The Internet of Things (IoT) is a vast network of interconnected devices — from smart cameras and sensors to industrial controllers.
It drives automation, analytics, and efficiency, but it also introduces new attack vectors.
That’s why IoT security has become a top priority in every organisation’s cybersecurity strategy.
What is the Internet of Things (IoT)?
IoT refers to physical devices that communicate and exchange data over networks, often without direct human interaction.
While it dramatically improves operational efficiency, it also introduces risks stemming from:
- lack of firmware updates,
- factory-default credentials,
- poor network segmentation,
- absence of monitoring.
Most Common IoT-Related Threats
| Threat Type | Description |
|---|---|
| DDoS Attacks | Thousands of compromised IoT devices turned into botnets (e.g., Mirai) to overwhelm targets. |
| Unauthorised Access | A single unsecured IoT device can serve as an entry point into the corporate network. |
| Weak/Default Passwords | Default credentials remain the most common initial access vector. |
| Unpatched Firmware | Known vulnerabilities in outdated software are routinely exploited. |
How to Secure IoT Devices
- Change default credentials immediately after deployment – use strong, unique passwords.
- Segment the network – isolate IoT devices from critical business systems (VLANs, firewalls, or micro-segmentation).
- Keep firmware updated – apply manufacturer security patches on a regular schedule.
- Restrict access – enforce the principle of least privilege and control remote connections.
- Disable unnecessary features – turn off remote management interfaces when not required.
IoT Monitoring and Management
Effective protection demands continuous visibility and control:
- Network traffic monitoring – detect anomalies in IoT device communication patterns.
- Access management – log all access attempts, enforce MFA, and use strong authentication.
- Regular IoT security audits – periodically review configuration and scan for vulnerabilities across the entire device fleet.
Train Your Team on IoT Security
Even the best technology cannot replace user awareness.
Train employees to:
- recognise IoT-related risks,
- properly configure and update devices,
- report suspicious device behaviour promptly.
An aware workforce is your first line of defence.
Secure Your IoT Ecosystem Today
Implement robust IoT protection strategies to safeguard your data, networks, and reputation.
Regular updates, traffic monitoring, network segmentation, and user education turn IoT from a liability into a secure asset.
