IoT Security

Definition

IoT security covers the protection of connected devices: smart devices, industrial sensors, cameras, medical equipment and more. IoT devices often have limited security features.

IoT security covers the protection of Internet of Things devices: smart devices, industrial sensors, cameras, medical equipment and more. The number of IoT devices is expected to grow to 30 billion by 2030, but security problems are increasing proportionally. The Mirai botnet demonstrated the risks in 2016 by using thousands of unsecured IoT devices for a 1.2 Tbps DDoS attack.

How does IoT security work?

IoT devices have unique security challenges: limited computing power preventing traditional security software, missing or insecure update mechanisms, default passwords rarely changed, unencrypted communication protocols, long lifespans running outdated software, and large numbers making management complex.

Impact on organisations

Every IoT device is a potential access point for attackers. In corporate environments, IoT devices connect to the network and can serve as springboards for further attacks. In industrial environments (IIoT), compromised sensors can lead to production disruption or safety incidents. The CRA introduces mandatory security requirements for IoT products. NIS2 requires adequate security for all network-connected devices.

Protection

Change default passwords on all IoT devices. Segment IoT devices in a separate network. Monitor IoT traffic for anomalies. Keep firmware updated. Choose IoT devices supporting security updates. Implement NAC.

How DEFION helps

DEFION conducts IoT-related security assessments as part of Cloud Security Assessments and OT Security services.
