Breakthrough in Security Protection for Industrial 5G Routers
Core Risk Cognition Breakthrough: Clarify that the AirSnitch vulnerability (Wi-Fi protocol flaw) has no impact on industrial 5G routers, and shift the security focus to the unique risks of cellular networks, such as SIM card hijacking and fake base stations, avoiding blind defense and improving protection efficiency.
Cellular Network Layer Hardening Breakthrough: Adopt “dedicated APN + SIM PIN + signal control” to build a first-line defense for cellular networks. Enterprise-specific APNs achieve operator-level network isolation, SIM PINs prevent SIM card theft and cloning, and disabling weak-signal switching avoids being trapped by fake base stations, filling the security gap of 5G public network transmission.
Industrial-Grade Isolation and Encryption Breakthrough: Combine “LAN/WAN physical isolation + VLAN partitioning + mandatory VPN encryption” to meet the high-security requirements of industrial scenarios. All industrial protocol traffic is forced to pass through VPN tunnels, and the firewall default deny policy is implemented, which not only prevents cross-network attacks but also avoids plaintext leakage and tampering of industrial control protocols.
Operational Security Breakthrough: Integrate firmware maintenance, log audit, and remote access control to form a full-cycle security management system. By closing high-risk services, setting up abnormal alerts, and restricting remote access channels, it solves the problem of security loopholes caused by improper operation and maintenance in industrial scenarios.
