Q: What are the data security and privacy considerations for IoT deployments?
Answer
IoT security considerations: (1) Encryption: TLS 1.2+ for all data in transit. At-rest encryption for local storage (AES-256). (2) Authentication: certificate-based mutual TLS preferred; pre-shared keys (PSK) for resource-constrained devices. (3) Device identity: use hardware root of trust (TPM eFuse ARM TrustZone). (4) Network segmentation: IoT devices on a separate VLAN from corporate IT. (5) Firmware integrity: verified boot (Secure Boot) ensures only signed firmware runs. (6) API security: OAuth 2.0 + JWT tokens for cloud API access. (7) Data minimization: transmit only necessary data. (8) Privacy: encrypt PII at the edge before cloud storage. (9) Compliance: GDPR for EU devices; CCPA for California. (10) End-of-life: implement secure erase (cryptographic erase by deleting key) before device disposal. Use a security information and event management (SIEM) system for monitoring.
