What Is IoT Security?
IoT security includes both physical device security and network security, encompassing the processes, technologies, and measures necessary to protect IoT devices as well as the networks they’re connected to. It spans industrial machines, smart energy grids, building automation systems, employees’ personal IoT 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, which put the data transmitted between IoT devices and servers at risk.
- Lifecycle attacks, which put the integrity of the IoT device as it changes hands from user to maintenance.
- Attacks on the device software.
- Physical attacks, which target the chip in the device directly.
A robust IoT security portfolio allows developers to protect their devices from all types of vulnerabilities while deploying the security level that best matches their application needs. Cryptography technologies are used to combat communication attacks. Security services are offered for protecting against lifecycle attacks. Isolation measures can be implemented to fend off software attacks. And, finally, IoT security should include tamper mitigation and side-channel attack mitigation technologies for fighting physical attacks of the chip.
