Critically examine how massive IoT density and private 5G networks expand the cybersecurity threat landscape. What measures should CERT-In adopt to protect this critical infrastructure? – GKToday

Massive IoT deployment and private 5G networks shift cyber risk from isolated device faults to large-scale, real-time disruption.

Expanded threat landscape Huge attack surface: Billions of remotely reachable devices create countless entry points.

Weak device security: Default passwords, poor encryption, insecure updates and limited hardware protections leave many IoT devices exposed.

Cyber-physical impact: Private 5G connects sensors, machines and control systems, so breaches can alter operations, not just steal data.

CERT-In measures Issue sector-specific, real-time threat intelligence and attack signatures for telecom, manufacturing, health and smart-city networks.
