|IoT Security Market Watch—Key Market Needs and Solution Providers in the IoT Landscape|
|90% of Organizations to Consider Security as the Prime Consideration in IoT Deployments|
The future of Internet of Things (IoT) involves billions of connected devices (such as smartphones, computers, and sensors) communicating with one another, regardless of manufacturer, operating system, chipset, or physical transport. However, security is essential for reliable IoT operations. Whether malicious or accidental, malfunctioning IoT devices such as a connected car or components of a smart grid can pose a significant risk to consumers, businesses, and societies. Therefore, it is essential to protect IoT devices in order to realize the full potential of IoT.
The key considerations for complete and effective IoT cybersecurity include: 1) Operating within the physical and technical limitations of IoT by using efficient and lightweight security technologies; 2) The ability to accommodate multiple security approaches, including digital certificate-based or certificate-less security mechanisms; 3) The protection of IoT data at rest, in transit, and in the cloud; 4) A standards-based approach for IoT security; and 5) Operating at scale to support millions of IoT devices with no impact on speed and security of IoT operations.
