Sonicwall Wireless Firewalling - SonicWALL SonicPoint-Ne Getting Started Manual

SonicWALL Wireless Firewalling

When a wireless device uses an access point to communicate
with a device on another subnet or on a completely different
network, traffic between the devices is forced to traverse the
network gateway. This traversal enables Unified Threat
Management (UTM) services to be enforced at the gateway.
Standard practice for wireless firewalling (where one wireless
client is communicating with another) bypasses many of the
critical UTM security services. The illustration below shows the
standard practice for wireless firewalling.

Many security products on the market share this potential
vulnerability when two users connected by a common hub or
wireless access point wish to exchange data.

SonicWALL addresses this security shortcoming by managing
the SonicPoint access points from the UTM appliance. This
allows complete control of the wireless space, including zone
enforcement of security services and complete firewalling
capabilities, as shown in the illustration below.
