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.
