物联网安全：打造更好、更安全的互联世界。

As the rise of the Internet of Things enables new use cases, it is also multiplying the number of entry points that cybercriminals can exploit to launch attacks on connected systems. We have the tools to help you build a secure IoT, protect your business, and become part of the broader solution.

The fundamental question in security is always the same: what assets are you trying to secure, how much are they worth to others, and how much are you willing to invest to keep them safe. Perfect security doesn’t exist anywhere, and the Internet of Things is no exception. But better IoT security does, and companies are starting to invest in it. The GSMA  expects the IoT security market to grow at a CAGR of 36% from 2016 to 2021.

IoT Security breaches can hit businesses in three places. Say you are a utility. If hackers disable the smart gas meters you rely on for billing, they disrupt your revenues – your top line. When they feed faulty supply chain information into your system, they might increase your operational expenses, impacting your bottom line. And when they compromise your devices to penetrate into the local smart city network, they can end up exposing the entire system. Regardless of where they strike, they can make and break your business.

So read on to find out how to keep your data, your communications, and your networked systems safe.

IoT security for your devices

The first step is to ensure that you can fully trust and control your devices. For this, they need to be protected against attacks. Your devices need a unique and immutable identity and functions, such as trusted keys, to ensure their authenticity. For the highest level of security, these features should be baked into the hardware. Additionally, the firmware running on each device needs to be protected.

IoT security for your data flows

The next step is to ensure that the privacy of your data is protected all the way from the device to the cloud. The confidentially of your data needs to be ensured. Additionally, you need to be able to establish the integrity and authenticity of your data at all times. In IoT settings, which often involve thousands, if not millions, of devices, this requires highly efficient and scalable cryptographic methods.

Secure access to your data and devices

Finally, you need to be able to ensure that access to your devices, their features, and their data are restricted to trusted users, during fabrication, configuration, and operation. Any unauthorized access to your device has to be treated as a potential threat to your business. To manage and contain any intrusions, you need to be able to remotely revoke access to the broader network by any compromised devices.
