What are "IoT devices," and why do they pose a security risk?

The correct choice identifies "IoT devices" as "Internet of Things devices" and highlights the significant security risks they pose due to weak security features and unpatched vulnerabilities.

IoT devices encompass a wide range of products connected to the internet, including smart home devices, industrial sensors, and wearable technology. These devices often come with minimal security controls and are typically designed for ease of use rather than robust security. As a result, many IoT devices may have factory default passwords that users neglect to change, leaving them open to exploitation. Additionally, many IoT devices are not regularly updated with security patches, further exposing them to vulnerabilities that can be taken advantage of by cyber attackers.

The other options mischaracterize what IoT devices are or fail to fully capture the breadth of the security risks they present. Recognizing IoT devices' nature and their potential vulnerabilities is crucial for understanding the landscape of cybersecurity challenges they bring.
