BN303 - WLAN Security: Analyzing Wireless Network with Sniffing Tools

This report provides an in-depth analysis of wireless network security using WLAN sniffing tools. It begins by recording WLAN access points for home, public, and work networks, followed by a detailed technical information section. The report then focuses on the use of Wireshark as a WLAN sniffing tool, providing evidence of packet capturing, evaluations of capture time, total captured packets, protocols, throughput, and round trip time. Finally, it offers recommendations for managing and securing WLANs, including modifying the default SSID, using strong encryption, deploying authentication, and monitoring the exterior building and site. The report concludes with a list of references used for the analysis and recommendations.

1.3 WLAN sniffing tool
The wireless sniffer is one of packet analyser and it is designed to intercept the data as it
is transmitted over a network and decode the data into a format which is readable for humans.
The wireless sniffer is specifically designed for capturing the data on wireless networks. This
tools has the various uses in IT environments. It has following ability like decode, intercept
and monitor the data that are transmitted which is useful for following aspects,
 Filtering the network traffic
 Monitoring the network security, activity and usage.
 Identifying the configuration issues
 Identifying the network bottle necks
 Investigating and diagnosing the network problems
Here, we are using the Wire shark sniffing tool to capture the home network details [4].
1.3.1 Evidence
To capture the packets by follows the below steps.
First, open the wire shark and choose the home wireless network connection. It is shown
below.
