LAB 1: Footprinting a Network

One of the most astounding side-effects of the Internet is how readily accessible information is about individuals, organizations, and computer systems. This assignment is designed to give you some experience in obtaining this information.

Materials Needed:

• Computer
• Internet connection with NSLookup available.

Activity

• Use NSLookup to determine the IP address of jaring2.ColumbusState.edu and cs.ColumbusState.edu (you may substitute your computer on your campus)
• Determine who administers these computers and any other information readily available. You may use any websites or tools like ARIN, Neotrace, Whois, or other open source public information. Describe how you found the information. You now have all kinds of information that would allow you to take advantage of vulnerabilities at that site.
• Web servers are notorious for containing large numbers of vulnerabilities. Download NetBrute (http://www.rawlogic.com/products.html) to determine the following: What computers in the class C range of IP addresses found above are running web servers (check for port 80)?
