Security
Today's wireless world means that data is being sent, among us, invisibly from device to device, country to country, person to person. This data, in the form of e-mails, photos, contacts and addresses are precious and private to each of us. This private information, no longer making its way along wires in plain sight, needs to be sent securely to its intended recipient without interception. Wireless standards the world over are evolving and have various formats for dealing with the security issues of its users. Bluetooth wireless technology is no exception.
Bluetooth wireless technology has, from its inception, put great emphasis on wireless security so that users of this global standard can feel secure while making their connections. The Bluetooth Special Interest Group (SIG), made up of over 4000 member manufacturers, has a Bluetooth security experts group made up of engineers from its panies who provide critical security information and feedback that is taken into account
as the Bluetooth wireless specification evolves.
Product developers that use Bluetooth wireless technology in their products have several options for implementing security. There are three modes of security for Bluetooth access
between two devices.
        Security Mode 1: non-secure
        Security Mode 2: service level enforced security
        Security Mode 3: link level enforced security
The manufacturer of each product determines these security modes. Devices and services also have different security levels. For devices, there are two levels: "trusted device" and "untrusted device." A trusted device, having been paired with one's other device, has unrestricted access to all services. With regard to services, th
