ISO 27001 Clause 6.1.3 Information security risk treatment

What is Clause 6.1.3?

Clause 6.1.3 of ISO 27001 focuses on Information Security Risk Treatment. It outlines the process of selecting appropriate treatment options—such as mitigating, transferring, avoiding, or accepting risks—and determining necessary controls to address them.

Clause 6.1.3 – Turning Risk Insights into Action

When it comes to information security, identifying risks is only half the battle. Clause 6.1.3 Information Security Risk Treatment is where the action happens. It’s about taking the risks you’ve identified in Clause 6.1.2 and deciding how to address them effectively. This step ensures that your ISMS doesn’t just recognize threats but actively protects your organization from them.

Why Clause 6.1.3

Risk treatment is the bridge between awareness and action. Without it, all the effort put into assessing risks would be wasted. Think about it: You’ve identified potential vulnerabilities, but what’s the point if they’re not managed or mitigated? Clause 6.1.3 ensures that risks don’t just sit on a spreadsheet—they’re tackled head-on.

It ensures risks are addressed in a way that aligns with your organization’s goals and resources.
It forces you to consider multiple approaches to risk management, from mitigation to acceptance.
It establishes accountability by documenting decisions and assigning responsibilities.

A Quick Overview of the Process

Clause 6.1.3 breaks risk treatment into clear steps:

Select Treatment Options: Decide whether to avoid, transfer, mitigate, or accept each risk.
Identify Necessary Controls: Determine what actions or measures are required to manage those risks.
Compare with Annex A: Verify that no critical controls are overlooked using Annex A as a reference.
Document Decisions in the SoA: Create a Statement of Applicability (SoA) to explain which controls are included, which are excluded, and why.
Develop a Risk Treatment Plan: Define actionable steps, timelines, and responsibilities to implement the chosen treatments.

Why Documentation is Key

Documentation isn’t just a checkbox for compliance—it’s how you ensure clarity and accountability. Whether it’s the SoA or your risk treatment plan, maintaining accurate records is critical for:

Audits: ISO 27001 auditors will closely review your treatment process.
Consistency: Clear documentation ensures actions are repeatable across teams.
Stakeholder Trust: A well-documented process demonstrates that risks are being managed systematically.

Selecting Appropriate Risk Treatment Options – Navigating the Four Paths

Now that we’ve set the stage, it’s time to tackle the first critical step of Clause 6.1.3: selecting the right treatment options for each risk. This is where you decide how to manage the risks you’ve identified, based on your organization’s specific needs, priorities, and resources.

Understanding the Four Risk Treatment Options

ISO 27001 provides four primary ways to address risks. Let’s break them down with real-world examples:

Risk Treatment Option	Description	Example
Avoid	Eliminating the activity or condition that creates the risk.	If using outdated software creates a high risk of data breaches, stop using it entirely by upgrading to a secure alternative.
Mitigate	Reducing the likelihood or impact of the risk through controls or measures.	To mitigate unauthorized access risks, implement multi-factor authentication (MFA) and stricter password policies.
Transfer	Shifting the responsibility for the risk to a third party, such as an insurer or service provider.	Transfer the risk of hardware failure by using a cloud service provider with high availability and disaster recovery capabilities.
Accept	Acknowledging the risk but taking no additional action, often because it is within acceptable levels or too costly to mitigate.	If the likelihood of a minor system outage is extremely low, and the financial impact is minimal, it may be acceptable to leave it untreated.

How to Choose the Right Option

Choosing the best treatment option isn’t just about the risk itself—it’s about balancing your organization’s risk tolerance, operational needs, and available resources.

Key Factors to Consider:

Risk Level: Use the results from your risk assessment to prioritize which risks require immediate treatment.
Cost-Benefit Analysis: Evaluate whether the cost of mitigating a risk is justified by the potential impact of the risk.
Stakeholder Expectations: Consider how customers, regulators, or partners view the risk. For example, accepting a risk might not sit well with clients demanding strict data security.
Operational Impact: Avoid introducing controls that disrupt business-critical processes unless absolutely necessary.

