ISO 27001 Clause 6.1.3 focuses on "Information Security Risk Treatment" and requires organizations to implement and manage the risk treatment plan developed during the risk assessment process (Clause 6.1.2).
The key requirements of this clause are:
1. Risk Treatment Plan Implementation: Implement the approved risk treatment plan, which outlines the action plans and controls required to address the identified information security risks.
2. Determination of Controls: Determine the appropriate information security controls to be implemented based on the risk treatment options chosen in the risk treatment plan. These controls can be new or existing ones that need to be modified.
3. Control Implementation Plan: Develop and implement a plan for implementing the selected controls, including responsibilities, resource allocation, and timelines.
4. Residual Risk Acceptance: For any residual risks that cannot be mitigated or transferred, obtain formal approval from relevant stakeholders to accept these risks, with justification and criteria for acceptance.
5. Integration with ISMS Processes: Ensure that the implemented risk treatment controls are integrated with the organization's Information Security Management System (ISMS) processes and procedures.
6. Monitoring and Review: Monitor and review the effectiveness of the implemented controls and residual risk acceptance criteria, taking appropriate corrective actions as necessary.
7. Continuous Improvement: Continuously improve the risk assessment and risk treatment processes based on the monitoring and review activities, changes in the organization's context, and other relevant factors.
The intent of this clause is to ensure that organizations actively address the identified information security risks by implementing appropriate controls and risk treatment measures. It emphasizes the importance of a structured approach to risk treatment, including planning, implementation, monitoring, and continuous improvement, to effectively manage and mitigate information security risks within the organization's risk tolerance levels.
