  }
};

Verification Methods

Multiple verification options:

const verificationMethods = {
  dns_txt: {
    name: 'DNS TXT Record',
    difficulty: 'Medium',
    time: '5-60 minutes',
    permanent: true,
    
    steps: [
      'Get verification code',
      'Add TXT record to DNS',
      'Wait for propagation',
      'Verify in system'
    ],
    
    example: {
      type: 'TXT',
      name: '_verification',
      value: 'leadconduit-verify=abc123xyz789'
    }
  },
  
  file_upload: {
    name: 'HTML File Upload',
    difficulty: 'Easy',
    time: '5 minutes',
    permanent: false,
    
    steps: [
      'Download verification file',
      'Upload to root directory',
      'Ensure public access',
      'Click verify'
    ],
    
    example: {
      filename: 'leadconduit-verify-abc123.html',
      location: 'https://example.com/leadconduit-verify-abc123.html',
      content: 'leadconduit-verification: abc123xyz789'
    }
  },
  
  meta_tag: {
    name: 'HTML Meta Tag',
    difficulty: 'Easy',
    time: '5 minutes',
    permanent: false,
    
    steps: [
      'Get meta tag code',
      'Add to homepage <head>',
      'Publish changes',
      'Verify'
    ],
    
    example: '<meta name="leadconduit-verification" content="abc123xyz789">'
  },
  
  cname: {
    name: 'CNAME Record',
    difficulty: 'Advanced',
    time: '5-60 minutes',
    permanent: true,
    
    steps: [
      'Create subdomain',
      'Add CNAME record',
      'Point to verification URL',
      'Verify ownership'
    ],
    
    example: {
      type: 'CNAME',
      name: 'verify.example.com',
      value: 'verify-abc123.leadconduit.com'
    }
  }
};

Verification Process

Step-by-step implementation:

class DomainVerification {
  async verifyDomain(domain, method) {
    // Generate verification token
    const token = await this.generateToken(domain);
    
    // Provide instructions
    const instructions = this.getInstructions(method, token);
    
    // Wait for user to implement
    console.log('Instructions:', instructions);
    
    // Attempt verification
    const maxAttempts = 10;
    const delayMs = 30000; // 30 seconds
    
    for (let i = 0; i < maxAttempts; i++) {
      const result = await this.checkVerification(domain, method, token);
      
      if (result.verified) {
        return this.completeVerification(domain, result);
      }
      
      console.log(`Attempt ${i + 1} failed: ${result.reason}`);
      
      if (i < maxAttempts - 1) {
        await this.sleep(delayMs);
      }
    }
    
    throw new Error('Verification timeout');
  }
  
  async checkVerification(domain, method, token) {
    switch (method) {
      case 'dns_txt':
        return this.checkDNSVerification(domain, token);
        
      case 'file_upload':
        return this.checkFileVerification(domain, token);
        
      case 'meta_tag':
        return this.checkMetaTagVerification(domain, token);
        
      case 'cname':
        return this.checkCNAMEVerification(domain, token);
    }
  }
  
  async checkDNSVerification(domain, token) {
    try {
      const records = await this.resolveTXT(domain);
      const verifyRecord = `leadconduit-verify=${token}`;
      
      const found = records.some(record => 
        record.includes(verifyRecord)
      );
      
      return {
        verified: found,
        reason: found ? 'Success' : 'TXT record not found',
        records: records
      };
    } catch (error) {
      return {
        verified: false,
        reason: `DNS lookup failed: ${error.message}`
      };
    }
  }
  
  async checkFileVerification(domain, token) {
    const url = `https://${domain}/leadconduit-verify-${token}.html`;
    
    try {
      const response = await fetch(url);
      const content = await response.text();
      
      const expected = `leadconduit-verification: ${token}`;
      const verified = content.includes(expected);
      
      return {
        verified,
        reason: verified ? 'Success' : 'Invalid file content',
        url,
        status: response.status
      };
    } catch (error) {
      return {
        verified: false,
        reason: `File fetch failed: ${error.message}`
      };
    }
  }
}

