Network Mapping and Target Identification

One of the first phases of a network security assessment is to network mapping which identifies devices on the network. In this Lab, you will use a variety of tools in Kali Linux to map out a local network to identify targets by discovering hosts on the network. You will understand the difference between how tools scan local networks and remote networks. You will also understand the detection capabilities of each approach. The local network for this Lab is contained within a Hyper-V virtual environment. The hosts on the network consist of a variety of Linux and Windows hosts.

This Lab is designed for the CREST Practitioner Security Analyst (CPSA) certification examination but is of value to security practitioners in general.

Lab Objectives

Upon completion of this Lab you will be able to:

• Scan for active network devices using the following tools:
  • The ARP Scanner (command line tool)
  • Nmap (command line tool)
  • Zenmap (graphical user interface)
• Understand the approaches taken for scanning local networks versus remote networks including the request type packets

Lab Prerequisites

You should be familiar with:

• Working at the command-line in Linux

You can fulfill the prerequisites by completing the Linux Command Line Byte Session Learning Path.
