One notable development is the IoT Cybersecurity Improvement Act of 2020, signed into law by former President Trump. This legislation empowers the National Institute of Standards and Technology (NIST) to manage IoT cybersecurity risks for devices acquired by the federal government, establishing minimum security standards for connected devices used by federal agencies.

State-Level Regulations

At the state level, California and Oregon have taken the lead in IoT cybersecurity regulations. In 2018, the California legislature passed SB-327, which requires IoT devices sold in the state to be equipped with “reasonable security features” to protect the device and its associated data. Similarly, Oregon enacted HB-2395, a law with similar requirements.

Industry-Specific Regulations

While the U.S. lacks a comprehensive IoT cybersecurity framework, specific industries have their own regulatory requirements that impact the IoT. For instance, the healthcare sector must comply with the Health Insurance Portability and Accountability Act (HIPAA), which includes provisions for the security of connected medical devices. The financial industry is subject to the Gramm-Leach-Bliley Act (GLBA), which sets data privacy and security standards for financial institutions.

Furthermore, the patchwork of state-level privacy laws, such as the California Consumer Privacy Act (CCPA) and the New York SHIELD Act, have indirect implications for IoT cybersecurity, as they mandate the protection of personal data collected by connected devices.

While the U.S. regulatory approach may seem less cohesive compared to the EU’s, it underscores the importance for businesses to closely monitor industry-specific and state-level regulations that may impact their IoT product development and deployment.

Navigating the U.K.’s IoT Cybersecurity Regulations

The United Kingdom has also taken significant strides in addressing IoT cybersecurity, aligning its efforts with the broader regulatory landscape in Europe. The introduction of the Product Security and Telecommunications Infrastructure (PSTI) Act in 2024 marks a critical milestone in the U.K.’s IoT cybersecurity regulations.

The PSTI Act shifts the responsibility for securing IoT devices away from consumers and onto the manufacturers and providers of these products. It mandates compliance with specific product safety requirements, including:
