Security & Compliance Guide

This guide outlines the security architecture, compliance measures, and best practices in RichWP GrowRich, ensuring secure and privacy-compliant eCommerce operations on WordPress.

Security Architecture

Stateless Authentication System

RichWP GrowRich uses a fully stateless authentication system, eliminating server-side session storage to reduce vulnerabilities:

  • PASETO Token-Based Authentication:
    • Employs Platform-Agnostic Security Tokens (PASETO) as a secure alternative to JSON Web Tokens (JWT).
    • Tokens are self-contained, embedding all user data and permissions.
    • No server storage is required, avoiding session fixation risks.
    • Tokens can be retrieved from multiple sources: URL parameters, HTTP headers, or POST data.

PHP

// Token retrieval from multiple sources
$token = $this->get_token_from_globals() ??
         $this->get_token_from_constant() ??
         $this->get_token_from_headers() ??
         $this->get_token_from_url() ??
         $this->get_token_from_post();
  • Key Security Features:
    • HMAC-based key derivation using HKDF from WordPress salts.
    • Automatic token expiration with configurable timeframes.
    • Sequence-based invalidation to prevent replay attacks.
    • Secure storage of Stripe keys via AES-256-GCM encryption.

Anti-Abuse Protection

Proof-of-Work (PoW)

  • Requires client-side computational work to deter spam.
  • Adjustable difficulty (default: 4 leading zeros).
  • Challenges are time-bound (valid for 15 minutes).
  • Includes fallback handling for graceful degradation.

Rate Limiting

  • Limits magic link requests to 5 per 15 minutes per user/session.
  • Uses WordPress transients for automatic cleanup.
  • Implements IP-based and session-aware tracking.

Input Validation & Sanitization

  • All inputs are sanitized using WordPress core functions.
  • Strict email format validation.
  • Prepared statements to prevent SQL injection.
  • Output escaping and sanitization to protect against cross-site scripting (XSS).

Content Protection

Multiple Paywall Types

  • Hard Paywall: Completely blocks content.
  • Teaser Paywall: Truncates content with configurable word limits.
  • Blur Paywall: Obscures content using CSS.
  • Redirect Paywall: Automatically redirects to purchase pages.

Access Control

  • Real-time validation against the Stripe API.
  • Admin bypass for content creators.
  • Secure file serving with appropriate security headers.
  • Time-limited, single-use download tokens.

GDPR Compliance

Data Minimization

Zero Local Customer Data Storage

  • No customer data is stored in the WordPress database—all resides in Stripe.
  • User data is never persisted locally.
  • Authentication tokens are transient and self-contained.

Data Processing Principles

  • Purpose Limitation: Data is processed only for payments and access control.
  • Data Minimization: Only essential data is collected.
  • Storage Limitation: No long-term local storage.
  • Integrity & Confidentiality: Sensitive data is encrypted end-to-end.

User Rights Implementation

Right to Access

  • Transparent data usage explained in privacy communications.
  • Users can request data via the Stripe dashboard.
  • All access is logged for auditing.

Right to Erasure

  • Data is removable via Stripe customer deletion.
  • Tokens are invalidated immediately on account changes.
  • No local cleanup needed due to zero storage.

Right to Portability

  • Data export available through Stripe in machine-readable formats.
  • Users access data directly from Stripe.

Consent Management

Implied Consent

  • Consent is implied during the payment process.
  • Privacy policy and terms are clearly stated.
  • Users manage data via Stripe settings.

Cookie-Free Operation

  • No tracking or session cookies are used.
  • Stateless design eliminates cookie dependencies.
  • No cookie consent banner required for GDPR.

Payment Security

Stripe Integration Security

Secure API Communication

  • All communications use HTTPS.
  • API keys are encrypted at rest.
  • Webhooks are verified via cryptographic signatures.
  • Stripe ensures PCI DSS compliance.

Checkout Security

  • Stripe-hosted checkout keeps sensitive data off your server.
  • Supports Strong Customer Authentication (SCA).
  • Includes 3D Secure for fraud protection.
  • Automated chargeback handling.

Financial Data Protection

No Card Data Storage

  • Payment methods are tokenized by Stripe.
  • No sensitive data is stored locally.
  • Data is retrieved securely via Stripe API.

Compliance Standards

SOC 2 Type II

  • Security: Robust controls in place.
  • Availability: Stateless design ensures high uptime.
  • Processing Integrity: Accurate transaction handling.
  • Confidentiality: Strong data protection.
  • Privacy: Aligns with GDPR practices.

ISO 27001 Alignment

  • Systematic information security management.
  • Ongoing risk assessments.
  • Role-based and token-based access controls.
  • Strong cryptography for sensitive data.
  • Structured incident management.

Accessibility Compliance (WCAG 2.1)

  • Full keyboard navigation.
  • ARIA attributes for screen reader support.
  • AA-level color contrast ratios.
  • Clear focus indicators and logical tab order.

Security Best Practices

Implementation Guidelines

Environment Security

PHP

// Always use HTTPS in production
define('FORCE_SSL_ADMIN', true);
define('FORCE_SSL_LOGIN', true);

// Secure WordPress configuration
define('DISALLOW_FILE_EDIT', true);
define('WP_DEBUG', false);

Key Management

  • Rotate encryption keys regularly.
  • Derive keys from WordPress salts.
  • Encrypt backups of sensitive configs.

Monitoring & Logging

  • Log all authentication attempts.
  • Monitor failed accesses for suspicious activity.
  • Track unusual API usage patterns.

Operational Security

Regular Updates

  • Keep the plugin, WordPress core, and PHP updated with security patches.

Access Control

  • Follow the principle of least privilege.
  • Enable two-factor authentication (2FA) for admins.
  • Conduct periodic security audits.

Network Security

  • Use a Web Application Firewall (WAF) for extra protection.
  • Enforce HTTPS with modern ciphers.
  • Implement security headers (e.g., CSP, HSTS).

Incident Response

Detection & Analysis

  1. Set up logging and monitoring systems.
  2. Configure alerts for suspicious activity.
  3. Classify incidents by severity.

Response Procedures

  1. Contain the incident by isolating systems.
  2. Preserve evidence (logs and data).
  3. Communicate with affected parties as needed.
  4. Recover from clean backups.

Post-Incident Activities

  1. Perform root cause analysis.
  2. Implement fixes and improvements.
  3. Document lessons learned.
  4. Update procedures and report for compliance.
