Based on scenario 5. after migrating to cloud. Operaze’s IT team changed the ISMS scope and implemented all the required modifications Is this acceptable?

Scenario 5: Operaze is a small software development company that develops applications for various companies around the world. Recently, the company conducted a risk assessment to assess the information security risks that could arise from operating in a digital landscape. Using different testing methods, including penetration Resting and code review, the company identified some issues in its ICT systems, including improper user permissions, misconfigured security settings, and insecure network configurations. To resolve these issues and enhance information security, Operaze decided to implement an information security management system (ISMS) based on ISO/IEC 27001.

Considering that Operaze is a small company, the entire IT team was involved in the ISMS implementation project. Initially, the company analyzed the business requirements and the internal

and external environment, identified its key processes and activities, and identified and analyzed the interested parties In addition, the top management of Operaze decided to Include most of the company’s departments within the ISMS scope. The defined scope included the organizational and physical boundaries. The IT team drafted an information security policy and communicated it to all relevant interested parties In addition, other specific policies were developed to elaborate on security issues and the roles and responsibilities were assigned to all interested parties.

Following that, the HR manager claimed that the paperwork created by ISMS does not justify its value and the implementation of the ISMS should be canceled However, the top management determined that this claim was invalid and organized an awareness session to explain the benefits of the ISMS to all interested parties.

Operaze decided to migrate Its physical servers to their virtual servers on third-party infrastructure. The new cloud computing solution brought additional changes to the company Operaze’s top management, on the other hand, aimed to not only implement an effective ISMS but also ensure the smooth running of the ISMS operations. In this situation, Operaze’s top management concluded that the services of external experts were required to implement their information security strategies. The IT team, on the other hand, decided to initiate a change in the ISMS scope and implemented the required modifications to the processes of the company.

Answer: C

Explanation:

According to ISO/IEC 27001:2022, clause 4.3, the organization shall determine the scope of the ISMS by considering the internal and external issues, the requirements of interested parties, and the interfaces and dependencies with other organizations. The scope shall be available as documented information and shall state what is included and what is excluded from the ISMS. The scope shall be reviewed and updated as necessary, and any changes shall be approved by the top management.

Therefore, it is not acceptable for the IT team to change the ISMS scope and implement the required modifications without the approval of the management.
