**Prerequisite**: Phases 1-3 complete (core features, enterprise features, integrations, performance optimization)  
**Deliverable**: Multilingual Press Zone v1.0.0 launched on WordPress.org and press.zone marketplace

---

## Week 13: Security Audit & Hardening

### Objectives

- Comprehensive security audit following OWASP Top 10
- Penetration testing
- Code review for vulnerabilities
- Security documentation

### Tasks

#### 13.1 Security Audit (Days 1-2)

**Tool Setup**:
- [ ] Install PHPCS with WordPress Coding Standards
- [ ] Install PHPStan for static analysis
- [ ] Set up WPCS security sniffs
- [ ] Configure Psalm for type safety

**Automated Scans**:
```bash
# PHPCS security scan
phpcs --standard=WordPress-Security includes/ multilingual-press-zone.php

# PHPStan analysis (level 8)
phpstan analyse -l 8 includes/ multilingual-press-zone.php

# Psalm scan
psalm --show-info=true
```

**Manual Review Checklist**:
- [ ] All database queries use `$wpdb->prepare()`
- [ ] All output escaped (`esc_html()`, `esc_attr()`, `esc_url()`)
- [ ] All input sanitized (`sanitize_text_field()`, `absint()`)
- [ ] Nonce verification on all forms and AJAX
- [ ] Capability checks (`current_user_can()`)
- [ ] No direct file access (check `ABSPATH` defined)
- [ ] No eval() or create_function()
- [ ] No SQL injection vulnerabilities
- [ ] No XSS vulnerabilities
- [ ] No CSRF vulnerabilities

#### 13.2 OWASP Top 10 Compliance (Days 3-4)

**Checklist**:

1. **A01: Broken Access Control**
   - [ ] All admin endpoints require `manage_options` capability
   - [ ] Translation endpoints check user permissions
   - [ ] License API validates site ownership

2. **A02: Cryptographic Failures**
   - [ ] License keys stored encrypted in database
   - [ ] API keys never exposed in JavaScript
   - [ ] HTTPS enforced for all api.press.zone calls

3. **A03: Injection**
   - [ ] All SQL queries parameterized via `$wpdb->prepare()`
   - [ ] No dynamic eval() or exec() calls
   - [ ] DOM manipulation uses `textContent`, not `innerHTML`

4. **A04: Insecure Design**
   - [ ] Rate limiting on license activation (10/minute)
   - [ ] Site limit enforcement
   - [ ] Translation approval workflow

5. **A05: Security Misconfiguration**
   - [ ] No debug mode in production
   - [ ] Error messages don't expose internals
   - [ ] File permissions correct (755 directories, 644 files)

6. **A06: Vulnerable Components**
   - [ ] All npm packages audited (`npm audit fix`)
   - [ ] No known WordPress core vulnerabilities
   - [ ] Third-party integrations reviewed

7. **A07: Authentication Failures**
   - [ ] WordPress nonces on all forms
   - [ ] Bearer token authentication for api.press.zone
   - [ ] No password storage (uses WordPress auth)

8. **A08: Software and Data Integrity**
   - [ ] Plugin signed for WordPress.org
   - [ ] Auto-updates verified via license system
   - [ ] No unsigned third-party code loaded

9. **A09: Logging Failures**
   - [ ] Critical actions logged (activation, deactivation)
   - [ ] Failed license validations logged
   - [ ] Error logs don't contain sensitive data

10. **A10: Server-Side Request Forgery**
    - [ ] All external API calls validated
    - [ ] No user-controlled URLs in `wp_remote_get()`
    - [ ] api.press.zone hostname hardcoded

#### 13.3 Penetration Testing (Day 5)

**Tools**:
- WPScan (WordPress vulnerability scanner)
- Burp Suite Community (web app scanner)
- OWASP ZAP (automated scanner)

**Test Scenarios**:
1. **SQL Injection**: Try injecting SQL in all input fields
2. **XSS**: Try injecting `<script>alert('xss')</script>` in all fields
3. **CSRF**: Try submitting forms without nonces
4. **Privilege Escalation**: Try accessing admin endpoints as subscriber
5. **File Upload**: Try uploading PHP files (if applicable)
6. **License Bypass**: Try activating without valid license

**Remediation**:
- [ ] Document all findings
- [ ] Assign severity (Critical, High, Medium, Low)
- [ ] Fix all Critical and High findings
- [ ] Create tickets for Medium/Low findings
