Gap Analysis Process

A thorough gap analysis identifies the difference between your current state and ISO 27018 requirements. This lesson guides you through conducting an effective gap analysis.

Gap Analysis Overview

Purpose: Identify gaps between current practices and ISO 27018 requirements

Benefits:

  • Understand scope of work required
  • Prioritize remediation efforts
  • Estimate costs and timeline
  • Create roadmap to certification
  • Identify quick wins

Gap Analysis Methodology

Phase 1: Current State Assessment

Step 1: Document Current Practices

  • Inventory existing policies and procedures
  • Review current security controls
  • Map data flows and processing activities
  • Identify current certifications (ISO 27001, SOC 2, etc.)
  • Interview key personnel

Step 2: Gather Evidence

  • Technical documentation
  • Security configurations
  • Audit logs
  • Training records
  • Incident reports
  • Contracts and agreements

Phase 2: Requirements Mapping

Step 1: Review ISO 27018 Controls Create checklist of all requirements:

  • Section 6: Privacy principles
  • Section 7: PII controller/processor obligations
  • Section 8: Additional ISO 27002 controls
  • Section 9: Guidance for public cloud PII processors

Step 2: Map to Current Controls For each requirement, identify:

  • Existing control (if any)
  • Implementation status
  • Evidence available
  • Gaps identified

Phase 3: Gap Identification

For Each Control, Determine:

Fully Compliant:

  • Control implemented completely
  • Evidence available
  • Meets all requirements
  • No action needed

Partially Compliant:

  • Control exists but incomplete
  • Some evidence available
  • Remediation needed
  • Quick fix possible

Not Compliant:

  • No control in place
  • No evidence
  • Significant work required
  • Major implementation needed

Not Applicable:

  • Control doesn't apply to your environment
  • Justification documented

Gap Remediation Planning

For Each Gap, Define:

1. Gap Description Clear statement of the gap

2. Control Requirement What the standard requires

3. Current State What exists today

4. Desired State What needs to exist

5. Remediation Steps Specific actions required

6. Resources Needed People, tools, budget

7. Timeline Start and completion dates

8. Owner Person accountable

9. Dependencies What must happen first

10. Success Criteria How to know it's done

11. Verification Method How to prove compliance

Quick Win Opportunities

Look for:

1. Documentation Gaps

  • Often quick to create
  • High compliance impact
  • Low cost

Examples:

  • Privacy policy updates
  • Procedure documentation
  • Form templates

2. Process Formalization

  • Activities already happening
  • Just need documentation
  • Minimal behavioral change

Examples:

  • Document existing training
  • Formalize incident response
  • Record management reviews

3. Configuration Changes

  • Technical controls exist
  • Just need proper configuration
  • Can be implemented quickly

Examples:

  • Enable existing encryption
  • Configure audit logging
  • Adjust access controls

Common Pitfalls

❌ Incomplete Assessment

  • Skipping technical verification