Making the Decision Collaborative

Risk treatment decisions should never happen in isolation. Involve stakeholders like IT managers, compliance officers, and even external experts if necessary. This ensures that decisions are informed, practical, and aligned with your organization’s goals.

Example Workflow:

Present the risk and its severity to stakeholders.
Propose the most viable treatment options, considering impact, likelihood, and cost.
Discuss and document the agreed-upon approach.

Common Pitfalls to Avoid

Treating Every Risk the Same Way: Not all risks require action. Focus your resources on high-priority risks first.
Overlooking Transfer Options: Many organizations forget that insurance or outsourcing can be a cost-effective way to handle certain risks.
Failing to Document Decisions: Always document why a specific treatment option was chosen, as this will be critical for audits and accountability.

What Are Controls in ISO 27001?

Controls are the tools, processes, or measures you put in place to reduce, transfer, avoid, or accept risks. These can range from technical solutions like firewalls to procedural actions like employee training. The key is to ensure that your controls align with the treatment options selected and are tailored to your organization’s needs.

Types of Controls:

Technical Controls: Encryption, access controls, firewalls.
Administrative Controls: Policies, training, and incident response plans.
Physical Controls: Secure facility access, CCTV, and environmental protections.

While these types of controls focus on the nature of the security measures, Annex A introduces controls categorized by their functionality:

Preventive Controls: Stop threats before they occur (e.g., firewalls, access restrictions).
Detective Controls: Identify and alert on security incidents (e.g., intrusion detection systems, activity logging).
Corrective Controls: Address and mitigate incidents after they occur (e.g., backups, disaster recovery plans).

The key difference is that Annex A’s categories focus on what the controls are designed to achieve, whereas the broader ISO 27001 classifications relate to how and where the controls are applied.

Steps to Identify Necessary Controls

1. Map Controls to Treatment Options

For each risk and its chosen treatment, determine the control(s) that will effectively address it.

Example:

Risk: Unauthorized access to customer data.
Treatment Option: Mitigate the risk.
Control: Implement multi-factor authentication (MFA) and role-based access controls (RBAC).

2. Use Established Frameworks

ISO 27001 Annex A provides a comprehensive list of information security controls, categorized by functionality (preventive, detective, corrective). Use it as a starting point to identify relevant controls.

Example from Annex A: Control 8.5: Secure authentication procedures.

3. Design Custom Controls (When Needed)

If Annex A doesn’t fully address a specific risk, you can design custom controls tailored to your organization’s unique needs.

Example: A custom application monitoring tool for detecting unusual activity in a proprietary system.

Balancing Flexibility and Compliance

While ISO 27001 encourages flexibility in designing controls, it also requires you to ensure no critical controls are missed. Use Annex A as a checklist to:

Verify that your identified controls cover all necessary areas.
Ensure all functional types—preventive, detective, and corrective—are appropriately addressed.
Justify any deviations, exclusions, or customizations.

Documenting Identified Controls

Every control you implement should be documented in the Statement of Applicability (SoA). This ensures transparency and accountability during audits. Your SoA should include:

A list of necessary controls.
Justifications for their inclusion.
Implementation status (e.g., planned, in progress, completed).
Justifications for excluding any Annex A controls.

Tip: Streamline with Templates

To simplify this process, use our ISO 27001:2022 SoA Template. It helps you with justifying the controls, ensuring alignment with ISO 27001 requirements while saving time on documentation.

Validating Against Annex A Controls – Completeness and Compliance

Once you’ve identified the controls needed to address your chosen risk treatment options, the next step is to validate them against Annex A of ISO 27001. This process ensures that no critical controls are missed and that your risk treatment measures are comprehensive and aligned with the standard.

Why Validation is Important

Validating your identified controls against Annex A serves two purposes:

Ensures Completeness: It acts as a checklist to verify that no critical areas have been overlooked.
Supports Compliance: Demonstrates to auditors that your ISMS aligns with ISO 27001’s requirements.

Steps to Validate Controls Against Annex A Controls

1. Compare Controls

Go through Annex A and match your identified controls to its categories. Ensure that each relevant control is either:

Included: If it addresses a risk or supports a treatment option.
Excluded: If it’s not applicable, with a clear justification documented.

