How to Integrate Your Statement of Applicability with Your Risk Assessment

The integration of your Statement of Applicability (SoA) with your risk assessment is a pivotal process in implementing an effective Information Security Management System (ISMS) compliant with ISO 27001. This integration ensures that the controls selected within the SoA are directly aligned with and appropriate for the risks identified by the risk assessment.

To integrate your own SoA with your risk assessment, first take a look at the comprehensive step-by-step guide below.

The SoA and the risk assessment are interconnected components of an ISMS. While the risk assessment identifies and evaluates risks based on their likelihood and impact, the SoA details which controls from ISO 27001 are applied to mitigate these risks. The effectiveness of an ISMS heavily relies on how well these two elements are synchronised.

Begin by identifying potential security threats and vulnerabilities that your organisation faces. Evaluate these risks considering the potential impact on your organisation and the likelihood of their occurrence. This assessment forms the foundation for all decisions regarding the selection and implementation of security controls.

Once risks are identified and prioritised, the next step is to map appropriate controls from ISO 27001 to these risks. Each control selected should be aimed at mitigating specific risks. This mapping should be explicitly documented, showing how each control addresses a particular threat or vulnerability.

In the SoA, provide a clear justification for each control that is included or excluded based on the risk assessment findings. This justification should detail the rationale behind the decision, focusing on how the control's implementation will mitigate the identified risks.

For each control implemented, document how it mitigates the identified risks. Include specific examples or scenarios that demonstrate the control’s effectiveness in reducing the risk to an acceptable level. This documentation will be invaluable during audits to show that your security measures are both appropriate and effective.

Both the risk assessment and the SoA should not be treated as static documents; they require regular reviews and updates. As new threats emerge, as the organisation's risk profile changes, or as external requirements evolve, both the risk assessment and the SoA should be updated to reflect these changes.

Throughout the process, engage with key stakeholders, including department heads, IT staff, and senior management. Their input can provide insights into potential risks and the practicality of implementing specific controls, ensuring broader acceptance and more effective security management.

Integrating the Statement of Applicability with risk assessment is critical for the success of an ISMS. This process ensures that every control implemented is backed by a clear, documented rationale that aligns with the organisation’s specific risk context.
