Where's Your End-Point?

Modern wireless networks are fielded with security without thought to where the security ends. Typical 802.11 access points secure the 300-foot or so space between the station and the Access Point (AP). This is fine for a Home network with an AP or router only a few feet away, but inadequate for an enterprise or corporate network where the larger wired or wireless gap to the data center can span floors in a building, or between facilities. If WiMAX or long-haul bridges and repeaters are used (as in Mesh Networks), the distance can be many miles/km. This leaves a huge backdoor that can be sniffed or tapped. This weakness has now made headlines and the risks have been shown to directly translate to major financial cost in the billions due from theft and privacy loss.

To be really secure, encryption should originate from the Datacenter, not each AP. This way, the AP is just a passthrough and can be set to open mode and still pass the encrypted traffic end-to-end, regardless of distance. The WirelessWall software from TLC-Chamonix, LLC is both the cheapest solution and the most secure, since it makes any existing wireless infrastructure sniffer-proof with no new capital equipment.
