IoT Security
IoT security는 연결된 디바이스와 데이터를 사이버 위협으로부터 보호하여 디바이스-클라우드 생태계 전반에 걸쳐 기밀성, 무결성 및 가용성을 보존합니다.
IoT security는 디바이스 하드웨어 및 펌웨어, 보안 통신, 데이터 보호, 인증, 접근 제어 및 백엔드 방어를 포괄하는 광범위하고 다층적인 조치 세트를 포함합니다. 여기에는 안전한 디바이스 설계, 위협 모니터링, 사고 대응 및 안전한 업데이트 메커니즘이 포함되어 방대한 디바이스 수, 다양한 생태계 및 IT/OT 융합 환경에서의 위험을 완화합니다.

❓ 자주 묻는 질문
What are the main challenges in IoT security?
Device heterogeneity, scale, resource constraints, insecure defaults, weak authentication, insecure firmware updates, supply-chain risk, privacy concerns, and IT/OT integration challenges.
How can organizations implement IoT security?
Adopt defense-in-depth: secure boot, hardware roots of trust, strong device identity, encrypted channels (TLS/mTLS), authenticated updates, robust device management, continuous monitoring, and incident response.
What role do standards play in IoT security?
Standards from IEEE, NIST, IEC 62443, and ISO/IEC guidance help establish baseline controls, interoperability, and certification programs.
How is data protected in transit and at rest in IoT?
Encrypt data in transit with authenticated protocols (TLS/mTLS) and at rest with strong key management and, where possible, hardware-backed encryption.
What about device lifecycle and updates?
Secure provisioning, signed firmware, verified updates, rollback capabilities, and proper decommissioning procedures.
How is trust established in IoT ecosystems?
Mutual authentication, device attestation, secure key management, and supply-chain assurance across devices, gateways, and cloud services.
