IoT devices pose which major security risk?

• A. High memory usage.
• B. Weak authentication and insecure interfaces.
• C. Excessive bandwidth.
• D. Interoperability with legacy systems.

Answer: (B)

The main risk with IoT devices stems from weak authentication and insecure interfaces. Many IoT devices are designed with limited computing power and resources, which leads to shortcuts in security—such as default or easily guessable credentials, little or no authentication for APIs, and insecure web or cloud interfaces. When these interfaces aren’t properly protected, attackers can gain unauthorized access, control the device, exfiltrate data, or use the device as a foothold to pivot into other parts of the network. Once a device is compromised, it can be turned into a foothold for broader attacks, including botnets that target other systems. Mitigation centers on stronger, unique authentication, disabling default credentials, securing interfaces with proper authentication and encryption, keeping firmware up to date, and segmenting networks to limit movement if a device is breached. While memory usage, bandwidth, or compatibility with older systems can pose other challenges, they don’t capture the immediate security danger IoT devices present in terms of unauthorized access and exposed interfaces.
