NETW 360 NETW360 iLab 6 Evaluating Security-Related WLAN Problems Solution

Scenario I: Signal Spillage

 

1. Compare the physical boundary of the building to the signal coverage area. Name a couple of locations where the incidents of signal spillage occur (e.g., the northwest corner)?

 

2. Assume the external antennas being used are all omni-directional with an antenna gain of 2.14 dBi. Given all other conditions remain the same, how would relocating some of the access points to a different part of the floor help reduce the amount of signal spilling outside of the building?

 

3. Given all other conditions remain the same, how would replacing some of these antennas help reduce the amount of signal spilling outside of the building? What type of antennas would you recommend?

 

4. Given all other conditions remain the same, how would adjusting the power level of some access points help reduce the amount of signal spilling outside the building? What undesirable outcome, from the signal coverage perspective, will likely be caused by such isolated adjustments?

 

5. Research a couple of other methods that could help reduce signal spilling outside of a building.

 

Scenario II: WLAN Security Standards

 

1. Refer to the diagram above. Is the network, as well as the information transmitted on the network, protected from eavesdropping?

 

2. Among the typical security standards, such as WEP, WPA personal, WPA enterprise, WPA2 personal, and WPA2 enterprise, which one is best suited for the intended use of the “Monitor” network as described in this scenario?

 

3. Justify your recommendation in the previous question.

 

Scenario III: Rogue Access Points

 

1. Refer to the screenshot. What’s the name of the identified rogue access point?

 

2. Given the inSSIDer software installed on a laptop, how would one go about physically locating this rogue access point?
