This could include information on update policies, data handling practices, and known vulnerabilities.
• Clear Privacy Policies: Manufacturers must provide easily accessible and understandable privacy policies that detail what data is collected, how it is used, stored, and shared, and how users can control their data.
• End-of-Life Policies: Information on how long devices will receive security updates and support, and how to securely dispose of or repurpose devices at the end of their useful life, will be crucial.

3. Data Protection and Privacy

With IoT devices often collecting sensitive personal and operational data, robust data protection and privacy measures are paramount. The new guidelines will likely align with and strengthen existing data privacy regulations, such as the California Consumer Privacy Act (CCPA) and potentially future federal privacy laws. Key aspects include:

• Encryption Standards: Mandating the use of strong encryption for data in transit and at rest, both on the device and when communicated to cloud services.
• Access Controls: Implementing stringent access controls to prevent unauthorized access to device data and functionality.
• User Consent: Requiring explicit user consent for data collection and sharing, particularly for sensitive data.

4. Supply Chain Security

The security of an IoT device is only as strong as its weakest link, and often, these weaknesses originate in the supply chain. The 2026 IoT Security Guidelines are expected to place significant emphasis on supply chain integrity, requiring manufacturers to ensure that components and software sourced from third parties also adhere to robust security standards. This includes:

• Supplier Vetting: Implementing rigorous vetting processes for all suppliers of hardware and software components.
• Software Bill of Materials (SBOM): Requiring manufacturers to provide a “nutrition label” for their software, detailing all constituent components, their versions, and known vulnerabilities.
• Secure Development Practices: Encouraging or mandating secure coding practices among all supply chain partners.

Quantum-Resistant Cryptography

The advent of quantum computing poses a long-term threat to current cryptographic standards. As quantum computers become more powerful, they could potentially break many of the encryption methods currently used to secure IoT data. Research and development in quantum-resistant cryptography (also known as post-quantum cryptography) are already underway, and we can expect these new cryptographic primitives to be integrated into future IoT Security Guidelines to future-proof devices against quantum attacks.

Increased Focus on Edge Security

With more processing and data analysis moving closer to the source of data generation (the “edge” of the network), edge security will become even more critical. Securing edge devices and gateways will involve not only protecting against external attacks but also ensuring the integrity of data processing and decision-making at the local level. This reduces reliance on cloud connectivity for immediate responses and enhances privacy.

Privacy-Enhancing Technologies (PETs)

Beyond basic encryption, future IoT Security Guidelines will likely emphasize the adoption of advanced Privacy-Enhancing Technologies (PETs). These include techniques like homomorphic encryption (allowing computations on encrypted data), differential privacy (adding noise to data to protect individual identities), and secure multi-party computation (allowing multiple parties to jointly compute a function over their inputs while keeping those inputs private). These technologies will enable greater data utility while maintaining stringent privacy controls.
