Editorial Security, Reliability, and Resilience in Internet of Things

The Internet of Things (IoT) has become a popular platform that supports various services, such as smart homes, industrial applications, microsurveillance systems, and smart city services. IoT connects physical devices, such as sensors, thermostats, cell phones, laptops, and servers, and enables them to collect and exchange data. It has been predicted that the number of IoT devices will reach billions by the year of 2025. These sensing devices often generate large amounts of sensitive data and communicate frequently through open channels at a high risk of being compromised. Due to the mission-critical nature of IoT applications, IoT devices must operate in a secure and reliable manner. Any network outage, data loss, or corruption during transmission or in storage can have catastrophic effects on the IoT applications. For their deployment, security and reliability assurance are essential. IoT devices may span multiple layers of the IoT architecture, (e.g., cloud, edge, and sensors) and vary in various service modes, critical levels, and connectivity. When an IoT device encounters unexpected events, it needs to automatically reconfigure its settings and operations, and sometimes even suspend its transmission in a way that cyber resiliency can be achieved.
