Hey there cybersecurity friends! 👋 As an experienced ISO 27001 consultant, I know first-hand how crucial yet confusing the Statement of Applicability (aka SoA) can be.

This mandatory document scopes your ISMS by identifying relevant controls from Annex A of the standard. Get it wrong, and your certification attempt is doomed from the start! 😱

But craft a rock-solid SoA, and it paves the way for ISO 27001 success. ✅

In this comprehensive guide, you’ll learn:

• 🤔 Exactly what an SoA is
• 🔍 How to select the right controls
• 📃 6 steps for putting together an SoA
• 💡 Tips for making your SoA shine
• 🚨 Common SoA mistakes to avoid

Let’s do this!

🤔 What is a Statement of Applicability?

The SoA lists all the ISO 27001 controls from Annex A that are applicable to your organisation.

For each control, you must justify whether it will be:

• 🛡️ Implemented
• 🚫 Excluded (with reasons)

Per [clause 6.1.3d] of the standard, the SoA should contain:

• ✅ Applicable controls from Annex A
• 👍 Justification for inclusion
• 👎 Justification for excluding controls
• 🗣️ Whether controls are implemented or not

This shows you’ve carefully analysed risks and chosen suitable controls. It demonstrates commitment from leadership to address security gaps.

In a nutshell, the SoA scopes your ISMS by translating Annex A into a set of prioritised, risk-based security controls for your unique organisation.

Auditors scrutinise your SoA closely, so it’s crucial to get it right!

🔎 How to Select the Right Controls

Choosing controls for your SoA involves:

🕵️ Analysing Context

First, thoroughly analyse your:

• 🏢 Business model, structure, locations
• 💻 Technologies and systems
• 📜 Compliance obligations
• 🔐 Security culture maturity

🧮 Conducting Risk Assessments

Then, conduct information security risk assessments across your business.

This identifies threats, vulnerabilities, probabilities, and impacts.

Prioritise addressing any unacceptable risks through appropriate controls.

📈 Aligning with Objectives

Select controls that align with your strategic business goals and security priorities.

Balance security with productivity – don’t over-control low risks.

🏷️ Considering Constraints

Factor in your budget, resources, and capabilities.

Leverage any existing security controls already implemented.

📃 6 Steps to Craft an Effective SoA

Follow these steps to develop an SoA that ticks all the boxes:

1. Gather Inputs

💡 Collect information to inform control selection:

• 🕵️ Risk assessment results
• 🌐 IT infrastructure and systems
• 📜 Compliance obligations

2. Select Controls

🔎 Thoroughly analyse Annex A and select relevant controls based on:

• 📈 Organisational context
• 🕵️ Risk assessments
• ⚖️ Legal and regulatory requirements

3. Document Decisions

📋 For each control, document:

• ✅ If relevant and will be implemented
• 🚫 If excluded, along with justification

4. Review and Revise

👥 Have stakeholders review your initial SoA draft.

📝 Revise based on their feedback to catch any gaps.

5. Finalise and Approve

📑 Finalise the SoA and obtain signed approval from leadership.

This demonstrates their commitment to implementing controls.

6. Communicate and Review

📧 Publish and communicate the approved SoA to relevant parties.

📅 Review it annually or when major security changes occur.

This process helps ensure your SoA is accurate, complete, and up-to-date.

💡 Tips for an Awesome SoA

Beyond just compliance, a well-crafted SoA showcases your security program.

👇 Here are some tips for making your SoA shine:

• 📋 Use a template – Adapt a pre-made SoA template to save time. Customise it for your organisation. You can check our ISO 27001 SoA template.
• 🖌️ Make it visual – Use colour, charts, icons, etc. Avoid dense walls of text.
• 🗂️ Organise logically – Group related controls together under intuitive sections and headings.
• 👤 Assign owners – Identify who’s responsible for implementing each control.
• 🔎 Show evidence – Reference documents or URLs evidencing implementation.
• 📝 Write clearly – Explain decisions simply using plain language.
• 📈 Track progress – Use a spreadsheet to track implementation progress over time.

With these creative approaches, your SoA will stand out and tell a compelling security story!

🚨 Common SoA Mistakes to Avoid

On the other hand, these common missteps can weaken your SoA:

• 🙈 Excluding controls without justification
• 🤷‍♂️ Including irrelevant controls to inflate the SoA
• ❓ Forgetting to assign control owners
• 🤐 Failing to properly communicate the SoA
• 🤦‍♂️ Neglecting periodic reviews to keep it current

Avoiding these pitfalls ensures your SoA remains robust through certification and beyond.

FAQ

Q: What is the purpose of the SoA?

Q: How detailed should the justifications be in my SoA?
A: The justifications should be detailed enough to demonstrate you have properly considered each control, but avoid excessive wordiness. Be concise yet thorough in explaining your reasoning.

Q: Can I just use all the Annex A controls in my SoA?
A: No, you should not include irrelevant controls just to inflate your SoA. It is important to customise it based on your organisation’s unique context and risk assessment results.
