Wireless Security By The Gallon

prostoalex writes "The next effort to improve wireless security might involve a trip to Home Depot. Force Field Wireless sells buckets of aluminum and copped-laced paint designed to prevent the 802.11 packets from escaping the building, Information Week reports. The article also talks about the Firce Field's pitch to the government in order to improve the homeland security, but the only governments that got interested in anti-Wi-Fi paint were from the Middle East. According to the products page, they also sell the brush sets." Easier than wallpaper, or moving into an old house.

As this "security improvement" only affects computers in specially prepared rooms, WHY THE FUCK use wireless at all? A nice Cat5 is 10times faster than wifi, and even more tempest-proof than a metal painted room.
Not to mention that even to most fancy cable management system will be less work and cost than painting all walls+ceiling (and what about the floor if you arent in the basement?)...

No the special rooms mentioned in the article are the Faraday cage, with which they compare the effect. This is what happens when you skim an article, just looking for something to bitch about. The article clearly states that this paint is intended for entire buildings, for example (from the article):

DefendAir would be an attractive option to protect an RFID-enabled warehouse, he says.

Also

More important, it blocks mobile-phone signals.

Can you imagine the benifit of using it in the outside paint for a movie theater, or resturant. You whouldn't even have to use jammers (which whould bleed into the street and are illegal anyways) to achieve freedom from hearing only one side of someone's conversation.
