Which of the following provides the MOST mitigation value for an organization implementing new Internet of Things (loT) devices?

Performing a vulnerability assessment is a reactive measure that identifies weaknesses after design or deployment; designing security in from the start is a more proactive and effective mitigation.

Designing security into the IoT architecture from the outset, often referred to as 'security by design,' ensures that fundamental security controls, such as secure boot, strong authentication, encryption, and secure updates, are baked into the devices and their ecosystem. This proactive approach significantly reduces the attack surface and mitigates a wide range of vulnerabilities before deployment, providing the highest mitigation value.

Implementing Key Risk Indicators (KRIs) helps monitor risk levels but does not directly mitigate vulnerabilities or build security into the devices themselves.

This option relates to risk trend data reporting, which is not a direct mitigation strategy for implementing new IoT devices.
