Wk 5: Packet Capture Analysis

You are analyzing packet captures from a wireless network to assess if the captures pose a threat, what risks, if any.

For this assignment, analyze the packet captures provided by Wireshark by doing the following:  

Go to the Wireshark Sample Captures site, and download the following:

• wpa-Induction.pcap.gz Wi-Fi 802.11 WPA traffic  
• wpa-eap-tls.pcap.gz WiFi 802.11 WPA-EAP/Rekey sample   
• nb6-hotspot.pcap Someone connecting to SFR's wireless community network 
• ciscowl.pcap.gz (libpcap) Cisco Wireless LAN Context Control Protocol (WLCCP) version 0x0 
• wap_google.pcap contains two WSP request-response dialogs

Note: Only download these sample captures. Other captures may set off your computer's system defenses.

Use Wireshark to view and analyze the sample captures.

Create a 1-page table that ranks the packet captures from the highest to lowest threat. In your table provide the following for each packet capture:

• Description of the traffic
• Description of the risks, if any, the traffic poses to the wireless network
• Countermeasures to take to secure network from any threat

Write a 1/2- to 1-page memo to management as a network security specialist explaining the following:

• How you can distinguish hostile packet data from normal packet data
• How you can recognize any attack signatures in the packets you analyze
• Provide a rationale for ranking the packets as you did
