ISO 27001 Clause 10.2 Continual Improvement, An organization maintains its ISMS continuously to ensure that it is fit for purpose, adequately comprehensive, and effective.
Why is continuous improvement important for an organization?
It is impossible for organizations, nor their contexts, to remain static. Additionally, the threats to information systems, as well as the methods of exploiting them, are rapidly evolving. Ultimately, there is no ISMS that can remain perfect; it must act as a constant tempo of improvement; however, an organization’s context and internal dynamics remain the same.
To illustrate non-conformity or risk-related improvements, an analysis of ISMS components (based on the adequacy, suitability, and effectiveness criteria) may show that the component exceeds ISMS requirements or is inefficient. Changing the management system can often improve the ISMS.
Improvements to be made:
– Internal audits regularly
– Conduct regular and proper management reviews (Clause 9.3 ISO 27001)
– External audits regularly
– Implementing suggestions from stakeholders into the information management system according to their tastes
– Maintaining a record regarding whether the organization is following Regulatory policies
– Reassessing security controls
– Matching organizational activities to ISO 27001 requirements
The top management can also set objectives for continuous improvements, such as measuring effectiveness, cost, or process maturity. Information system management is regarded as a critical component of business operations. To stay current with developments, the ISMS is periodically reviewed to ensure it functions, is effective, and is consistent with the organization’s goals.
What are the requirements for doing the assessment?
1. The suitability of the ISMS is assessed by considering the external and internal issues, as well as the requirements of the relevant parties, and addressing the outlined information security objectives and identified information security risks through both planning and implementing the ISMS.
2. Using ISMS adequacy to evaluate how well ISMS processes, practices, and processes meet the organizational goals, practices, and processes.
3. The effectiveness of the ISMS, in terms of whether the intended outcome(s) is achieved, the wishes of the interested parties are met, information security risks are controlled to meet goals, nonconformities are dealt with, and resources needed for the development, continual improvement, and maintenance of the ISMS support those outcomes.
Also included in the assessment can be an overview of the efficiency of the ISMS and its components. This can include evaluating whether the system is effectively using its resources and whether improvements can be made to achieve greater efficiency. Nonconformities can also be managed with corrective actions to identify areas of improvement.
Following identification of the area(s) for improvement, a consistent approach should be followed to maintain them:
1. Identify whether or not they should be pursued;
2. Determine the best approaches for addressing the opportunities so that benefits are realized, and nonconformities are avoided, or plan for corrective actions for nonconformities that do occur;
3. Assess the success of the actions taken.
