What measures can prevent unauthorized access to IoT devices?

Unauthorized access to IoT devices can be prevented by enabling strong passwords, multi-factor authentication, and access control policies. These measures help ensure that only authorized users can access and control IoT devices, reducing the risk of malicious attacks and unauthorized access. Strong passwords should be unique and complex to make it harder for attackers to guess or brute force them. Multi-factor authentication adds an extra layer of security by requiring users to provide more than one form of verification, such as a password and a code sent to their phone. Access control policies help define who can access the devices and what actions they can perform, limiting the potential impact of unauthorized access.
