Local laws and regulations should be the primary consideration when assessing the risk of using Internet of Things (IoT) devices to collect and process personally identifiable information (PII), because they define the legal and ethical obligations and boundaries for the protection and privacy of PII, and the potential consequences of non-compliance or violation. IoT devices are devices that are connected to the internet and can collect, transmit, or process data, such as smart watches, cameras, sensors, or appliances. PII is information that can be used to identify, locate, or contact an individual, such as name, address, phone number, or email address. PII is considered sensitive and confidential, and may be subject to various laws and regulations that govern how it should be collected, processed, stored, shared, or disposed, such as the General Data Protection Regulation (GDPR) in the European Union, or the California Consumer Privacy Act (CCPA) in the United States. Therefore, local laws and regulations should be the primary consideration, as they provide the legal and ethical framework and guidance for the use of IoT devices to collect and process PII, and the potential risks and impacts of non-compliance or violation. Costs and benefits, security features and support, and business strategies and needs are all possible considerations when assessing the risk of using IoT devices to collect and process PII, but they are not the primary consideration, as they may vary or conflict depending on the situation or context, and may not override the local laws and regulations.
