Tips to Strengthen Internet of Things (IoT) Cybersecurity


As the entire globe is merging into a network of connected objects, machines, and devices, the Internet of Things (IoT) is one of the most embraced technologies in the business and consumer landscape.

A weave of IoT networks enables businesses to embrace devices with integrated sensors to gather and evaluate information and share it with the rest of the network.

Enterprises of all sectors, sizes, and industries are integrating IoT devices into their industrial control systems, factory floors, and other areas to streamline the workflow. According to a recent report by Markets and Markets titled “Internet of things market,” the market size of IoT is expected to grow from USD 300.3 billion in 2021 to USD 650.5 billion by 2026. The report also highlights that the IoT market size will witness a 16.7% CAGR in the forecasted period from 2021 to 2026.

Integrating the internet of things devices in the enterprise tech stack might expose them to vulnerable cyber threats and vulnerabilities. Moreover, the surge in the adoption of IoT devices has provoked cybercriminals to exploit their flaws in them to infiltrate the IT infrastructure.

CISOs should consider developing a robust internet of things cybersecurity framework to minimize cyber threats and avoid data breach incidents.

Here are a few strategies to strengthen the internet of things cybersecurity posture:

Maintaining a real-time device inventory

At the core of the enterprise IoT ecosystem, it is essential to know what all assets, devices, and networks are used. Enterprises need to add the IoT device into the asset inventory before deploying it to the IT infrastructure. CISOs should consider implementing regular network audits to validate all the authorized devices on the business network and their location. Moreover, with these audits, businesses can identify all the devices and assets with unauthorized access and remove them.

Update the default password of internet of things assets

It is a cakewalk for malicious actors to crack the default password set by the enterprises for their IoT systems. Once the cybercriminals have fingerprinted a device in a scan, they can access the entire network if the default passwords are still set. CISOs should consider updating the default passwords as a standard protocol for configuring a new IoT asset.

Update the IT infrastructure with advanced firmware

Enterprises’ cybersecurity protocols might get hampered because of a weak link in the entire business network. Organizations can evaluate the entire internet of things infrastructure to spot the potential threats to the enterprise network. Exploring, evaluating, and implementing advanced firmware to protect against cyber threats will help to strengthen the internet of things cybersecurity.

Set a different Wi-Fi network for the IoT devices

Usually, IoT devices have very basic or no integrated security protocols to protect business networks. Enterprises need to set processes that enable information sharing between the devices only when required. Moreover, businesses need to avoid storing sensitive information on IoT devices. CISOs should consider setting up a different Wi-Fi network for all the IoT devices. It is one of the most effective ways to minimize the risk to the enterprise’s IT infrastructure, even if the IoT devices are compromised. Businesses can strengthen IoT cybersecurity by adding additional security layers.

Design and implement robust penetration testing protocols

It is essential to adopt penetration testing approaches both while implementing a new IoT device and while it’s connected. Taking recommendations from a skilled IoT penetration tester will help enterprises to evaluate the potential security risks before adding them to the business network.
