  Wireless security protocols

  Types of modem

  Radio frequencies for Wi-Fi

  Brands of Wi-Fi

 2. WEP offers relatively poor security and is no longer supported by the Wi-Fi Alliance.

  FALSE

  TRUE

 3. What does WPA stand for?

  Wi-Fi Protected Access

  Wi-Fi Purchase Accreditation

  Wireless Protocol Agreement

  Web Personal Access

 4. WPA generally uses a ___ pre-shared key.

  512-bit

  128-bit

  64-bit

  256-bit

 5. WPA was succeeded by WPA2. WPA2 offers better security as it supports ______ ______ ______.

  Advanced Encryption Standard (AES)

  Improved Security Access (ISA)

  Limited Portal Selection (LPS)

  Secure Wi-Fi Encoding (SWE)

 6. An advantage of WPA2 is that it has no known security flaw.

  TRUE

  FALSE

 7. Routers usually broadcast the 'name' of the Wi-Fi network by default (e.g. 'Guest Wi-Fi'). The technical term for the name of a network is the …

  wireless identification flag (WIF)

  wireless signal marker (WSM)

  service set identifier (SSID)

  router digital label device (RDLD)

 8. Most routers allow this broadcast to be disabled. Why would doing this improve the security of the network?

  It will improve the encryption of the Wi-Fi password

  It activates a virtual firewall that monitors network traffic

  It will be impossible for someone not already connected to the WLAN to join the network

  A hacker would need to find out both the network 'name' and the password to access the WLAN

 9. A MAC (Media Access Control) address whitelist is a list of approved MAC addresses that are allowed to connect to a network.

  TRUE

  FALSE

 10. Why would a whitelist provide little protection against a sophisticated Wi-Fi hacker?

  The MAC address contains the Wi-Fi password

  It is straightforward to add an address to the router's whitelist

  MAC addresses can be spoofed

  MAC addresses are easy to guess
