In just a few short years, industry experts predict that the Internet of Things (IoT) will have a tremendous growth explosion. By the year 2020, research suggests 30 billion devices will be connected in a $3 trillion marketplace. Assuring that this avalanche of data is protected by layers of security is paramount to the industry’s success.
Soon there will be homes where the front doors unlock with a smartphone, its temperature is controlled remotely, and even the oven is turned on by punching a code. “Smart homes” are already on the technological horizon, but the security features must keep pace for viability.
Consumers own many devices that are not just unencrypted, but with marginal to non-existent security features enabled. Some end users leave the factory-set passwords in place, making illegally accessing a device’s data mere child’s play for the average hacker.
Making IoT Devices Secure
Certain qualities are required in order to make the security on IoT devices effective. The security must:
- Possess cloud capabilities
- Be platform agnostic
- Have the ability to facilitate IoT technological ecosystems
- Be lightweight
The ability to manage security via a cloud platform is a vital component to any implemented system. Cloud management enables manufacturers to patch changes to security configurations once a weak spot is detected – even after consumers purchase the device. The hardware itself can be tethered to private key exchanges to simplify authentication, provisioning, and configuration.
The benefits of utilizing agnostic security platforms are clear. Processing capabilities in IoT devices can enable them to be managed and controlled via the cloud. Transmitting large-scale changes in provisioning, authenticating, and configuring can also be handled at cloud level from a centralized location.
Compact IoT devices with security features embedded at the chip is a practical solution for securing data at the core of the device while still utilizing available space. IoT devices can have private keys already embedded to enhance security. This additional layer of security allows compromised components to be identified as “untrusted” and isolated from the other devices on the network. Default passwords would no longer be necessary once key exchanges are implemented within the hardware to authenticate each device. This also allows them to remain lightweight.
Issues to Overcome with IoT Devices
However, the lightweight, compact size of IoT devices limits the space available for security. Another drawback is the multiple levels of vulnerability when connecting devices or at the data host site of the chip. In addition, the limitations of the processing capabilities on devices manufactured by different companies creates security challenges. At present, consumers must use devices made by the same company in order to link them. Cloud-based connections reduce the necessity of standardizing the processing capabilities of IoT devices.
Most IoT devices aren’t currently enabled for cloud management, which is a potential security pitfall. When devices are all tethered to the cloud, it is a simple fix to patch security vulnerabilities – even when they are in the hands of end users. Devices can communicate more readily with one another when cloud capabilities have been implemented.
The bottom line is that the success of the IoT industry is dependent upon the security that is provided by the technology. To ensure that data protection remains a primary focus in an expanding market, networks and devices must be safeguarded. Enabling cloud management capabilities and security features embedded at the chip level can achieve these results.
