What is WiFi Security?

Wireless networks have two distinct security challenges in comparison with wired networks.

  1.  Data is transmitted over-the-air, meaning no physical barriers exist. Cybercriminals can capture or inject traffic into the network without being on-premise.

  2.  Mobile devices are often used on home and public WiFi hotspots in addition to enterprise networks. Hackers can access mobile devices in these less secure environments and install malicious code that can be exploited when the device subsequently connects to the enterprise network.

Like wired networks, essential parts of protecting wireless networks are firewalls, intrusion protection systems, and VPNs. However, this blog focuses on the security mechanisms defined to protect WiFi networks from attack.
