IoT Security and Why it Matters
- OCTOBER 6TH, 2025

Internet of Things (IoT) devices are smart devices, embedded with sensors, software, and Wi-Fi connectivity, to collect and exchange data over the Internet. This includes smart thermostats, wearable fitness trackers, internet cameras and industrial sensors. IoT security includes a range of measures and technologies used to secure networked devices, and includes all the steps taken to protect connected devices from various types of security attacks, such as the Mars Hydro IoT Nightmare.
Why IoT Security Matters
IoT security is important for the following reasons:
- Protection of Critical Systems and Data: From personal data to operational data points, connected devices gather and process large amounts of sensitive information. Leaked data causes financial and compliance losses, and disrupted operations lead to costly downtimes, as well as possible damage to equipment.
- Prevention of Network-Wide Compromises: IoT devices can be an entry point into bigger organisational networks. When the devices are not secured, once they are compromised, they can be used by attackers to navigate through the network.
- Securing Physical Operations and Safety: IoT devices often interface directly with physical systems, and thus, their security is paramount to operational safety.
IoT Security Best Practices
Follow these steps to minimise risk:
- Secure Device Configuration: Change the default device settings and set-up encryption for all storage/transmission of data, configuring secure protocols where remote access is enabled, and having strong authentication in place.
- Network Security Implementation: Network segmentation helps isolate IoT devices from critical business systems, which minimises potential security breaches.
- Security Monitoring and Response: Network monitoring systems, like TrendMicro, monitor the behaviour of devices and identify abnormal traffic patterns that suggest there may be a security issue.
- Update Management Process: Updating software/firmware versions has essential implications for system security, enabling IoT devices to mitigate against known vulnerabilities.
- Access Control Systems: Companies must ensure that role-based access control systems are in place, limiting user privileges to only those needed according to their job.
