Question
A smart home system is compromised, and attackers
remotely control connected devices like security cameras and smart locks. Which security principle is most critical to address this breach?Solution
The attack involves unauthorized access to IoT devices, making authentication the key concern. Strong authentication measures, such as multi-factor authentication (MFA) or device-specific credentials, can prevent attackers from gaining control. Proper authentication ensures: 1. Only authorized users or systems can access IoT devices. 2. Secure communication between devices in the IoT ecosystem. 3. Reduced risk of breaches even if other vulnerabilities exist. The lack of robust authentication exposes devices to unauthorized control, which was likely exploited in this scenario. Why Other Options Are Incorrect: • A) Confidentiality: Protects data but doesn't prevent unauthorized access to devices. • B) Availability: Ensures system uptime but doesn’t address access control. • C) Integrity: Focuses on preventing data tampering, not unauthorized access. • E) Non-repudiation: Prevents denial of actions but doesn’t secure initial access.
