An internet of things (IoT) connection can help give you a real-time unified view of your business’s operations, simplifying task supervision. On the flip side, it can increase your risk for data breaches, as a vulnerability in a single device can provide hackers with a gateway into your entire business system. To increase your business data safety, you need a robust cybersecurity strategy that considers each of the devices in the connection. Here are a few tips to help you build it:
1. Use the right infrastructure
As you probably know, some devices are more secure than others, even before taking any data security measures. To improve your wireless infrastructure, make sure to involve an expert that is au fait with cybersecurity practices. Involve them in each stage, from choosing infrastructure to installing and maintaining it, for more consistent performance and easier problem identification.
2. Utilize device discovery
One of the easiest ways to spot malicious activity within the business’s IoT network is to have complete visibility of all the connected devices. Develop a way to discover the types of devices connected to the network. Note the brand and model names, hardware, serial number, and software versions. Review each device’s security risk profile and behavior when used alone and when connected to your network. Once you have all the data, create a firewall policy that takes into consideration all the risks you identified.
3. Adopt a strong password strategy
Password attacks on IoT devices are not very common, but they can cause devastation to a business’s entire network when they happen. For that reason, it is important to ensure each IoT device has a strong password.
Note that most IoT devices have preset passwords that you may be tempted to keep because they appear strong, but these can be figured out if hackers know your device manufacturer. Do not connect any device to the network before resetting its authentication credentials. Also, ensure the same password is not used on more than one device.
4. Monitor your IoT devices
Management of a business’s IoT security risks is easiest and most effective when the assets are monitored in real-time. This is because most conventional endpoint security solutions are only compatible with software that most IoT devices cannot host. Your in-house IT team can help you implement a monitoring strategy.
5. Run the latest firmware
Just like your company computers, smart devices in your IoT connection receive regular firmware updates to increase functionality and fix security flaws. Many business owners often forget or avoid updating their devices’ software because it involves accessing their interface from another device. This can be dangerous as it leaves your devices exposed to vulnerabilities that hackers have been made aware of. Ensure all your IT assets come with firmware that can be updated and that you install updates as soon as they are made available.
Endnote
Your IoT network is a prime target for hackers as it carries numerous devices—each with its set of security flaws. Use the above tips to increase its security and prevent hackers from getting hold of your business data.
