Network Security is the backbone of digital infrastructure protection.
This pillar maps how networks are designed, defended, monitored, and secured across modern digital systems — from home routers to global internet infrastructure.
This hub covers:
- Network attack surfaces
- Router & modem security
- Firewall architectures
- VPN and encrypted tunnels
- DNS security systems
- Zero Trust networking
- ISP-level security
- Traffic monitoring
- Network segmentation
- Future internet security models
Network Security is not connectivity — it is control, trust, and resilience.
