Internet of Things (IoT) Practice Exam

Which of the following is not a key principle of security for IoT gateways?

1. Strategy

2. Confidentiality

3. Integrity

4. Authentication

The correct answer is: Strategy

In the context of IoT gateways, key principles of security typically encompass aspects that directly relate to the protection of data and the systems involved in the IoT ecosystem. Confidentiality, integrity, and authentication are widely recognized as fundamental principles in cybersecurity practices. Confidentiality ensures that sensitive information is only accessible to authorized users, protecting data from unauthorized access. Integrity involves maintaining the accuracy and completeness of data, ensuring that it has not been tampered with or altered during transmission. Authentication confirms the identity of users or devices, preventing unauthorized access and ensuring that only legitimate entities can interact with the system. In contrast, while strategy is important for overall security planning and implementation, it does not serve as a foundational principle of security itself. Instead, strategy is more of an overarching concept that guides the application of the core principles like confidentiality, integrity, and authentication. Therefore, identifying strategy as not being a key principle of security for IoT gateways aligns with the understanding of these critical security tenets.
