An IoT endpoint is a network-connected device that performs a specific job, such as a camera, sensor, printer monitor, or smart appliance. Unlike a simple gadget, it usually runs embedded firmware, has a network address, and may expose web interfaces, APIs, or cloud connections. Because it is always online and often deployed in large numbers, it should be treated like a managed computer, not a passive device.
In cyber security, IoT endpoints matter because they can become entry points for attackers if they use weak passwords, outdated firmware, open services, or insecure remote access. Compromised devices are commonly abused for spying, lateral movement, botnets, or pivoting into a home or business network. Defenders reduce risk by changing default credentials, keeping firmware updated, disabling unnecessary services, segmenting the network, and monitoring device behavior. When a camera or similar device is repurposed, the trust model changes too, so active security management becomes essential.