Example:

Identified Control: Multi-factor authentication (MFA).
Annex A Match: Control 8.5 – Secure log-on procedures.
Action: Include MFA and document it in your Statement of Applicability (SoA).

2. Check for Gaps

Look for any controls in Annex A that might apply to your organization’s risks but were not initially identified. These could highlight areas where additional measures are needed.

To streamline this process, consider using our ISO 27001 GAP Analysis Template. This tool helps you systematically check Annex A controls, making it easier to spot missing or incomplete measures. It’s especially useful for identifying areas where additional actions are necessary to align with ISO 27001.

Example:

Annex A Control: Control 5.25 – Assessment of and decision on information security events.
Action: Implement an incident response procedure if no such control was identified during initial risk treatment planning.

3. Justify Exclusions

Not all Annex A controls will apply to your organization. For any excluded controls, provide a clear justification. This is critical for auditors to understand your reasoning.

Example:

Excluded Control: Control 8.22 – Segregation in networks.
Justification: The organization operates a single-network environment where segregation is not applicable.

Documenting Validation in the Statement of Applicability

The Statement of Applicability (SoA) is where you formally document the results of your validation process. This document includes:

A list of controls from Annex A that are applicable to your ISMS.
Justifications for why each control was included or excluded.
The implementation status of each control.

The SoA serves as a critical piece of evidence during audits, showing that you’ve thoroughly validated and documented your control choices.

Understanding Annex A’s Flexibility

While Annex A is an excellent starting point, remember that it’s not exhaustive. You can design and implement additional controls to address risks that Annex A doesn’t cover. For instance:

Custom logging and monitoring tools for proprietary systems.
Specialized training programs for unique operational contexts.

Tip: Simplify Validation with Templates

Use a ISO 27001:2022 SoA Template to streamline the process. It provides a structured format to document each control, its relevance, and implementation status, ensuring nothing is overlooked.

Producing the Statement of Applicability (SoA) – The Core Document of ISO 27001

The Statement of Applicability (SoA) is one of the most critical documents in ISO 27001. It’s a comprehensive record that outlines the controls your organization has chosen to implement, their current status, and why they were included or excluded. The SoA is a reflection of your risk management strategy and your organization’s commitment to information security.

What is the Statement of Applicability?

The SoA serves as a summary of your information security controls. It documents:

The controls selected from Annex A to address risks.
Justifications for including or excluding each control.
The implementation status of each control (e.g., planned, in progress, or implemented).

Think of the SoA as your organization’s roadmap for risk treatment, showing auditors and stakeholders how your ISMS aligns with ISO 27001 requirements.

Steps to Produce the SoA

1. List Necessary Controls

Start by listing all controls you’ve identified as necessary during the risk treatment process. Include controls selected from Annex A and any custom controls designed for your specific needs.

Example:

Control 8.5 (Secure Authentication): Secure authentication.
Custom Control: Proprietary monitoring tool for detecting anomalies in a specialized application.

2. Provide Justifications for Each Control

For every control, explain why it was included. This justification should tie back to the risks identified in Clause 6.1.2 Risk Assessment and the treatment options selected in Clause 6.1.3 Risk Treatment.

Example:

Control 8.24 (Use of Cryptograhy): Included to protect sensitive customer data during transmission and storage, mitigating the risk of unauthorized access.

3. Indicate Implementation Status

For each control, specify its current status:

Planned: The control has been selected but is not yet in place.
In Progress: Implementation is underway.
Implemented: The control is fully operational and effective.

This transparency helps auditors understand where your organization stands in terms of control implementation.

Example:

Control 8.2 (Privileged Access Rights): Status: Implemented.

4. Justify Exclusions

Not all Annex A controls will apply to your organization. For each excluded control, provide a clear justification. This is essential to demonstrate that exclusions are intentional and well-reasoned.

Example:

Excluded Control 7.6 (Working in Secure Areas): Justification: The organization operates in a virtual environment with no physical secure areas, making this control irrelevant.

