Data Classification

Data Classification

Overview

Data classification is critical for security, compliance, and governance. This skill covers:

• Discovering and identifying sensitive data fields across ServiceNow
• Implementing data masking strategies for PII/PHI protection
• Automated PII/PHI discovery using patterns and heuristics
• Applying classification labels to tables and fields
• Compliance with GDPR, HIPAA, PCI-DSS, and other regulations

When to use:

• Initial security assessment of ServiceNow instance
• Preparing for compliance audits (GDPR, HIPAA, SOX, PCI-DSS)
• Implementing data privacy controls
• Setting up data masking for non-production environments
• Creating data governance policies

Prerequisites

• Roles: admin, security_admin, data_privacy_admin
• Access: sys_dictionary, sys_db_object, field-level metadata
• Plugins: Data Classification (optional), Encryption (for encryption at rest)
• Knowledge: Regulatory requirements (GDPR, HIPAA, PCI-DSS)

Phase 5: Compliance Reporting

5.1 Generate Classification Report

Create data classification inventory:

Tool: SN-Execute-Background-Script
Parameters:
  script: |
    var report = {
      generated: new GlideDateTime().toString(),
      summary: {
        total_tables: 0,
        classified_tables: 0,
        total_fields: 0,
        classified_fields: 0
      },
      by_level: {
        'Public': { tables: [], fields: [] },
        'Internal': { tables: [], fields: [] },
        'Confidential': { tables: [], fields: [] },
        'Restricted': { tables: [], fields: [] },
        'Secret': { tables: [], fields: [] }
      },
      unclassified: {
        sensitive_tables: [],
        sensitive_fields: []
      }
    };

    // Get table classifications
    var props = new GlideRecord('sys_properties');
    props.addQuery('name', 'STARTSWITH', 'data.classification.');
    props.query();

    while (props.next()) {
      var propName = props.name.toString();
      var classification = props.value.toString();
      var parts = propName.replace('data.classification.', '').split('.');

      if (parts.length === 1) {
        // Table classification
        report.summary.classified_tables++;
        if (report.by_level[classification]) {
          report.by_level[classification].tables.push(parts[0]);
        }
      } else if (parts.length === 2) {
        // Field classification
        report.summary.classified_fields++;
        if (report.by_level[classification]) {
          report.by_level[classification].fields.push(parts[0] + '.' + parts[1]);
        }
      }
    }

    // Count total tables
    var tables = new GlideAggregate('sys_db_object');
    tables.addAggregate('COUNT');
    tables.query();
    if (tables.next()) {
      report.summary.total_tables = parseInt(tables.getAggregate('COUNT'));
    }

    // Count total fields
    var fields = new GlideAggregate('sys_dictionary');
    fields.addNotNullQuery('element');
    fields.addAggregate('COUNT');
    fields.query();
    if (fields.next()) {
      report.summary.total_fields = parseInt(fields.getAggregate('COUNT'));
    }

    gs.info('DATA CLASSIFICATION REPORT:\n' + JSON.stringify(report, null, 2));

5.2 GDPR Data Map

Generate GDPR-compliant data map:

Tool: SN-Execute-Background-Script
Parameters:
  script: |
    var gdprMap = {
      generated: new GlideDateTime().toString(),
      data_controller: 'Your Organization Name',
      personal_data_inventory: [],
      lawful_basis: {},
      retention_periods: {},
      third_party_sharing: []
    };

    // Find all PII fields
    var piiFields = [
      { table: 'sys_user', fields: ['first_name', 'last_name', 'email', 'phone', 'mobile_phone', 'home_phone', 'location'] },
      { table: 'customer_contact', fields: ['first_name', 'last_name', 'email', 'phone', 'mobile_phone'] },
      { table: 'hr_core_profile', fields: ['first_name', 'last_name', 'date_of_birth', 'ssn', 'address', 'city', 'state', 'zip'] }
    ];

    for (var i = 0; i < piiFields.length; i++) {
      var tableInfo = piiFields[i];

      // Count records
      var gr = new GlideAggregate(tableInfo.table);
      gr.addAggregate('COUNT');
      gr.query();
      var recordCount = 0;
      if (gr.next()) {
        recordCount = parseInt(gr.getAggregate('COUNT'));
      }

      gdprMap.personal_data_inventory.push({
        table: tableInfo.table,
        fields: tableInfo.fields,
        record_count: recordCount,
        data_subjects: 'Employees/Customers',
        purpose: 'Business operations',
        lawful_basis: 'Legitimate interest / Contract performance'
      });
    }

    // Define retention periods
    gdprMap.retention_periods = {
      'sys_user': 'Duration of employment + 7 years',
      'customer_contact': 'Duration of relationship + 5 years',
      'incident': '3 years after closure',
      'hr_core_profile': 'Duration of employment + 7 years'
    };

    gs.info('GDPR DATA MAP:\n' + JSON.stringify(gdprMap, null, 2));

Tool Usage Summary

Best Practices

• Inventory First: Complete data discovery before implementing controls
• Risk-Based Approach: Prioritize highest-risk data (PII, PHI, PCI)
• Defense in Depth: Combine ACLs, encryption, masking, and auditing
• Regular Scans: Schedule periodic PII discovery scans
• Document Everything: Maintain data classification records for audits
• Non-Prod Masking: Always mask production data in non-prod environments
• Least Privilege: Only grant access to classified data when necessary

Troubleshooting

Data Masking Not Applied

Symptom: Users see unmasked data Cause: Display business rule not executing Solution: Check business rule order and conditions; verify role checks

PII Scan Missing Fields

Symptom: Known PII fields not detected Cause: Field naming doesn't match patterns Solution: Add custom patterns for organization-specific naming

Classification Not Persisting

Symptom: Classifications reset or missing Cause: Properties not created in correct scope Solution: Verify sys_properties scope and update set capture

Encryption Performance

Symptom: Slow queries on encrypted fields Cause: Encryption prevents index usage Solution: Only encrypt truly sensitive fields; use reference fields for lookups
