According to ISO/IEC 27001:2022 clause 7.2, the organization must ensure that the persons doing work under its control are aware of the information security policy, their contribution to the effectiveness of the ISMS, the implications of not conforming to the ISMS requirements, and the benefits of improved information security performance. The organization must also provide information security awareness education and training to its personnel and relevant interested parties. According to control A.6.3, the organization must ensure that all employees and contractors are made aware of the information security incident management procedures and their expected roles and responsibilities. Therefore, an opportunity for improvement (OFI) can be identified if the information security incident training effectiveness can be improved, as evidenced by the differences in the understanding of the meaning of "weakness, event, and incident" among the staff.
According to ISO/IEC 27001:2022 clause 9.1, the organization must monitor, measure, analyze and evaluate the information security performance and the effectiveness of the ISMS. The organization must also retain appropriate documented information as evidence of the monitoring and measurement results. According to control A.5.24, the organization must establish and maintain an information security incident management process that includes the following activities:
* reporting information security events and weaknesses;
* assessing and deciding on information security events;
* responding to information security incidents;
* learning from information security incidents;
* collecting evidence and disclosing information.
Therefore, a nonconformity (NC) can be identified if the terminology of the incident management reporting process is unclear, as evidenced by the staff misunderstanding of the meaning of "weakness, event, and incident". This could lead to inconsistent or inaccurate reporting, assessment, response, learning, and disclosure of information security incidents, which could affect the information security performance and the effectiveness of the ISMS.
