What concerns should be understood about data communications being sent over wireless networks? Discuss the pros and cons of one method of transmission, such as Wireless Application Protocol (Search the Internet for help in wireless networks). Atleast 300 words.
Web and Data Security What is a Basic Service Set? a. a group of wireless devices served by a single AP b. wireless devices set up as a basic ad-hoc network c. a wireless network that does not use an AP d. multiple APs are set up to provide some overlap
Web and Data Security Another name for a VPN connection is tunnel. True False
Think about an application in which at least two completely different wireless data communications technologies are used simultaneously, to accomplish a single task like making a phone call, for example. This is something that most of us use every day, but we seldom think about it.
1. The OSI reference model is an idealized model that neatly breaks down communications and networks technology into functional layers with sharp well defined interfaces between each layer. True False 2. An insider attack can occur from within the boundaries of a VPN, Router or Firewall. True False 3. Implementing both a router and firewall for a PC is wasteful and provides no benefit for security. True False 4. Symmetric encryption uses how many unique keys to encrypt and decrypt...
1) What is the protocol developed for the wireless network communications? Explain. A) Wireless Encryption Protocol (WEP) B) Wireless Application Protocol (WAP) C) Wired Equivalent Privacy (WEP) D) Wireless Session Protocol (WSP) 2) Consider 802.11 shared key authentication. Which of the following statements is false? Explain. A) If a device with the key is lost then the security for the entire WLAN is compromised. B) 802.1X requires shared key authentication. C) Real users and attackers with a shared WEP key...
1. (a) Explain the terms “data encryption, authentication, and message integrity,” often used in the networks security literature. (3 Points) (b) Lorenzo likes to send to his close friend Art a secret market data related to their business using public key cryptography (RSA algorithm). He chooses two prime numbers 7 and 11, and a public key e = 13 to encrypt the data. Art uses d=37 to decrypt the data. Indicate why (e, 77) and (d, 77) are valid public...
Social security numbers are often used as identification. if one takes a sample of social security number, what type of data would one have? (be careful. This is a trick question.)
2. (20 Points) Bayesian networks are used on the Web sites of high-technology manufactures to allow customers to quick diagnose problems with products. An oversimplified example is presented here. A printer manufacturer obtained the following probabilities from a database of test results. Printer failures are associated with three types of problems: hardware, software, and other (such as connecters), with probabilities 0.1, 0.6, and 0.3, respectively. The probability of a printer failure given a hardware problem is 0.9, given a software...
1. (a) SNMP management is the most widely used network management system for enterprise networks. Briefly discuss the characteristics that allow it to have this status. (b) It took a considerable amount of time for the SNMP security subsystem to be developed. Briefly discuss the controversies encountered during the development stages. What do you think could have been done differently? (c) Describe a specific example of how the network operations center uses remote monitoring to efficiently manage networks Help in...