Using Tools to Simplify SoA Creation

Creating an SoA can be time-intensive, but using a structured ISO 27001 Statement of Applicability Template can save time and ensure accuracy. This template helps you systematically document controls, justifications, and statuses, streamlining the process and ensuring compliance.

Creating the Risk Treatment Plan – Turning Strategy into Action

The Risk Treatment Plan is where your risk management strategy becomes actionable. It outlines the specific steps, responsibilities, and resources required to implement the controls you’ve identified and documented in the Statement of Applicability (SoA). This plan ensures that your risk treatment measures are practical, prioritized, and aligned with your organization’s operations.

What is a Risk Treatment Plan?

A Risk Treatment Plan (RTP) is a formal document that details how your organization will address the risks identified in your ISO 27001 risk assessment. It bridges the gap between selecting controls and implementing them effectively. A well-crafted RTP is not only essential for ISO 27001 compliance but also ensures that your ISMS remains practical and actionable.

Key Components of a Risk Treatment Plan

Defined Actions
Specify the exact steps needed to implement each control. These actions should directly address the risks identified in Clause 6.1.2.
- Example: For a risk of unauthorized system access, the action might be “Implement multi-factor authentication (MFA) for all users.”
Assigned Responsibilities
Clearly define who is responsible for executing each action. Assigning ownership ensures accountability and keeps the plan on track.
- Example: “The IT Security Team will configure and deploy MFA across all systems.”
Timelines and Milestones
Establish realistic deadlines for each action, including milestones to track progress.
- Example: “MFA implementation will be completed by Q3, with testing finalized by October 15th.”
Required Resources
Identify the tools, budget, and personnel needed to implement the plan. This helps ensure that all necessary resources are in place to support the actions.
- Example: “Allocate €10,000 for MFA software licenses and assign two IT staff for deployment.”

Steps to Develop the Risk Treatment Plan

1. Link Actions to Risks

Each action in the RTP should correspond to a specific risk and the selected treatment option. This ensures that all risks are systematically addressed.

Example:

Risk: Unauthorized database access.
Treatment Option: Mitigate the risk.
Action: Deploy a database firewall and implement role-based access control (RBAC).

2. Align with ISMS Processes

Your Risk Treatment Plan should integrate seamlessly into your organization’s existing ISMS processes. This ensures that actions are not performed in isolation but contribute to the overall effectiveness of your ISMS.

Example:

Include risk treatment actions in the internal audit schedule.
Align actions with existing incident response and change management processes.

3. Monitor and Adjust

Treat the RTP as a living document. Regularly monitor progress, update actions as needed, and ensure that controls are effective. Conduct periodic reviews to evaluate whether the plan aligns with changing business needs or regulatory requirements.

Tip: Use the ISO 27001 Risk Treatment Plan Template to document and track actions, responsibilities, and timelines. This structured approach simplifies compliance and ensures nothing is overlooked.

Ensuring Stakeholder Buy-In

Securing stakeholder approval is critical for the success of your RTP. Present the plan to risk owners, management, and relevant teams to:

Confirm responsibilities and timelines.
Ensure the plan aligns with organizational goals.
Gain acceptance of any residual risks that remain after treatment.

Approval and Acceptance – Finalizing the Risk Treatment Plan

Once the Risk Treatment Plan (RTP) is created, the next crucial step is obtaining approval from key stakeholders. This ensures that the plan is actionable, aligned with organizational goals, and that residual risks are formally accepted. Clause 6.1.3 emphasizes the importance of securing both risk owners’ approval and acceptance of residual risks as part of the risk management process.

Why Approval and Acceptance

Without formal approval, even the best-laid plans risk being delayed or ignored. Securing sign-off ensures:

Accountability: Risk owners take responsibility for implementing and monitoring controls.
Clarity: Everyone understands the agreed-upon actions and their rationale.
Alignment: The plan aligns with organizational objectives and stakeholder expectations.
Compliance: Demonstrates adherence to ISO 27001 requirements for risk management.

Steps to Obtain Approval and Acceptance

1. Present the Risk Treatment Plan

Organize a review meeting with relevant stakeholders, including risk owners, department heads, and senior management. Present the plan clearly, emphasizing:

The risks addressed.
The selected treatment options (avoid, mitigate, transfer, or accept).
The controls to be implemented.
Any residual risks that will remain after treatment.

