ICT60215 ICTNWK607: Wireless Network Security Case Study Analysis

This case study focuses on Red Enterprise's wireless network issues. The scenario describes slow wireless traffic, high delays, and packet loss. The network consists of wired and wireless segments connected by a Cisco 1811 wireless router (R1). The wireless traffic lacks encryption, and initial tests reveal poor performance even at close range to the access point. The assessment requires analysis of the relevance of physical distance, the drawbacks of static channel assignment, and identification of the 802.11b/g operating standard. The case study assesses the student's ability to diagnose and propose solutions for wireless network security problems, reflecting real-world workplace scenarios. The student needs to provide answers to the questions related to the scenario, demonstrating their understanding of wireless network principles and troubleshooting techniques.

CASE STUDY
The Scenario:
Red Enterprise is having trouble with the wireless section of their
network. While the wired portion works fine, the wireless traffic is too
slow.
Red network can be divided in 2 sections: wired and wireless. The 2
sections are connected by Cisco 1811 wireless router (R1) which is also
used to route packets to/from The Internet (devices located outside
Red’s Network). The wireless traffic is being transmitted clear (no
encryption used).
The topology is shown below:
High Delays and Packet Loss
You get to Red’s office and connect to their wireless network using your
laptop’s wireless card. The association process (between your laptop
and Red’s Access Point – R1) takes longer than usual and you decide to
run a few tests.
Once your laptop is associated with Red’s Wireless Access Point (Cisco
1811) you issue a few pings from it. Pings issued from your laptop to any

address (inside Red’s network or internet addresses) have high response
time and high loss rate.
You suspect the walls are weakening the signal and decide to move
closer to the AP. From a closer spot you issue the pings again and
although the shorter physical distance, the loss rate and delay are still
very high.
Question 1: Is physical distance relevant when it comes to wireless
traffic throughput?
Question 2: Even though is possible to find a good channel to be
statically assigned to Red’s AP, why is this not a good idea?
Question 3: How do you know it is operating on 802.11b/g?
