What is the main purpose of IoTSF?

The primary purpose of the Internet of Things Security Foundation (IoTSF) is indeed as a collaborative, nonprofit response to cybersecurity challenges specifically within the Internet of Things (IoT) realm. IoTSF was established to address the urgent need for improved security practices as IoT devices proliferate and become more integrated into everyday life. It promotes security frameworks, provides guidelines, and establishes best practices to help organizations manage the inherent risks associated with IoT technologies.

In the context of this question, options related to developing new IoT technologies, monitoring government compliance, or creating hardware do not align with the organization's primary focus on enhancing security measures and providing resources to mitigate cybersecurity risks. Thus, the emphasis on collaborative efforts to tackle cybersecurity challenges solidifies the correctness of this choice as the core mission of IoTSF.
