IoT Landscape
- Billions of IoT devices are deployed globally, with predictions of rapid growth to 75 billion.
- Healthcare, manufacturing, and critical infrastructure are key sectors utilizing IoT, but personal devices are also increasing.
Vulnerable Devices
- Infusion pumps are numerous in healthcare (44% of devices) but pose fewer security risks (2%).
- Medical imaging systems (16% of devices) cause over 50% of cybersecurity issues due to full-blown OS and lack of updates.
IoT Security Challenges
- IoT devices face security challenges due to infrequent updates and patches, unlike frequently replaced IT devices.
- Many IoT devices operate in regulated industries where updates can disrupt operations and require recertification.
