In this tutorial, I will be going to guide you on how to install OpenVAS in Kali Linux.OpenVAS is an open source vulnerability scanner and management tool.It can save a lot of time when you are performing a vulnerability analysis and assessment. Using an automated up to date vulnerability scanner in penetration testing often helps you to find vulnerabilities that can be found easily during a manual assessment.

So, let's Start How you can install OpenVAS on Kali Linux.
First Of all open Linux command terminal to download and install OpenVAS:
Type In Following Commands:
