Question
What are the major security and privacy challenges in IoT? Propose a security framework to mitigate these risks in a smart healthcare system.
Answer
IoT faces massive security challenges like data breaches and unauthorized access; mitigation requires a multi-layered framework.
Major security challenges in IoT include: - Insecure Interfaces: Web, mobile, or cloud APIs that lack proper authentication. - Lack of Encryption: Data transmitted in plaintext can be intercepted. - Physical Vulnerability: Devices deployed in the open can be tampered with. - Privacy: In systems like smart healthcare, highly sensitive patient data is continuously generated.
Proposed Security Framework for Smart Healthcare: 1. Device Level: Use hardware-based trusted execution environments and secure boot processes for medical wearables. 2. Network Level: Enforce end-to-end encryption (TLS/DTLS) for all data in transit. Use mutual authentication (e.g., X.509 certificates) between devices and gateways. 3. Cloud/Data Level: Apply strict Role-Based Access Control (RBAC) to patient records, use data anonymization techniques, and employ AI-driven anomaly detection to identify potential breaches in real-time.
