Lab 08 - Network and Vulnerability Scanning


The purpose of this lab is to introduce you to NMAP and OpenVAS on kali.

Lab Goals

  1. Use NMAP to scan each of the computers to determine open ports.
  2. Use OpenVAS to scan all computers on your network - including Windows.


You need GUI access to your Kali machine, and all your machines must be on.

  1. Report all open ports using NMAP.
  2. Download and install OpenVAS on your Kali machine. Why it's not already there? I'm not sure.

    1. I also had problems with this step because updates were not happening correctly.
    2. The fix was simple: always used the mirror, so I changed it to be hard coded in /etc/apt/sources.list to use Hopefully next year this will be fixed.

Show Me

  1. Show the NMAP output reports nicely organized - pick a tool.
  2. Show Greenbone Working by showing an OpenVAS scan of all your computers.


In 2021, we had problems getting files to sync.

It seems that they might be limiting us to one download per IP. Kendric got the following to work:

sudo apt install rsync
sudo greenbone-scapdata-sync --refresh
