What Is IoT Security?
IoT security covers both physical device security and network security, and impacts the processes, technologies, and measures necessary to protect IoT devices and networks. It spans industrial machines, smart energy grids, building automation systems, entertainment devices, and more, including devices that often aren’t designed for network security. IoT device security must protect systems, networks, and data from a broad spectrum of IoT security attacks, which target four types of vulnerabilities:
- Communication attacks on the data transmitted between IoT devices and servers.
- Lifecycle attacks on the IoT device as it changes hands from user to maintenance.
- Attacks on the device software.
- Physical attacks, which directly target the chip in the device.
A robust IoT security portfolio allows developers to protect devices from all types of vulnerabilities while deploying the security level that best matches their application needs. Cryptography technologies help combat communication attacks, while security services can protect against lifecycle attacks. Isolation measures can be implemented to fend off software attacks, and tamper mitigation and side-channel attack mitigation technologies are essential against physical attacks on the chip.
