According to the ISO/IEC 27001 : 2022 Lead Implementer course, one of the objectives of information security incident management is to collect and preserve records that can be used as evidence for disciplinary and legal action, as well as for learning and improvement purposes1. Therefore, Anna should be aware of the collection and preservation of records when gathering data for the forensics team. She should follow the guidelines and procedures specified in the information security incident management policy of InfoSec, which defines the type, format, content, and location of the records to be created and maintained2. The records should be accurate, complete, consistent, and reliable, and should be protected from unauthorized access, modification, or deletion3.

Explanation
Risk modification is one of the four risk treatment options defined by ISO/IEC 27001, which involves applying controls to reduce the likelihood and/or impact of the risk. By requiring its employees to change their email passwords at least once every 60 days, Company A has implemented a risk modification option to reduce the risk of unauthorized access to its email accounts. Changing passwords frequently can make it harder for attackers to guess or crack the passwords, and can limit the damage if a password is compromised.
The other three risk treatment options are:
Risk avoidance: This option involves eliminating the risk source or discontinuing the activity that causes the risk. For example, Company A could avoid the risk of email compromise by not using email at all, but this would also mean losing the benefits of email communication.
Risk retention: This option involves accepting the risk and its consequences, either because the risk is too low to justify any treatment, or because the cost of treatment is too high compared to the potential loss. For example, Company A could retain the risk of email compromise by not implementing any security measures, but this would expose the company to potential breaches and reputational damage.
Risk transfer: This option involves sharing or transferring the risk to a third party, such as an insurer, a supplier, or a partner. For example, Company A could transfer the risk of email compromise by outsourcing its email service to a cloud provider, who would be responsible for the security and availability of the email accounts.

According to ISO/IEC 27001:2022, clause 9.3.3, the organization must retain documented information as evidence of the results of management reviews. The results of management reviews must include decisions and actions related to the ISMS policy, objectives, risks, opportunities, resources, and communication.
Documenting the results of management reviews is important to ensure the accountability, traceability, and effectiveness of the ISMS. It also helps the organization to monitor and measure the performance and improvement of the ISMS, and to demonstrate compliance with the requirements of ISO/IEC 27001:2022.
Therefore, an organization that has an ISMS in place and conducts management reviews at planned intervals, but does not retain documented information on the results, is not in accordance with the requirements of ISO
/IEC 27001.
