Wireless security is a big concern for many people, and quite rightly so. I myself have sat in my top floor flat at home and merrily joined up to 3 different wireless networks in the area, all without any password required. WEP security has been often attacked for being easily cracked (some hackers say about one hour is all it takes) and a number of security professionals are recommending that people just donít use wireless at all. This seems like a shame, given that the technology is so convenient.

Itís nice to see Meru Networks, a wireless infrastructure specialist, developing security software that can jam radio signals from rogue access points and scramble genuine signals, thus protecting wireless networks at the RF signal level.

The companyís Security Services Module, a software module that works in combination with its range of wireless LAN products, notably its access points and radio switches, is expected to be shipping in the second quarter of the year.

Meru (Sunnyvale, Calif.) says the module, which uses its patent-pending AirShield technology, uses advanced micro-scanning, radio scrambling and transmission jamming to ensure military-grade, radio frequency security for any enterprise.
