What are common IoT security practices to secure connected devices?

• A. Change default passwords, keep firmware updated, segment IoT networks, and disable unnecessary services.
• B. Use the same password across devices.
• C. Disable firmware updates.
• D. Connect IoT devices to untrusted networks.

Answer: (A)

Securing IoT devices relies on reducing attackers’ chances to gain access and keeping devices resilient against exploits. The best approach is to change default passwords to unique, strong ones, keep firmware updated to patch known vulnerabilities, segment IoT devices on their own network to limit lateral movement, and disable unnecessary services to shrink the attack surface. Using the same password across devices creates a single point of compromise—once one device is breached, others become easy targets. Disabling firmware updates leaves known flaws unpatched, making devices vulnerable. Connecting IoT devices to untrusted networks greatly increases the risk of interception, malware, and unauthorized access.
