Best Practices in IIoT Cybersecurity

Cybersecurity has become a priority for almost all businesses. Hacking and other forms of data breach have evolved over time, making it hard for organizations to protect their data and systems from being compromised.

What is IoT?

The industrial internet of things (IoT) is a system made of internet-connected objects that can connect, collect and share data through a wireless network that doesn’t involve human intervention.

This technology has improved the efficiency of many industrial organizations. However, this has been accompanied by even more risks. Here are some security practices that are needed to enhance IIoT security:

1. End-to-End Encryption

For the security of the organization’s data streams, end-to-end encryption should be put into place. This will ensure that there is minimum or no data interception whatsoever.

Data transmission in any organization can be subject to attack if it operates outside a recommended firewall, there is no end-to-end encryption for the data, and a connection between external devices with the company’s gateway.

To avoid all this, end-to-end encryption of the data will ensure that external devices can’t connect to the main gateway. With this, the data stream will be transmitted over a secure connection that is impregnable.

2. Invest in Staff Training

Every organization that is dedicated to cybersecurity should ensure that its staff is well-trained on the same. Any event of an attempted data breach should be met with adequate preparedness from the staff in general.

They should be able to improve the company’s industrial infrastructure and enhance data security where it’s vulnerable. Any organization that invests in its staff’s cybersecurity training will always be one step ahead in case of any cyber attack.

3. More Secure Data Access

To enhance data security, companies should ensure that there are thorough authentication and authorization procedures. Strong and unique passwords should be used to access the company’s computer system.

These passwords, however, should be given to a few and trusted employees to ensure that all data is secured. With a secure credential system, firms are guaranteed no data breach, both internally and externally.

4. Understand the Security Concerns

While trying to secure IIoT, it’s important to understand all the security concerns that might arise in the future and fix them in advance. Issues like faulty data patches, network problems, and lack of clarity about assets ownership should be addressed.

When you understand that your systems have network problems, you’re able to fix that and ensure that hackers will not use that as a loophole to gain access to your systems.

5. Selective Sensor Connections

Having sensors essential to operating production line equipment connected to other sensors based on distance is risky for businesses. To ensure enhanced security and minimal data breach of the related company systems, these sensors should only connect other digitally linked sensors.


The above-listed security practices are essential for any company that wants to ensure data security and increased productivity. With the right cybersecurity measures in place comes peace of mind for any organization.
