ISO/IEC 27001 focuses on the core principles of the CIA triad:
*Confidentiality: Ensuring information is accessible only to authorized individuals.
*Integrity: Maintaining the accuracy and completeness of information, protecting it from unauthorized modification.
*Availability: Information should be accessible to authorized users when needed (this is also important, but not one of the choices in this specific question).

*ISO/IEC 27001:2022, Section 4.2 (Understanding the needs and expectations of interested parties): This section highlights the importance of determining relevant interested parties and their requirements related to information security, which includes addressing confidentiality, integrity, and availability.

The three options of the corrections and corrective actions listed that you would expect ABC to make in response to the nonconformity are:
* B. ABC cancels the service agreement with WeCare.
* E. ABC introduces background checks on information security performance for all suppliers.
* F. ABC periodically monitors compliance with all applicable legislation and contractual requirements involving third parties.
* B. This option is a possible correction and corrective action that ABC could take to address the nonconformity. A correction is the action taken to eliminate a detected nonconformity, while a corrective action is the action taken to eliminate the cause of a nonconformity and to prevent its recurrence1. By cancelling the service agreement with WeCare, ABC could stop the unauthorized use of residents' personal data and protect their privacy and rights. This could also prevent further complaints and legal issues from the residents and their family members. However, this option may also have some drawbacks, such as the loss of a service provider, the need to find an alternative solution, and the potential impact on the residents' well-being.
* E. This option is a possible corrective action that ABC could take to address the nonconformity. By introducing background checks on information security performance for all suppliers, ABC could ensure that they select and work with reliable and trustworthy partners who respect the confidentiality, integrity, and availability of the information they handle. This could also help ABC to comply with information security control A.15.1.1 (Information security policy for supplier relationships), which requires the organisation to agree and document information security requirements for mitigating the risks associated with supplier access to the organisation's assets2.
* F. This option is a possible corrective action that ABC could take to address the nonconformity. By periodically monitoring compliance with all applicable legislation and contractual requirements involving third parties, ABC could verify that the suppliers are fulfilling their obligations and responsibilities regarding information security. This could also help ABC to comply with information security control A.18.1.1 (Identification of applicable legislation and contractual requirements), which requires the organisation to identify, document, and keep up to date the relevant legislative, regulatory, contractual, and other requirements to which the organisation is subject3.

B . This response is correct because the audit team leader should document the request of the Technical Director and include it in the audit report, along with the audit findings and conclusions12. This will ensure transparency and traceability of the audit process and the audit results.
D . This response is correct because the audit team leader should not withdraw the nonconformity based on the amended Statement of Applicability alone. The nonconformity was raised against clause 6.1.3.e of ISO 27001:2022, which requires the organisation to produce and maintain a risk treatment plan that defines how the information security risks are treated, including the controls selected and their implementation status34. The Statement of Applicability is only one part of the risk treatment plan, and it does not provide sufficient evidence that the controls have been implemented effectively. The audit team leader should base the nonconformity on the objective evidence obtained during the audit, not on the subjective claims of the auditee12.
H . This response is correct because the audit team leader should state that a follow up audit will be necessary to review the evidence for the updated Statement of Applicability. A follow up audit is an audit that is conducted after a previous audit to verify the implementation and effectiveness of the corrective actions and/or opportunities for improvement that were agreed upon as a result of the previous audit56. The follow up audit should seek to ensure that the nonconformity has been effectively addressed and that the ISMS is compliant and effective. The follow up audit should also consider any new or changed risks or requirements that may affect the ISMS56.
Explanation:
The three options of the correct responses of an audit team leader to the request of the Technical Director are:
B . Advise the Technical Director that his request will be included in the audit report.
D . Advise the Technical Director that the nonconformity must stand since the evidence obtained for it was clear.
