Scenario 9: OpenTech provides IT and communications services. It helps data communication enterprises and network operators become multi-service providers During an internal audit, its internal auditor, Tim, has identified nonconformities related to the monitoring procedures He identified and evaluated several system Invulnerabilities.
Tim found out that user IDs for systems and services that process sensitive information have been reused and the access control policy has not been followed After analyzing the root causes of this nonconformity, the ISMS project manager developed a list of possible actions to resolve the nonconformity. Then, the ISMS project manager analyzed the list and selected the activities that would allow the elimination of the root cause and the prevention of a similar situation in the future. These activities were included in an action plan The action plan, approved by the top management, was written as follows:
A new version of the access control policy will be established and new restrictions will be created to ensure that network access is effectively managed and monitored by the Information and Communication Technology (ICT) Department
The approved action plan was implemented and all actions described in the plan were documented.
Based on scenario 9. did the ISMS project manager complete the corrective action process appropriately?
According to ISO/IEC 27001:2022, the corrective action process consists of the following steps12:
Reacting to the nonconformity and, as applicable, taking action to control and correct it and deal with the consequences
Evaluating the need for action to eliminate the root cause(s) of the nonconformity, in order that it does not recur or occur elsewhere
Implementing the action needed
Reviewing the effectiveness of the corrective action taken
Making changes to the information security management system, if necessary
In scenario 9, the ISMS project manager did not complete the last step of reviewing the effectiveness of the corrective action taken. This step is important to verify that the corrective action has achieved the intended results and that no adverse effects have been introduced.The review can be done by using various methods, such as audits, tests, inspections, or performance indicators3. Therefore, the ISMS project manager did not complete the corrective action process appropriately.
