Network Discovery

Purpose

This document describes how to set up a Network Host Discovery scan.

Introduction

A Network Discovery scan helps identify and list all hardware and software assets within an organization's network infrastructure. It does this by sending packets using various protocols like ARP, ICMP, TCP, and UDP. If the scanner receives a response from the target, it confirms that the target is active and it can be added as an Asset along with the asset identifiers.

Setting up a Network Discovery Scan

To configure a Network discovery scan:

1. Select the Network discovery radio button.

   

2. Enter a Name for the configuration.

3. Enter Targets for the configuration. These can be in the format of IPv4, IPv6, Hostname, IPv4-CIDR , IPv4-range, separated by newline.

4. Choose a scanner from the drop-down menu.

5. Click the ADD button to save the configuration.

Setting Ports Manually

Ports can be manually set to a saved network discovery scan

1. Open a previously saved discovery scan by clicking on it.

   

2. Go to the Port scanning section at the bottom.

3. Fill in the ports you want to scan. The port range expression format accept comma separated items such as a port (22,25), a range (20-80), an exclusion (!25565), default range (def), or no ports should be scanned (none).
