IoT devices are naturally vulnerable to . . . . . . . . threats.

Solution(By Examveda Team)

IoT devices are inherently susceptible to various security threats due to their interconnected and often resource-constrained nature. The interconnectedness of these devices exposes them to potential vulnerabilities that malicious actors can exploit to gain unauthorized access, manipulate data, or disrupt operations. As IoT devices collect and transmit sensitive data, inadequate security measures can result in data breaches and privacy violations.

Option A: Sensors are components of IoT devices that gather data from the environment. While they can be exploited in some attack scenarios, they are not the main reason for IoT device vulnerability.
Option B: Heterogeneity refers to the diversity of devices and technologies in IoT ecosystems. While it can complicate security measures, it is not the primary cause of vulnerability.
Option D: Connectivity is a fundamental aspect of IoT but is not inherently a threat. However, the way devices are connected can introduce vulnerabilities if not properly secured.

Therefore, the correct answer is Option C: security. IoT devices are naturally vulnerable to security threats due to their interconnected and resource-limited nature.
