Deputies and community service volunteers are implementing a device that finds open wireless networks. The device, which is about the size of a key chain and costs about $80, lists the names of the networks and signal strength, allowing the sheriff's office to pinpoint the origin of the network.
An unsecured network broadcasts a signal, inviting any computers within range to log on. Once a computer is logged onto the network, the user can access information stored on other computers also using the network.
"People have these [networks] for ease," said Lt. Alan Stanton, DCSO lieutenant of community relations and training. "Anyone with basic computer skills can access personal information and sensitive files."
Once the sheriff's office locates an unsecured network, either a deputy or a community service volunteer will contact the resident or business that owns the network and provide information on how to secure it.
Open wireless networks mostly provide the potential for identity theft and fraud, but there is also a chance of someone logging onto a network and using the network owner's Internet protocol address to commit crimes, such as trading child pornography, Stanton said.
Most major wireless routers provide basic security without the user making any changes to the network; however, anyone with a manual to the router will have access to passwords if they are not changed.
"We have not seen a large problem, but the potential is there. We want to stop the problem before it becomes a problem," Stanton said. "There are no other agencies in the state of Colorado that we are aware of that are doing this type of program."