Subdomain Verification

Verify subdomains efficiently:

class SubdomainVerification {
  async verifyWithWildcard(rootDomain) {
    // Wildcard verification covers all subdomains
    const wildcardToken = await this.generateWildcardToken(rootDomain);
    
    const dnsRecord = {
      type: 'TXT',
      name: '_leadconduit',
      value: `v=leadconduit1; d=${rootDomain}; t=${wildcardToken}`
    };
    
    // Verify root
    const rootVerified = await this.verifyDomain(rootDomain, dnsRecord);
    
    if (rootVerified) {
      // All subdomains now verified
      await this.enableSubdomains(rootDomain, '*');
      
      return {
        domain: rootDomain,
        subdomains: 'all',
        verified: true,
        method: 'wildcard'
      };
    }
  }
  
  async verifySpecificSubdomains(rootDomain, subdomains) {
    const results = [];
    
    for (const subdomain of subdomains) {
      const fullDomain = `${subdomain}.${rootDomain}`;
      
      try {
        const result = await this.verifyDomain(fullDomain, 'dns_txt');
        results.push({
          subdomain: fullDomain,
          verified: true,
          method: result.method
        });
      } catch (error) {
        results.push({
          subdomain: fullDomain,
          verified: false,
          error: error.message
        });
      }
    }
    
    return results;
  }
}

📝 Form Whitelisting

Whitelist Configuration

Control which forms can submit:

class FormWhitelist {
  constructor() {
    this.whitelist = new Map();
    this.rules = [];
  }
  
  addForm(config) {
    const formEntry = {
      id: this.generateFormId(),
      
      // Form identification
      url: config.url,
      domain: new URL(config.url).hostname,
      path: new URL(config.url).pathname,
      
      // Whitelist settings
      status: 'active',
      added_date: new Date(),
      expires: config.expires || null,
      
      // Security settings
      require_https: config.require_https !== false,
      allowed_methods: config.methods || ['POST'],
      
      // Validation rules
      validation: {
        required_fields: config.required_fields || [],
        blocked_fields: config.blocked_fields || [],
        
        consent_required: config.consent_required !== false,
        consent_selector: config.consent_selector,
        
        captcha_required: config.captcha_required || false,
        captcha_type: config.captcha_type || 'recaptcha_v2'
      },
      
      // Rate limiting
      rate_limits: {
        per_minute: config.rate_limit_minute || 60,
        per_hour: config.rate_limit_hour || 1000,
        per_day: config.rate_limit_day || 10000
      },
      
      // Tracking
      metrics: {
        submissions: 0,
        accepted: 0,
        rejected: 0,
        last_submission: null
      }
    };
    
    this.whitelist.set(formEntry.id, formEntry);
    return formEntry;
  }
  
  validateSubmission(request) {
    const url = request.headers.referer || request.headers.origin;
    
    if (!url) {
      return {
        allowed: false,
        reason: 'No referer header'
      };
    }
    
    // Find matching form
    const form = this.findMatchingForm(url);
    
    if (!form) {
      return {
        allowed: false,
        reason: 'Form not whitelisted',
        url
      };
    }
    
    // Validate form status
    if (form.status !== 'active') {
      return {
        allowed: false,
        reason: `Form ${form.status}`,
        form_id: form.id
      };
    }
    
    // Check expiration
    if (form.expires && new Date() > form.expires) {
      return {
        allowed: false,
        reason: 'Form whitelist expired',
        expired: form.expires
      };
    }
    
    // Validate HTTPS requirement
    if (form.require_https && !url.startsWith('https://')) {
      return {
        allowed: false,
        reason: 'HTTPS required'
      };
    }
    
    // Check rate limits
    const rateLimitCheck = this.checkRateLimits(form, request);
    if (!rateLimitCheck.allowed) {
      return rateLimitCheck;
    }
    
    // Validate fields
    const fieldCheck = this.validateFields(form, request.body);
    if (!fieldCheck.valid) {
      return {
        allowed: false,
        reason: fieldCheck.reason,
        field: fieldCheck.field
      };
    }
    
    // Update metrics
    this.updateMetrics(form, 'submission');
    
    return {
      allowed: true,
      form_id: form.id,
      validations_passed: true
    };
  }
}

Dynamic Whitelisting

Auto-discover and whitelist forms:

class DynamicWhitelist {
  async scanDomainForForms(domain) {
    const forms = [];
    
