What it is
IoT exposure refers to Internet of Things devices such as cameras, sensors, routers, industrial controllers, or smart appliances that are accessible from the internet without adequate security controls. This often includes default credentials, outdated firmware, open management interfaces, or unencrypted communications.
Why it matters
IoT devices are frequently targeted because they are widely deployed, rarely monitored, and often poorly secured. Compromised IoT devices can be used for surveillance, data theft, network pivoting, or large-scale botnet attacks. In industrial or healthcare environments, IoT exposure can also create safety and operational risks.
How to reduce risk
- Inventory all internet-facing IoT devices.
- Change default credentials and disable unused services.
- Keep firmware and device software up to date.
- Segment IoT devices from core networks.
