Wireless Security Landscape
Wireless networks extend your attack surface beyond physical walls. Attackers can target your network from parking lots, neighboring buildings, or public spaces.
The Wireless Risk
- Extended attack surface - radio waves don't stop at walls
- Rogue access points - backdoors into your network
- Client attacks - evil twin, credential harvesting
Protocol Security Evolution
WiFi Security Standards
WEP
Broken - crackable in minutes
WPA/WPA2 PSK
Offline dictionary attacks
WPA2 Enterprise
802.1X, RADIUS auth
WPA3
SAE - resistant to offline
Wireless Attack Methodology
Common Attack Flow
Reconnaissance
Passive scanning, SSID discovery, client enumeration
Handshake Capture
Deauth attack, capture 4-way handshake
Credential Attack
Dictionary attack, GPU cracking with hashcat
Evil Twin
Rogue AP, credential harvesting, MITM
WPA2 Enterprise
For enterprise environments, WPA2 Enterprise with EAP-TLS (certificate-based) provides the strongest protection against credential attacks.
Security Hardening
Wireless Security Controls
Protocol Security
Enterprise Auth
Network Design
Monitoring
Quick Win
Disable WPS immediately - it's vulnerable to brute force and provides an easy bypass of your WiFi password.
Conclusion
Wireless security requires proper protocol selection, network segmentation, and continuous monitoring. Regular penetration testing validates your wireless defenses against evolving attack techniques.
