4.0 BLUETOOTH SECURITY STANDARDS
4.1 Wireless Security
One of the major problems with wireless technologies is their security. Non-wireless networking technologies require to tap into the actual line to see the flow of bits, however, with wireless all you have to do is be in the range of the transmitting device. This allows anyone with a receiver to pick up the bits “flapping in the breeze”. This causes security to be one of the main areas of concentration for all wireless technologies. 4.2 Four Essentials of Security
Security is made up of four essential parts: authentication, data integrity, non repudiation, and confidentiality. Authentication involves ensuring that transmissions and messages, and their originators, are authentic and a recipient is eligible to receive specific categories of information.[6] Data

The device we will be looking at s a Local Area Network Access Point. It provides access to a Local Area Network through Bluetooth wireless technology. This is a usage scenario in which a Bluetooth device may need actual security, as a sensitive and confidential data may be passed between a laptop and a computer on the network. Bluetooth is capable of setting its security to various levels. In this example the device’s security is as high as possible, which is the real test for measuring Bluetooth security.
In this test the security mode will be set at level three, which ensures that all connections toward the LAN access point are authenticated and encrypted. Once again, the importance of pairing in a secure area remains the same. If an eavesdropper has all the information from the pairing, then the eavesdropper will be able to break the Bluetooth security. This is most definitely the weakest part of Bluetooth security. It is possible to make the link keys harder to compute by using a large passkey, this offers a small amount of added protection, but by no means is a
C1 then conducts a coin to randomize the order of which the two key bits are send to C2. C2 decrypts the two bits and evaluates which one is greater and informs C1. C1 then decides whether the condition is satisfied. During the execution of this protocol no information regarding the value of the two integers being compared is ever revealed to C2.
6. True or False: NetStumbler can check for wireless networks and their signal strength, review which channels are being used, and then compare competing networks to monitor interference. 7. Wireless networks were identified by drawing
7.7.1 Data Owners 1. One whose going to access files, one who owns file, who requires his data to be secure. 2. Data owners are responsible for encrypting the data by generating private key. MMCOE, Department of Computer Engineering, 2015-2016 26 Regeneration of code based cloud storage 3.
Wifi WPS: It stands for “Wi-Fi Protected Setup” and provides simplified mechanisms to configure secure wireless
• ICMP; is one of the main rules of the internet protocol suite. It is used by system devices, like router, to send error messages showing, for example, that a demanded service is not offered or that a crowd or router could not be touched. • DHCP; Dynamic host configuration protocol is a customer server rules that repeatedly delivers an internet rules (IP) address and other linked arrangement information such as the subnet mask and avoidance entry. • Bluetooth; Bluetooth is a wireless communication technology that lets people to usefully connect their plans with other policies “and “the character of the technology is developing to not only allow devices to talk with one another, but actually allow the all-in-one communication between devices, native requests and the cloud.” •
51. Which is used to preserve the reliability of a document or a message. a) Message digest b) Encryption of message c) Encrypted message d) None of the mentioned Answer: c 52.

With Apple TV, Apple wants to connect a customer’s iPhone and their other equipment in their house, but maintain the sensitive information used to only that particular user to not be hacked. Apple tries to stray potential hackers away from the Apple TV through a two-step process to make iCloud accounts credible by having the Apple TV and the device that’s being used send and receive temporary public keys via iCloud. When the items are on a LAN, the temporary keys will get a connection through the use of Station-to-Station protocol and the other per-session keys, to decode to establish that everything is similar among all platforms that are being used. Over the same connection, the customer’s device will exchange the public-private key pairs to Apple TV to secure the relationship that the Apple TV and other iOS
In 1972, G.S. Graham and P.J. Denning, developed the Graham-Denning Model that shows how subjects and objects should be securely managed to include creation and deletion. It also addresses how to assign specific access rights. The model is set up based on subject, object, and rules that tie in both. The Graham-Denning model resolves the security questions related to defining a set of specific rights on “how particular subjects can execute security functions on an object.” (Pfleeger & Pfleeger, 2003)
To reduce the risk, companies or schools should use multi authentication. 8. Natural disaster Can result in loss of important and confidential information of businesses Back-up the systems on regular basis to avoid losing all of the data. 9. Unauthorized user gain the access to your workstation This risk could be loss of your personal information and data on your computer Should monitor the access to your workplace.
From the first e-Activity, analyze the industry researched for each security model would be most applicable, and explain why you believe that to be the case. Identify the security models from your findings. Information is priceless in the modern world of business, and it’s interesting to note that different security models are suitable for particular industries. Information security models often restrict access to stored information by unauthorized person to reduce disclosure, modification, disruption, destruction use, perusal, and inspection of crucial information. Role-based access control security model is more suitable for a highly specialized industry like the electronic equipment industry since it allows a business to exploit role mining to realize high-quality roles in the current access permissions.
Cisco, a leading networking giant and a pioneer in the field, predicts that by 2020, there will be up to 50 billion connected devices. That is a very large number. As intelligence, data storage and analysis will move towards the edge , many devices will be located in locations of low security, making them vulnerable to
Cyber threats continue to plague governments and businesses around the world. Cyberwarfare is Internet-based conflict involving politically motivated attacks on information and information systems. Normally there are two purposes of Cyberwarfare, espionage or sabotage. Cyberwarfare attacks can disable official websites and networks, disrupt or disable essential services, steal or alter classified data, and cripple financial systems. Cyber operations can also aide military operations, such as intelligence gathering and information warfare.
Most users know that this can uncover the iPhone or iPad with an impression, but it can let users log in to programs
For example, criminals have found ways to attack unsecured laptops and smartphones to gain access into conversations and data related to business operations such as deals, trade secrets and even accounts and the associated customer databases. According to the Cyber Threat to UK business 2016/2017 Report “It is highly likely that connected devices in industry are already targeted and that incidents are more common than are currently reported or that have been detected. In the past, most industrial systems were securely locked down and not accessible to the outside world, but as more industrial systems become connected, the risk of an attack greatly increases”.
