Organizations' planning on deploying v2.1 technologies should monitor developments involving new vulnerabilities and threats and additional security control recommendations. As the specification (v2+EDR) or v2+ becomes more widely adopted, it is likely that additional vulnerabilities will be discovered and additional recommendations needed for securing v2.1 technologies effectively. In basic mode of Bluetooth layers, L2CAP (Logical link control & Adaptation Protocol) provides reliable sequenced packets with a payload configurable up to 64kB, with 672 bytes as the minimum mandatory supported size. From the point of view of security issues it is seen that some security modes are secured and some are non secured. Version 2 (actually v2.0 + EDR, enhanced data rate) is also quite ideal in perspective of security that means it supports more security tools (services in operation with 4 security modes) than earlier versions. This version is backward compatible and can easily be connected to transfer data to/from Bluetooth devices of earlier versions (specially of v1.1). Ericsson, IBM, Intel, Nokia, and Toshiba formed the Bluetooth Special Interest Group (SIG), a not-for-profit trade association developed to drive the development of Bluetooth products and serve as the governing body for Bluetooth specifications2. Bluetooth technology was originally conceived by Ericsson in 1994. Bluetooth is a standard and communications (wireless) protocol operates on the unlicensed1 2.4GHz band primarily designed for low power consumption, with a short range (power-class-dependent: 1 meter, 10 meters, 100 meters).
