Step 1: Understand Scope Requirements (15 minutes)

ISO 27001 Scope Requirements

ISO 27001 requires you to define:

Organizational Scope: Which parts of your organization are included System Scope: Which systems, processes, and data are included Geographic Scope: Which locations are included Temporal Scope: The time period for implementation

SOC 2 Scope Requirements

- [ ] Employee home offices (personal equipment)

**Rationale**: [Explain geographic boundaries]

Action: Complete your geographic scope mapping.

Step 4: Document Your Scope Statement (30 minutes)

Create Scope Statement

Write a clear, concise scope statement:

# Scope Statement Template

**Organization**: [Your Company Name]

**Scope**: The [ISO 27001 ISMS / SOC 2 System] covers [specific systems, processes, and data] that support [business function] for [customer types].

**In Scope**:

**Out of Scope**:

- [List excluded systems and processes]
- [List excluded organizational units]
- [List excluded data types]

**Rationale**: [Explain the business justification for scope boundaries]

**Effective Date**: [Date]
**Review Date**: [Date - typically annual]

Action: Draft your scope statement.

Step 5: Validate with Stakeholders (15 minutes)

Review with Key Stakeholders

Present your scope to:

  • Leadership: Ensure business alignment
  • IT Team: Verify technical accuracy
  • Legal Team: Confirm regulatory compliance
  • Audit Team: Validate audit readiness

Document Feedback

Record stakeholder input:

# Stakeholder Review Template

**Stakeholder**: [Name/Role]
**Feedback**: [Specific comments]
**Action Required**: [Changes needed]
**Status**: [Open/Closed]

Action: Conduct stakeholder review and document feedback.

Common Scope Definition Mistakes

Too Broad Scope

Problem: Including everything makes compliance unmanageable Solution: Focus on customer-facing systems and critical data

Too Narrow Scope

Problem: Excluding important systems creates gaps Solution: Include all systems that process customer data

Unclear Boundaries

Problem: Vague scope statements create audit issues Solution: Be specific about what's in and out of scope

Missing Rationale

Problem: No justification for scope decisions Solution: Document business reasons for scope boundaries

Scope Examples

Example 1: SaaS Company

Scope: Customer-facing web application and supporting infrastructure In Scope: Web app, database, payment processing, customer support tools Out of Scope: Internal HR systems, marketing tools, development environments

Example 2: Financial Services

Scope: Core banking systems and customer data processing In Scope: Core banking platform, customer portal, payment systems Out of Scope: Employee benefits systems, marketing databases

Example 3: Healthcare Provider

Scope: Patient care systems and protected health information In Scope: EMR system, patient portal, billing systems Out of Scope: Administrative systems, research databases

Next Steps

Once you have defined your scope:

  1. Get approval: Secure leadership sign-off on scope
  2. Document controls: Map controls to your scope
  3. Implement monitoring: Set up scope monitoring processes
  4. Plan reviews: Schedule regular scope reviews

Troubleshooting

"Our scope keeps changing"

  • Document scope change process
  • Require formal approval for changes
  • Update scope statement regularly

"Auditors question our scope"

  • Ensure scope aligns with business objectives
  • Document clear rationale for boundaries
  • Be prepared to defend scope decisions

"Scope is too complex"

  • Simplify by focusing on customer data
  • Start with core systems only
  • Expand scope gradually over time