    // Scan common pages
    const pagesToScan = [
      '/',
      '/contact',
      '/quote',
      '/get-started',
      '/free-quote',
      '/request-info'
    ];
    
    for (const page of pagesToScan) {
      try {
        const url = `https://${domain}${page}`;
        const pageContent = await this.fetchPage(url);
        const pageForms = this.extractForms(pageContent, url);
        
        forms.push(...pageForms);
      } catch (error) {
        console.log(`Failed to scan ${page}: ${error.message}`);
      }
    }
    
    // Analyze forms
    const analyzed = forms.map(form => this.analyzeForm(form));
    
    // Auto-whitelist safe forms
    const safeFormsforms = analyzed.filter(f => f.safety_score > 0.8);
    
    return {
      found: forms.length,
      analyzed: analyzed,
      auto_whitelisted: safeFormsforms.length,
      require_review: analyzed.filter(f => f.safety_score <= 0.8)
    };
  }
  
  analyzeForm(form) {
    const analysis = {
      url: form.url,
      method: form.method,
      fields: form.fields,
      
      safety_score: 1.0,
      issues: [],
      recommendations: []
    };
    
    // Check HTTPS
    if (!form.url.startsWith('https://')) {
      analysis.safety_score -= 0.3;
      analysis.issues.push('Not using HTTPS');
      analysis.recommendations.push('Enable SSL/TLS');
    }
    
    // Check consent
    const hasConsent = form.fields.some(f => 
      f.type === 'checkbox' && 
      (f.name.includes('consent') || f.name.includes('agree'))
    );
    
    if (!hasConsent) {
      analysis.safety_score -= 0.2;
      analysis.issues.push('No visible consent checkbox');
      analysis.recommendations.push('Add clear consent language');
    }
    
    // Check for sensitive fields
    const sensitiveFields = form.fields.filter(f => 
      f.name.match(/ssn|social|tax|account/i)
    );
    
    if (sensitiveFields.length > 0) {
      analysis.safety_score -= 0.4;
      analysis.issues.push('Contains sensitive fields');
      analysis.recommendations.push('Review data collection necessity');
    }
    
    return analysis;
  }
}

🔒 Data Security Measures

Field-Level Encryption

Protect sensitive data:

class FieldEncryption {
  constructor(config) {
    this.algorithm = config.algorithm || 'aes-256-gcm';
    this.keyManagement = new KeyManagement(config.keyStore);
  }
  
  async encryptField(fieldName, value, context) {
    // Determine if encryption needed
    if (!this.shouldEncrypt(fieldName, value)) {
      return { encrypted: false, value };
    }
    
    // Get encryption key
    const key = await this.keyManagement.getKey(context.tenant);
    
    // Encrypt value
    const encrypted = await this.encrypt(value, key);
    
    // Store metadata
    const metadata = {
      field: fieldName,
      algorithm: this.algorithm,
      key_id: key.id,
      encrypted_at: new Date(),
      context: {
        user: context.user,
        ip: context.ip,
        purpose: context.purpose
      }
    };
    
    return {
      encrypted: true,
      value: encrypted,
      metadata
    };
  }
  
  shouldEncrypt(fieldName, value) {
    // Always encrypt certain fields
    const alwaysEncrypt = ['ssn', 'tax_id', 'account_number', 'routing_number'];
    if (alwaysEncrypt.includes(fieldName)) return true;
    
    // Pattern-based encryption
    const patterns = [
      { pattern: /^\d{3}-\d{2}-\d{4}$/, type: 'ssn' },
      { pattern: /^\d{9}$/, type: 'ssn_no_dashes' },
      { pattern: /^\d{2}-\d{7}$/, type: 'ein' }
    ];
    
    for (const { pattern, type } of patterns) {
      if (pattern.test(value)) {
        console.log(`Detected ${type} pattern in ${fieldName}`);
        return true;
      }
    }
    
    return false;
  }
  
  async decryptField(encryptedData, context) {
    // Verify permissions
    if (!this.canDecrypt(context)) {
      throw new Error('Insufficient permissions to decrypt');
    }
    
