## Technology-Specific Security Analysis

### Frontend Security (React/TypeScript)
```typescript
// Current Security Implementation Assessment
interface SecurityAssessment {
  xssProtection: {
    status: 'Implemented' | 'Partial' | 'Missing';
    details: string;
    recommendations: string[];
  };
  
  authenticationSecurity: {
    tokenStorage: 'Secure' | 'Insecure';
    sessionManagement: 'Implemented' | 'Missing';
    recommendations: string[];
  };
  
  dataProtection: {
    encryptionInTransit: boolean;
    sensitiveDataHandling: 'Secure' | 'Needs Improvement';
    recommendations: string[];
  };
}

// Example Security Improvements
const securityImprovements = {
  // XSS Prevention Enhancement
  implementCSP: `
    // Content Security Policy Configuration
    const cspConfig = {
      directives: {
        defaultSrc: ["'self'"],
        scriptSrc: ["'self'", "'unsafe-inline'"],
        styleSrc: ["'self'", "'unsafe-inline'"],
        imgSrc: ["'self'", "data:", "https:"],
        connectSrc: ["'self'", "https://api.example.com"]

    ];
    
    const handleValidationErrors = (req, res, next) => {

      if (!errors.isEmpty()) {
        return res.status(400).json({ errors: errors.array() });
      }
      next();

    // Rate limiting
    const limiter = rateLimit({
      windowMs: 15 * 60 * 1000, // 15 minutes
      max: 100, // limit each IP to 100 requests per windowMs

```

### Database Security
```sql
-- Database Security Assessment
-- Current Security Configuration Review
SELECT 
  @@version as database_version,
  @@sql_mode as sql_mode,
  @@local_infile as local_infile_status,
  @@secure_file_priv as secure_file_privileges;

-- User Access Review
SELECT 
  user,
  host,
  authentication_string,
  password_expired,
  account_locked,
  password_lifetime
FROM mysql.user;

-- Privilege Audit
SHOW GRANTS FOR 'app_user'@'localhost';

-- Security Recommendations Implementation
-- 1. Create dedicated application user with minimal privileges
CREATE USER 'app_readonly'@'localhost' IDENTIFIED BY 'strong_password_here';
GRANT SELECT ON application_db.* TO 'app_readonly'@'localhost';

CREATE USER 'app_readwrite'@'localhost' IDENTIFIED BY 'strong_password_here';
GRANT SELECT, INSERT, UPDATE ON application_db.* TO 'app_readwrite'@'localhost';

-- 2. Enable SSL/TLS encryption
ALTER USER 'app_user'@'localhost' REQUIRE SSL;

-- 3. Implement audit logging
INSTALL PLUGIN audit_log SONAME 'audit_log.so';
SET GLOBAL audit_log_policy = ALL;
SET GLOBAL audit_log_format = JSON;
```

## Security Implementation Guidelines

### Secure Coding Standards
1. **Input Validation**
   - Validate all user inputs on both client and server side
   - Use whitelist validation approach
   - Implement proper error handling without information disclosure

2. **Authentication & Authorization**
   - Implement multi-factor authentication where possible
   - Use secure session management practices
   - Implement proper role-based access control

3. **Data Protection**
   - Encrypt sensitive data at rest and in transit
   - Implement proper key management practices
   - Use secure communication protocols (HTTPS, TLS 1.3)

### Security Testing Strategy
1. **Static Application Security Testing (SAST)**
   - Integrate security scanning in CI/CD pipeline
   - Use tools like SonarQube, Checkmarx, or Semgrep
   - Regular dependency vulnerability scanning

2. **Dynamic Application Security Testing (DAST)**
   - Automated penetration testing
   - API security testing
   - Runtime security monitoring

3. **Interactive Application Security Testing (IAST)**
   - Real-time vulnerability detection
   - Runtime application self-protection (RASP)
   - Continuous security monitoring
