I27001F Exam Dumps - Certified ISO/IEC 27001:2022 Foundation

The three fundamental properties of information security are confidentiality, integrity, and availability, often referred to as the CIA triad. Confidentiality means information is accessible only to authorized persons or entities. Integrity means safeguarding the accuracy and completeness of information. Availability means information and associated assets are accessible and usable when required. These principles are foundational within ISO/IEC 27001 and ISO/IEC 27002. Therefore, option B is correct.

=======

ISO/IEC 27001:2022 places strong leadership obligations on top management. These include ensuring that the resources needed for the ISMS are available, promoting continual improvement, supporting persons to contribute to the effectiveness of the ISMS, and communicating the importance of effective information security management. Because all the listed activities are aligned with top management responsibilities, the correct answer is D.

=======

The PDCA cycle stands for Plan, Do, Check, Act. It is a management model commonly associated with management systems, including the implementation and continual improvement of an ISMS. In the context of ISO/IEC 27001:2022, this logic supports planning the ISMS, implementing and operating it, monitoring and reviewing performance, and taking actions for continual improvement. Therefore, option B is correct.

=======

A well-implemented ISMS helps build trust and confidence among interested parties by demonstrating that information security risks are being managed systematically and effectively. Completely preventing all incidents is unrealistic and not required by ISO/IEC 27001:2022. Promoting good practices is important, but the broader organizational outcome recognized as a major success factor is increased confidence by customers, partners, regulators, and other interested parties. Therefore, option D is the best answer.

In ISO information security terminology, authenticity means the property that an entity is what it claims to be. This concept is distinct from non-repudiation, which relates to the ability to prove that an event or action occurred and cannot later be denied. It is also distinct from integrity, which concerns accuracy and completeness. Therefore, option B is correct.
