Wireless Network Security

Subject : it-skills
Instructions:
  • Answer 38 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A checksum based on the contents of the text.






2. A 1999 amendment that added two higher speeds (5.5 Mbps and 11 Mbps).






3. Storing information from a device on the network so if a user roams away from a wireless access point and later returns - he doesn't need to re-enter all his credentials.






4. The second generation of Wi-Fi Protected Access (WPA) security.






5. A 1999 standard with a maximum rated speed of 54 Mbps using the 5-Ghz spectrum.






6. The 2004 wireless security standard that addresses the two main weaknesses of wireless networks; encryption and authentication.






7. Text that is used in shared key authentication to authenticate a device.






8. An organization that sets standards for computer networking and wireless communications.






9. A server whose only job is to verify the authentication of devices.






10. Associating with a new access point.






11. An authentication protocol that uses a passphrase to generate the encryption key and must be created and entered into both the access point and all wireless devices prior to the devices communicating.






12. A 24-bit value that changes each time a packet is encrypted using Wired Equivalent Privacy (WEP).






13. An encryption technology that replaces the Wired Equivalent Privacy (WEP) protocol.






14. A frame that carries information about the data rates that the device can support along with the service set identifier (SSID) of the network it wants to join.






15. Movement between cells of a wireless local area network.






16. A consortium of wireless equipment manufacturers and software providers to promote wireless network technology.






17. A checksum based on the contents of the text - used in WEP encryption.






18. An optional Wired Encryption Privacy (WEP) authentication that uses challenge text for authentication.






19. The encryption mechanism of the IEEE 802.11 standard - considered to provide only low security.






20. The first version of the security standards set by the Wi-Fi Alliance.






21. An access point with limited functionality. (It does not provide authentication or encryption.)






22. A proposed standard for faster wireless LANs projected to be ratified in 2009.






23. Encrypted text.






24. An attack that attempts to determine the keystream by analyzing two packets that were created from the same initialization vector (IV).






25. A series of 1s and 0s equal in length to the text to be encrypted with Wired Equivalent Privacy (WEP) plus the integrity check value (IV).






26. A device that can monitor the airwaves for traffic.






27. Acipher algorithm used in Wired Encryption Privacy (WEP) that takes one character and replaces it with another.






28. Scanning for a wireless device that listens for a beacon frame for a set period of time.






29. Two packets derived from the same initialization vector (IV).






30. A standard originally developed for wired networks that provides a greater degree of security for wireless networks by implementing port-based authentication.






31. Unencrypted text.






32. An advanced security encryption protocol used in the Wi-Fi Protected Access 2 (WPA-2) standard.






33. The default method of authentication used by the IEEE 802.11 standard.






34. A protocol designed to prevent an attacker from capturing - altering - and resending data packets.






35. The network name for the wireless network that can be any alphanumeric string from 2 to 32 characters.






36. A standard formally ratified in 2003 for wireless LAN transmissions of devices transmitting at 54 Mbps.






37. A switch that contains authentication and encryption for wireless networks.






38. A technology that allows a device to become authenticated to an access point before moving into its range.