    // Log access
    await this.logDecryptAccess({
      field: encryptedData.metadata.field,
      user: context.user,
      reason: context.reason,
      timestamp: new Date()
    });
    
    // Get decryption key
    const key = await this.keyManagement.getKey(
      encryptedData.metadata.key_id
    );
    
    // Decrypt
    return this.decrypt(encryptedData.value, key);
  }
}

Data Masking

Protect PII in logs and displays:

class DataMasking {
  constructor() {
    this.rules = this.loadMaskingRules();
  }
  
  maskObject(obj, context) {
    const masked = {};
    
    for (const [key, value] of Object.entries(obj)) {
      masked[key] = this.maskValue(key, value, context);
    }
    
    return masked;
  }
  
  maskValue(fieldName, value, context) {
    if (!value) return value;
    
    // Find applicable rule
    const rule = this.findRule(fieldName, value);
    
    if (!rule) return value;
    
    // Apply masking based on context
    const maskLevel = this.getMaskLevel(context);
    
    switch (maskLevel) {
      case 'full':
        return this.fullMask(value, rule);
        
      case 'partial':
        return this.partialMask(value, rule);
        
      case 'none':
        return value;
        
      default:
        return this.defaultMask(value, rule);
    }
  }
  
  partialMask(value, rule) {
    switch (rule.type) {
      case 'ssn':
        return value.replace(/^(\d{3})-?(\d{2})-?(\d{4})$/, 'XXX-XX-$3');
        
      case 'phone':
        return value.replace(/^(\d{3})(\d{3})(\d{4})$/, '($1) XXX-$3');
        
      case 'email':
        const [local, domain] = value.split('@');
        const maskedLocal = local[0] + '*'.repeat(local.length - 2) + local.slice(-1);
        return `${maskedLocal}@${domain}`;
        
      case 'credit_card':
        return value.replace(/^(\d{4})(\d+)(\d{4})$/, '$1-XXXX-XXXX-$3');
        
      default:
        return this.genericMask(value);
    }
  }
  
  getMaskLevel(context) {
    // Production always masks
    if (context.environment === 'production') {
      return context.user?.role === 'admin' ? 'partial' : 'full';
    }
    
    // Development environments
    if (context.environment === 'development') {
      return 'partial';
    }
    
    // Based on user role
    const roleMaskLevels = {
      'admin': 'partial',
      'support': 'partial',
      'viewer': 'full',
      'api': 'full'
    };
    
    return roleMaskLevels[context.user?.role] || 'full';
  }
}

👥 Access Control

Role-Based Access

Implement RBAC:

class AccessControl {
  constructor() {
    this.roles = new Map();
    this.permissions = new Map();
    this.setupDefaultRoles();
  }
  
  setupDefaultRoles() {
    // Admin role
    this.addRole('admin', {
      permissions: ['*'], // All permissions
      description: 'Full system access'
    });
    
    // Manager role
    this.addRole('manager', {
      permissions: [

        'leads:export',
        'reports:*',
        'users:read'
      ],
      description: 'Manage flows and view data'
    });
    
    // Operator role
    this.addRole('operator', {
      permissions: [
        'flows:read',
        'flows:write',
        'leads:read',
        'reports:read'
      ],
      description: 'Day-to-day operations'
    });
    
    // Viewer role
    this.addRole('viewer', {
      permissions: [
        'flows:read',
        'leads:read:masked',
        'reports:read'
      ],
      description: 'Read-only access'
    });
    
    // API role
    this.addRole('api', {
      permissions: [
        'leads:create',
        'leads:read:own',
        'webhooks:send'
      ],
      description: 'API access only'
    });
  }
  
  checkPermission(user, resource, action) {
    const permission = `${resource}:${action}`;
    
    // Get user's effective permissions
    const userPermissions = this.getUserPermissions(user);
    
    // Check exact match
    if (userPermissions.has(permission)) {
      return { allowed: true, matched: permission };
    }
    
    // Check wildcards
    if (userPermissions.has('*')) {

    }
    
    // Check special conditions
    const conditionalCheck = this.checkConditionalPermissions(
      user,
      resource,
      action
    );
    
    if (conditionalCheck.allowed) {
      return conditionalCheck;
    }
    
    return {
