Wireless infrastructure is the backbone of modern enterprise connectivity, yet it presents the largest attack surface for potential breaches. Configuring a business network requires architectural rigor beyond simple password protection.
Protocol Hardening
Legacy WPA2 standards are susceptible to decryption. Implementing WPA3-Enterprise ensures 192-bit cryptographic strength and individualized data encryption for every connected client, shielding sensitive internal communications from packet sniffing.
Perimeter Isolation
Allowing transient devices onto the primary VLAN creates a vector for lateral movement attacks. A segmented Guest Network policy is essential:
- VLAN Segregation: Logical isolation of visitor traffic from corporate servers.
- Bandwidth Throttling: Prioritizing business-critical operations over guest usage.
- Client Isolation: Preventing connected guest devices from communicating with each other.
Signal Containment
Physical security extends to the radio frequency. Adjusting transmit power (TX power) to prevent signal bleed into public areas minimizes the window of opportunity for “parking lot” attacks and drive-by scanning.
