Question

After installing Winpcap and Nmap,

Launch “Command Prompt” by typing “cmd” in “start> run”

Enter into C:program files map, which should be the default directory for your installation

Enter command “nmap -P0 -O -A ”+ an IP address or a domain name, and wait for a few minutes to see the results; Here “–P0” means scan all ports; “-O” help you identify the OS running on the host computer; “-A” enable OS detection, version detection, script scanning, and traceroute. Make sure there is a space between the command and the option as well as between options!

Use the same command above to scan a computer in your house and see the results – you may use domain name or IP address of the computer. For example, “nmap –P0 -O -A 192.168.0.1”

If you can obtain agreement from a remote host owner, you may scan the host/server with its domain name or IP address.

Please answer following questions in your lab report

1) Submit answers to the following questions based on the reports you generated.

a) Did you find any vulnerability with the computer you scanned?

b) What operating systems are running on the hosts you visited?

c) List several services running on each computer?

d) Identify one high severity vulnerability for each computer (if there is one). Describe the vulnerability and discuss control(s) to minimize the risk from the vulnerability.

Explanation / Answer

a) In computers or we can say that in information technology,vulnerability is termed as the flow in the design or code that creates a point known as potential which comprises the security for the network or any other endpoint and Yes ,there is the vulnerability with the computer we scanned.

b) The operating systems running on the hosts we visited is linux because its a open network linux or open compute system.

c) Services running on each computer may be are icmp general,udp general,tcp general and udp mdns.

d) High severity vulnerability for each computer is that the bugs in it can be used to be exploited to read ,write or delete all the files stored in the server or exploitely shut down the server immediately by having some changes in it.

Vulnerability basically means if there is the possibility of anything or something to be harmed or attacked by any anyone by any source or means of attack.

The risk of the vulnerability can be controlled or minimized by keeping files with passwords and then encryption should be applied on them so that noone can view or attack that file.And yhe passswords which are assigned should be assigned by the security administrator in the logon of first time.The transaction data file access should be deleated.In this way,the risk of vulnerability can be minimized.
