Lab 1 nmap scan

Open a second terminal window. By using scanners such as Nmap, the attacker are able to sweep networks and look for vulnerable targets.

Return to the second terminal window. The usage syntax of Nmap is fairly simple. Shutting Down When you are finished with the exercise, do not shut down your virtual machines; you will use the same network setup in the next exercise.

Hosts that respond to either will be considered by Nmap to be up. Conduct an IP protocol ping on yourself. You will be required to try out all the NMAP commands on the sniffer labeled R host that belongs to your assigned pod.

Investigate how to restrict the application scans to specific sets of port numbers, otherwise your scans may take a long time to complete. In addition, Nmap will allow you to specify networks with wild cards, such as How to use NMAP? Nmap can also use TCP stack fingerprinting to accurately determine the type of machine being scanned.

Nmap can be downloaded free of charge from http: Nmap is very flexible in specifying targets. Note that nmap also has a GUI front end named zenmap. Part 3 - Using nmap to conduct a reconnaissance of your network Leave the nmap man page open for reference. Students will be given the root privilege to finish all the questions in section 6.

Does this make sense? A ping scan, for example, is "-sP". NMap Lab Exercise Note: Be paitent, this will take a while. Options are then specified, followed by the hosts or networks to be targeted.

Specifically you have used the network port scanning tool nmap. While you explored this tool using the Linux operating system, the same tool is available for Windows operating systems.

This is usually done with a ping scan by using the "-sP" flag.

Run a Zenmap Scan

Open a third terminal window. What happens if you rerun this command without the -n option?

In our exercise, the students are given the root privilege. Note that for this scan "nmap needs to read raw responses off the wire"; you must use sudo to have sufficient privilege.

In this example, scan all hosts on the Conduct an IP protocol scan switch -sO on host Once these targets are identified, an intruder is able to scan for listening ports. Specifically enter the following scans: All the exercises on Nmap should be done on the router.

Use a broad ping scan to determine the hosts that are "up" on a portion of your lab network. Conclusion In this exercise you have learned the usefulness of one of the most common utilities for exploring a network using port scans.

There are a few graphical front ends; however, our lab exercise will focus on using Nmap in the command-line.View Lab Report - Lab #1 – Assessment Worksheet from CYBER SECU IS at ITT Tech Pittsburgh.

1. What is the first Nmap command you ran in this lab? Explain the switches used. nmap -O -v. Nmap is a network mapping tool used to scan networks for live hosts, certain services, or to determine specific operating systems (Orebaugh & Pinkard, ).

Based on the lab, Nmap has many features that can be used to obtain a. Home» Run a Zenmap Scan Run a Zenmap Scan. This exercise complements material in the CompTIA Security+: Get Certified Get Ahead: SY Study Guide.

If you haven’t, you can follow the instructions in the Download and Install Nmap lab. 1) Use ipconfig to identify your IP address and subnet mask. If you don’t know how to do so.  Nmap LAB EXERCISE CSEC LAB-1 University of Maryland University College B-McDerm February 16, ASSIGNMENT PART A-NMAP Lab Questions: Part A 1.

Nmap LAB EXERCISE CSEC LAB-1 University of Maryland University College B-McDerm February 16, ASSIGNMENT PART A-NMAP Lab Questions: Part A 1.

Simply scan one host or scan entire networks by pointing Nmap to the network address with a "/mask" appended to it.

In addition, Nmap will allow you to specify networks with wild cards, such as *, which is the same as /
