Episode 109: Securing Wireless Networks (Part 1) (Domain 4)

Wireless networks offer convenience, but they also expand the attack surface by broadcasting connectivity beyond physical boundaries, making them inherently riskier than wired alternatives. In this episode, we focus on securing wireless environments beginning with proper access point placement, signal strength tuning, and site surveys that help prevent signal bleed and rogue AP exposure. We also cover basic configurations like disabling SSID broadcast (in select cases), using WPA3 encryption, and implementing strong authentication methods such as 802.1X with RADIUS. Physical security plays a role as well, including locked enclosures and controlled installation areas to prevent unauthorized tampering. Monitoring for unauthorized connections, MAC spoofing attempts, or signal interference is essential, especially in high-density or regulated environments. Wireless security must balance performance with protection, and that means understanding the physics of radio signals just as much as the logic of encryption.
