Wireless network security includes typical network-layer security controls applied to wireless (or WiFi) networks. Wireless network security is a serious issue for today's mobile workplace. Administrators face an ever-growing need to protect critical company resources from attacks. When employees access private corporate data over a wireless network, the data may be compromised by unauthorized viewers if the user is not shielding the connection from outsiders (e.g., via password-protected access).
By securing the access layer of a wireless network with an SSL VPN appliance, administrators can remove the burden of managing yet another security mechanism such as WEP (Wired Equivalent Privacy) by securing all user traffic both on the wired and wireless network.
