: card data turns into a token client-side, the server only ever sees tok_/pm_ identifiers, and the database stores customer_id plus payment_method_id, nothing else; if a custom vault is unavoidable it runs AES with cryptographic random tokens, never the standard random module.
4. Encrypt both states: AES-256-GCM with a random nonce for data at rest, TLS 1.2+ with secure, httponly, samesite cookies for data in transit.
5. Gate and record access: a pci_access role decorator blocks unauthorized reads, and every cardholder data access is written to an append-only audit log with timestamp, user, resource, action, result and IP, retained per Requirement 10.
6. Close with the 6-category compliance checklist (network security, data protection, vulnerability management, access control, monitoring, policy) and sweep the known violation list, stored CVV, unencrypted PAN, default passwords, missing logs, before any assessment.

## FAQ
### We already use a hosted checkout like Stripe, is this still relevant?
Yes, that's exactly the strategy it codifies: hosted payments plus tokenization keep PAN off your servers and qualify you for SAQ A territory. The skill helps you confirm the remaining scope, the roughly 20 questions you still answer, and implement the controls behind them.

### How does it actually shrink the audit from 300 questions to about 20?
By eliminating cardholder-data storage: tokenization patterns (processor tokens or a custom AES-256 vault) mean your systems never hold raw PAN, which moves you from SAQ D toward SAQ A. What remains: access control, audit logging, prohibited-data validation, ships as code patterns, not just policy documents.

### Does following it make me officially PCI certified?
No. It prepares the self-assessment and implements the technical controls, but formal validation: the SAQ attestation or a QSA audit, depending on your level, is a process you complete with your acquirer. Certification is paperwork plus evidence; this skill builds the evidence.
