.CIS3360-21Fall-Wireshark Rev.	2.06c	 CIS3360	Homework	Assignment	 UCF	CECS	 	 	 CIS	3360	–	Security	in	Computing	 Fall	2021	 Homework	Assignment:	Analyzing	Packets	with	Wireshark	 	 Wireshark	is	an	open	source	network	packet/protocol	analyzer.	A	network	packet	analyzer	captures	 network	packets	and	tries	to	display	that	packet	data	as	detailed	as	possible.	Wireshark	is	perhaps	 one	of	the	best	open	source	packet	analyzers	available	today	for	UNIX	and	Windows.	Wireshark	isn't	 an	intrusion	detection	system.	Wireshark	will	not	manipulate	data	on	the	network.	 Legitimate	Uses	of	Wireshark:	 • Network	administrators	use	it	to	troubleshoot	network	problems	 • Network	security	engineers	use	it	to	examine	security	problems	 • Developers	use	it	to	debug	protocol	implementations	 • People	use	it	to	learn	network	protocol	internals	 	 Resources:	 1) The	wireshark	main	page:	http://www.wireshark.org		 2) http://wiki.wireshark.org	 3) http://wiki.wireshark.org/SampleCaptures	 4) http://www.wireshark.org/download/docs/user-guide-us.pdf	 	 Assignment	Part	I	 1.

Capture data from an interface in your computer (e.g., Ethernet or WiFi) (10 points)  • Remember to set the encryption if required  • Store the captured data   3. Store the captured data in a file named captured_LastName_FirstName (3x10 points)  • Break the captured files each 10 seconds and record during 30 seconds (you  should end up with 3 files, each with the name above plus timestamp information)  • Make sure all name resolution options are unchecked. Assignment	Part	III	 1. Load	the	WS1-Assignment-A.pcapng.gz	file	into	Wireshark	 2. What	are	the	two	IP	addresses	of	the	computers	in	the	HTTP	session?	(10	points)	 3. Use	Wireshark’s	data	window	to	examine	the	XML	data	 • Using	the	Go	menu,	go	to	packet	520		 • Use	the	HTTP	view	to	examine	the	captured	XML	data	in	the	packet	 4.
