______________ is a step beyond port scanning that establishes an active connection to help discover useful information such as; user names, service versions or settings, network shares, etc.

Active Reconnaissance Perform this reconnaissance on an authorized internal network. Ensure you have permission prior to scanning since it could be perceived as a precursor of an attack. *NOTE: <IP_Address> represents the IP address from "scanme.org" or an IP address from a device on your network. Download the most current version of Nmap from https://nmap.org/download.html. Open a command prompt and go to the directory where Nmap was installed. Run nmap -h from the command line to see the various options. Please notice that Nmap has many different options. Review and find the option for a full connect scan. Enter the results here: __________. Review and find the option for a stealth scan. Enter the results here: __________. Review and find the option for a UDP scan. Enter the results here: __________. Review and find the option for a fingerprint scan. Enter the results here: __________. Perform a full connect scan on one of the local devices you have identified on the private network. The syntax is nmap -sT <IP_Address>. Enter the results here: __________. Perform a stealth connect scan on one of the local devices you have identified on the private network. The syntax is nmap -sS <IP_Address>. Enter the results here: __________. Perform a full connect scan on one of the local devices you have identified on the private network. The syntax is nmap -sU <IP_Address>. Enter the results here: __________. Perform a fingerprint connect scan on one of the local devices you have identified on the private network. The syntax is nmap -O <IP_Address>. Enter the results here: __________. Observe the results of each scan. Could Nmap successfully identify the system? Were the ports it identified correct?

Reconnaissance: Download and install the Nmap port scanner. Find tutorials for Nmap on their site, your book, and other resources on the web and keep them handy. Understand what you are about to do first! a. Run at least three different scans on your computer (set localhost as target). b. Run a scan on scanme.nmap.org as target. What key differences do you see in the results on your machine vs nmap.org? Research and explain the differences. Reconnaissance: Jane has an intent to penetrate the network in an organization. She has used passive reconnaissance to gather extensive information on the company. She finds out the model numbers of routers and other devices by reading discussions between system administrators in forums. She also has a list of all the IT staff and their phone numbers. She also has the services running on ports on some machines she ran a network scanner on. What reasonable steps should the company have taken to prevent Jane from finding this information? What steps should the company take to prevent or reduce the efficacy of port scans?
