Certified Incident Handler (CIH) Practice Ecam

Which IoT threat restricts operators from changing default settings for better security?

1. Insecure default settings

2. Limited user permissions

3. Inadequate encryption methods

4. Weak password policies

The correct answer is: Insecure default settings

Insecure default settings pose a significant threat in the Internet of Things (IoT) landscape, primarily because these settings often leave devices vulnerable to exploitation. Many IoT devices come with factory settings that are not optimized for security; they frequently include default usernames and passwords that are easily guessable or publicly available. As a result, if operators are unable to change these settings, they may inadvertently leave the device exposed to attackers who can easily exploit these vulnerabilities. The inability to change default configurations prevents operators from implementing stronger security measures tailored to their specific environment, thus increasing the risk of unauthorized access. This threat is particularly concerning in IoT devices, which are often deployed in various settings and may not have the same level of direct management as traditional IT devices. A focus on changing these insecure default settings is critical for enhancing the overall security posture of IoT implementations.
