Given a scenario, install and configure wireless security settings.
Description: The ability to properly configure an AP is an important skill for any wireless network professional as well as, to a lesser degree, for users. In this project, you use an online emulator from TRENDnet to configure an AP. Answer the following using citations and references for each question.
Submit each question and your responses including any applicable screenshots.
1. Use your web browser to go to www.trendnet.com/emulators/Tew-818dru_v1/login.htm. (The location of content on the Internet may change without warning; if you are no longer able to access the program through this URL, use a search engine and search for "Trendnet Emulators.")
2. The emulated login screen will appear. Click login without entering a username or password. 3. An emulated Setup screen is displayed, showing what a user would see when configuring an actual TRENDnet. 4. Be sure that the BASIC tab is selected in the left pane. Note the simulated Network Status information. 5. Click wireless in the left pane and read the information displayed. 6. Under Broadcast Network Name (SSId), click the down arrow next to enabled. What other option is available? Would it be an advantage to change this setting? Why or why not?
7. Under Frequency (Channel), note that the default is Auto. What does this mean?
8. Click the down arrow on Auto. When would you want to change the channel on which the wireless signal is broadcast?
9. Under Channel Bandwidth, click the down arrow on 20 MHz. What is the other option? Why would you choose this option? What are the advantages and disadvantages of changing the channel bandwidth?
10. Under Security Policy is a single configuration option, Security Mode. Note the default setting. Is this a good option default option? What does wPA2-PSk mean?
11. Click the down arrow on wPA2-PSk. What are the other options? What do they mean?
12. Under wPA, note the option wPA encryption. Click the down arrow on AeS. What are the other options available and what do they mean?
13. Under wPA passphrase, note the length of the default passphrase. Is that sufficient?
14. In the left pane, click Guest Network. A guest network allows you to have an additional open network for occasional guests that does not affect the main wireless network. How could this be an advantage?
15. Note the option under Internet Access Only. When would you select this option? 16. Note the option under wireless Client Isolation. Why is this not enabled by default? 17. Under Security Policy, note that the Security Mode is set to disable by default. Why would a guest network's security be turned off by default? (Hint: If it were turned on, what would the guests need before they could use the network?)
18. In the left pane, click Advanced.
19. Click Security.
20. Under Access Control, what is the lAN Client Filter Function? Does it provide strong security if it were enabled?
21. How easy is this user interface to navigate? Does it provide enough information for a user to set up the security settings on this system?
