packet capture analysis

/in /by

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: ATTACHED IS THE NECESSARY FILES IN A ZIP FOLDER

  • 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
