ATT Wireless network admin: beware of theft

It has been said many times. Security is important in a network, it is equal and more important if it is a wireless network. Someone may be "theft-ing" your connection without you knowing.

SECURITY experts are warning internet users of a new threat to their computer systems, with thieves gaining access to other people's broadband from unsecured wireless networks in homes and businesses.

Known as "leaching", the unusual form of theft involves neighbours and passers-by logging on to a home or business wireless network and surfing the web for free. The consequences can range from slower download speeds to massive bills for unsuspecting network owners.
Market research firm IDC estimates there are more than 200,000 wireless networks operating in homes around Australia, increasing the opportunities for sneak thieves.

Stealing internet access has also become easier. Thieves need only a tiny wireless card for their laptop computer.

"Uni students don't necessarily have broadband at home, so they just go out and find a wireless network to borrow," said Kim Valois, global head of security at Computer Sciences Corporation. "It's not really illegal, it's like leaving the door open and someone coming in and watching your cable TV."
