Implementing vulnerable systems

In this section, you’ll learn how to set up the OWASP Juice Shop vulnerable application on Kali Linux to safely learn how to perform active reconnaissance on web applications. Additionally, you will learn how to set up Metasploitable 3 Windows VM as a virtual machine within our lab environment.
