Objectives of security:
So security is most important part of any system. To protects user’s data from theft or lost; so Bluetooth claims some security objectives like access control based on link layer. Ensures that device authentication is being secret, only authorized user can access it. Confidentially about exchanging information cannot be disclosed publically and integrity detect the modified data and ensures that data may not be changed/delete or modified.
Over view of Bluetooth Security:
Symmetric encryption process is use in Bluetooth; therefore decryption is done on same process, by using same key during encryption and decryption and the exchange of secret key must be done in advance.
Four entities are used to maintain the security on link layer is:
• The address of device is using 48bits BD_ADDR.
• It can use 128bits authentication link key.
• The encryption key is gained from the authentication key so every time new secret key is 8-128Bits is being generated due to activation of encryption on each time.
• Every transaction of each device, pseudo-random number is generated which is of 128Bits.
Checking of integrity:
Channel access code may check the packets for errors or wrong delivery, by HEC in header and CRC in data payload it can be done in three steps. Where, the packets may have, shortened access code in first step, in second step it has access code and packet header, while in last third step it has access code, packet header and pay load. However, every packet begins with data access code it is used for synchronization, DC offset compensation and identification so it can examine in exchanged all packets on physical channel. Header error check is an 8-bit code which can check the header integrity and the payload...

...device or moving out of range.
Solutions:
There is no such guarantee to stop these attacks. Whereas, installation of some fire walls and antivirus may prevent these attacks which can be schedule updated. It can prevent device for interference of any unwanted files which can cause threat like worm, Trojan, virus etc that can cause there security issues. Do not give access to unwanted files. So it is important to look after our system devices time to time. Many devices like printer, mobiles also CCTv cameras are based on this technology so it can cause big security issues.
Conclusion:
In the nutshell every coin has two sides, as like other systems no matter Bluetooth may also have some security issues. But it can introduce this world a new wireless technology and personal area network as well as many devices can communicate with each other through Bluetooth.
In this section we investigate attacks and threats to our primary devices. These attacks and threats are built off of the vulnerabilities the previous section and help to determine which security controls would be most valuable against future attacks.
Multiplexing will gather the data from the source host and give that data some header information. This data will be created into segments by demultiplexing and then be sent to the 3rd layer (Network layer). So to summarize multiplexing will gather data and give it header information and demultiplexing will create segments and sent them to the network layer. Now with flow control that will relate with multiplexing, mainly because it can take multiple data streams and combine them into one shared stream, making that a form of data flow control. Now as far as error checking that will relate to the frames of the data. The logical link control will use a frame check sequence (FCS) to check the frame to see if there is any problems with it. If it detects an error during the frame check sequence then the frame will be discarded and the data will be passed on to the network layer. With this all being said this will mainly be used in the OSI model since the logical link control is the sub-layer for the data link layer. (The other sub layer being MAC) Without the logical link control or 802.2 then the data link layer wouldn’t function
This is the circuit diagram for the Bluetooth module that we are planning to use. What we have to do for Bluetooth circuit is connect pin 8 from the analog switch into the transmitter (TX). The next step is to connect pin 17 from the encoder into the receiver (RX). This will send the outputs from the switch and the encoder into the Bluetooth circuit and from where we can have it send out a notification to a cellular phone or anything that can receive Bluetooth messages.
The ability to record information which is relevant to a product and service will help ensure an exceptional customer experience. The ability to access this information anywhere in the world is also key to supporting the customer. (http://www.cio.com/archive/ec_blueprint.html) Wireless devices such as laptops,
Bose Corporation is global and this enhances the private company in a big way. Some of the new devices Bose implemented are: New Bose QuietComfort 20 and 20i, Acoustic Noise cancelling and New Bose SoundLink Mini Bluetooth speaker all available July 11, 2013 (Business Wire, 2013). The Bluetooth is owned by Bluetooth SIG, Inc. and license under Bose Corporation. Since the corporation is global, this will give the company more of an opportunity to stay relevant to the business.
As we progress deeper into the digital era, we rely more and more on our electronic devices. Over the last decade, almost everyone who lives in a developed nation owns a cellphone and they are becoming an integral part of our life.
Asymmetric Key Encryption methods are DSA, Diffie Hellman, RSA, Elliptic Curve and DSA. Asymmetric Encryption

After this report, BT’s senior management truly realized this that now if they will not do anything they are surely going to lose market soon. This led to the idea of setting up of various units in some areas of world like US , Japan etc. to know their customers closely and will help in bringing outside ideas inside the organization. This idea really worked and BT came to know what exactly his customers want and what are his strengths and weaknesses. Due to this, BT started realizing that to maintain its position in such hard competition, it needs to focus on the quality of its products and to continue offering its products and services at low cost because that time BT’s competitors already introduced substitute products in the market and customers were thinking of shifting to other companies offering better technologies.
“ Prevention is better than cure ”, if computer users are aware of Malware attacks, they may prevent those attacks . So, in this research paper i am going to focus on Malware and Protecting Against Malware.
The world has gone through a lot of changed as time passes by. With advancements in the technological field people are can communicate with ones from around the world without having to even lift a finger. To make things more efficient and more cost saving industries have made technology wireless. Wireless technology gives people the chance to get up from their stationary computer, or cord phone and able to freely move without restrictions. The IT, or Information Technology has become a standard and very critical part of today’s society. Wireless technology came from the basic just cellular usage to sensors in the medical field. Wires are now a thing of the past in today’s world with forever revitalizing technology.

This paper is going to discuss wireless security from a broad view where I will go into why exactly wireless security is so important especially today as the ways in which we are communicating is changing dramatically. From there I will discuss the multiple wireless securities that are available to give a better understanding of the options given. Then I will go into why exactly not protecting your wireless can be so dangerous with some descriptions on the most dangerous wireless attacks out there today. Finally I will then discuss how we can better prepare for these types of attacks with a synopsis on several effective security methods that will help to ensure data is securely passed and kept hidden.
...ntial information from a user. Luckily, there are reliable ways of defending against them. The most reliable way is to install strong security software that has the capacity to defend against the multifaceted forms of threats. Avoiding P2P file sharing sites and scanning email attachments before downloading them are also a surefire way of protecting a computer against malware threats. Basic acts like using an updated browser and allowing Windows updates to install and update themselves are also necessary to keep a machine safe. Furthermore, checking validity of individual website addresses and installing authenticated software can also help a computer user remain safe from potential data theft and possible damage of useful programs. It may also pay good dividends to backup files. In case of a lethal malware attack, backed-up files can always be recovered easily.
