The link manager PROTOCOL is responsible for link set-up between Bluetooth devices. This INCLUDES setting up of SECURITY functions like authentication and encryption by generating, exchanging and checking of link and encryption keys and the control and negotiation of baseband packet sizes. Furthermore it controls the power modes and DUTY cycles of the Bluetooth radio device, and the CONNECTION states of a Bluetooth unit in a piconet.

Discovery SERVICES are CRUCIAL part of the Bluetooth framework. These services provide the basis for all the USAGE models. Using SDP, device information, services and the characteristics of the services can be queried and after that, a connection between two or more Bluetooth DEVICES can be ESTABLISHED. SDP is defined in the Service Discovery Protocol specification.

IrOBEX (shortly OBEX) is a session protocol developed by the INFRARED Data Association (IrDA) to exchange objects in a simple and spontaneous manner. OBEX, which provides the same BASIC functionality as HTTP but in a much lighter fashion, uses a client-server model and is independent of the transport mechanism and transport API, provided it REALIZES a reliable transport base. Along with the protocol itself, the "grammar" for OBEX conversations between devices, OBEX also provides a model for representing objects and operations. In ADDITION, the OBEX protocol defines a folder-listing object, which is used to browse the contents of folders on remote device. In the first phase, RFCOMM is used as sole transport layer for OBEX.

Bluetooth can be used to wirelessly SYNCHRONIZE and transfer DATA among devices. Bluetooth can be thought of as a cable replacement technology. Typical uses include automatically synchronizing contact and calendar information among desktop, notebook and palmtop computers without connecting CABLES. Bluetooth can also be used to access a network or the Internet with a notebook computer by connecting wirelessly to a cellular phone.

Bluetooth is extremely secure in that it EMPLOYS several layers of data encryption and user authentication measures. Bluetooth devices use a combination of the PERSONAL Identification NUMBER (PIN) and a Bluetooth address to identify other Bluetooth devices. Data encryption (i.e., 128-bit) can be used to further ENHANCE the degree of Bluetooth security. The transmission scheme (FHSS) provides another level of security in itself. Instead of transmitting over one frequency within the 2.4 GHz band, Bluetooth radios use a fast frequency-hopping spread spectrum (FHSS) technique, allowing only synchronized receivers to ACCESS the transmitted data.

FREQUENCY-Hopping Spread-Spectrum (FHSS) is a spread spectrum modulation scheme that uses a narrowband carrier that changes frequency in a pattern known to both transmitter and receiver. Properly SYNCHRONIZED, they maintain a single logical channel. To an unintended receiver, FHSS appears as short-duration impulse noise. More simply, the data is broken down into packets and transmitted to the receiver of other devices over numerous "hop frequencies" (79 total) in a pseudo random pattern. Only transmitters and receivers that are synchronized on the same hop frequency pattern will have ACCESS to the transmitted data. The transmitter switches hop frequencies 1,600 times per second to assure a high DEGREE of data security.

A fingerprint is an impression of the friction ridges on all parts of the finger. A friction ridge is a raised PORTION of the epidermis on the palmer (palm) or digits i.e. fingers and toes or plantar or sole skin, consisting of one or more connected ridge units of friction ridge skin. This is also KNOWN as Epidermal Ridges which is ORIGINATED by the underlying interface between the DERMAL papillae of the dermis and the interpapillary (RETE) pegs of the epidermis.

Well sir, an Authentication factor is a piece of information and process used to authenticate or VERIFY the IDENTITY of a person or other entity requesting access under security constraints. In other word, it is a process of PROVING the identity of a computer or computer user. For users, it generally INVOLVES a user name and password. Computers usually PASS a code that identifies that they are part of a network.

Always remember that PING does not use any port. As PING is based upon LAYER 3 protocol, it NEVER uses any computer port. A simple VARIATION of the question could be: Does PING use UDP? Or Does PING use TCP? Again remember that UDP and TCP are layer 4 protocols and PING has NOTHING to do with them.

The question can also be in two parts, in which case, candidates WITHOUT knowledge of CSRF would get lost. If asked combined, candidates can guess that cross site request FORGERY is something that relates to malicious scripting with phishing INTENTIONS. The question may also be framed as "what is cross site request". In this case, candidates cannot even guess that it is something malicious as the word 'forgery' is not there.

Again, this QUESTION is EMPLOYED to ASSESS the skills and networking background of CANDIDATES. "I don't have a network at home but I have handled NETWORKS at so and so places" is better than saying "sorry, I don't have a network at home". The latter would send out a signal that the candidate never had exposure to networks.

Answer is simple. One would always sign USING their key so the PUBLIC key is used for encryption. Most of the CANDIDATES tend to name public key for both signing and encryption. They MISS out the point that public key encryption also includes a private key.

The candidate may start EXPLAINING what is data encryption, how s/he would encrypt the data and then compress it for transmission. However, the actual ANSWER would be to EXPLAIN how to compress and then talk about encryption. ENCRYPTING compressed data OFTEN leads to loss of data.