Tip: Use visual aids like tables or dashboards to make the plan easier to digest. For example:

Risk	Treatment Option	Control	Residual Risk
Unauthorized database access	Mitigate	Multi-factor authentication	Minimal likelihood of brute force attacks

2. Gain Risk Owners’ Approval

Risk owners are individuals or teams responsible for specific risks and controls. Their approval signifies that they:

Understand their role in implementing and monitoring controls.
Agree to the timelines, responsibilities, and resources outlined in the plan.

Tip: Use a standardized approval form or workflow system to document approvals formally, ensuring clarity and traceability.

3. Obtain Acceptance of Residual Risks

Not all risks can be fully eliminated. Residual risks are those that remain after controls are implemented. These risks must be formally acknowledged and accepted by appropriate stakeholders, such as senior management or risk committees.

Key Considerations:

Ensure residual risks fall within the organization’s defined risk acceptance criteria.
Provide clear documentation showing why the residual risks are considered acceptable.

Example:

Residual Risk: A slight chance of phishing attacks bypassing email filters despite additional training and tools.
Reason for Acceptance: The risk is low, and the impact is manageable.

4. Document the Approval and Acceptance

Create a record of all approvals and accepted residual risks. This documentation is critical for:

Audits: ISO 27001 auditors will review the approvals as part of compliance checks.
Accountability: Ensures stakeholders understand their roles and decisions.

Maintaining Records of the Risk Treatment Process – Ensuring Compliance and Transparency

Completing the risk treatment process under Clause 6.1.3 requires meticulous record-keeping. ISO 27001 mandates that all steps, decisions, and actions are documented thoroughly to demonstrate compliance and provide a foundation for continuous improvement. Aligning your documentation with ISO 31000 principles further strengthens the integrity of your risk management process.

Why Maintaining Records is Essential

Proper documentation serves several critical purposes:

Compliance: Provides evidence that the organization meets ISO 27001 requirements.
Accountability: Ensures clear ownership and responsibility for actions.
Transparency: Builds trust with auditors, stakeholders, and regulators.
Improvement: Offers a historical record for refining the risk management process over time.

Key Documents to Maintain

1. Risk Register

The risk register is a comprehensive log of all identified risks, including:

Description of each risk.
Risk owner.
Risk levels (impact, likelihood, overall priority).
Treatment option selected (avoid, mitigate, transfer, accept).
Status (open, in progress, treated).

2. Risk Treatment Plan

This document outlines the actions, responsibilities, and timelines for implementing controls. It also includes details about required resources and links actions back to the specific risks they address.

3. Statement of Applicability (SoA)

The SoA provides a summary of all controls, their implementation status, and justifications for inclusion or exclusion. This is one of the most critical documents for ISO 27001 compliance.

4. Residual Risk Documentation

Records of residual risks, including their acceptance by stakeholders, and the rationale for why they fall within the organization’s risk tolerance.

5. Monitoring and Review Records

Logs and reports from periodic reviews, audits, or performance monitoring of controls. These records help track the effectiveness of risk treatment over time.

Aligning with ISO 31000 Principles

ISO 31000 provides guidelines for effective risk management. Aligning your documentation with these principles ensures that your risk treatment process is robust, consistent, and scalable.

Key ISO 31000 Principles to Incorporate:

Structured and Comprehensive: Ensure documentation is consistent and covers all stages of the risk treatment process.
Customizable: Tailor your documentation to fit your organization’s specific needs and risks.
Inclusive: Engage stakeholders and reflect their input in the records.
Dynamic: Keep records updated to reflect changes in risks, controls, or organizational objectives.

Tips for Effective Record-Keeping

Centralized Storage: Use a secure, centralized system to store and manage all risk treatment documentation.
Version Control: Maintain version histories to track updates and changes.
Templates and Tools: Use pre-designed templates like our ISO 27001 Risk Treatment Plan Template to streamline record creation and ensure consistency.
Audit Readiness: Regularly review records to ensure they meet the expectations of ISO 27001 audits.
