IoT Security By Design
- The Internet of Things (IoT) is gaining momentum in mainstream business use, with global projections estimating 43 billion IoT-connected devices by 2030.
- The automotive industry's increased adoption of IoT devices, such as connected vehicles, is transforming modern vehicles into IoT devices on wheels.
- Security is crucial for IoT devices, with the IoT Security Foundation offering an assurance framework for enhancing security based on specific applications.
- In the automotive sector, a defense in depth approach, such as Siemens' Tessent product family, is essential for creating secure integrated circuits for automotive applications.
- Progress towards autonomous driving is measured against the six levels of autonomy defined by the Society of Automotive Engineers (SAE).
- Various standards like ISO 26262, ISO 21448, and ISO 21434 have emerged to ensure compliance with safety, functionality, and cybersecurity requirements in automotive systems.
- Hardware-based security solutions, including secure boot, attestation, secure access, asset protection, and device lifecycle management, play a significant role in safeguarding automotive ICs.
- Threat modeling using methodologies like STRIDE is essential to assess cybersecurity risks dynamically and adapt security measures to combat evolving threats effectively.
- Teams involved in threat modeling must deeply understand the threat landscape to accurately assess risks and vulnerabilities associated with different scenarios.
- Threat modeling tools, such as attack trees, help analyze attack scenarios and assess the cost to an attacker, requiring ongoing updates to remain effective.
