Today I am going to do a quick demonstration of how to easily install a suite of security testing tools from Kali Linux onto a Ubuntu machine. For a bit of background information, Kali Linux is a distribution derived from Debian. Its sole purpose is to provide a suite of tools for penetration testing (pentesting) and forensics. It is provided by Offensive Security, an organization dedicated to providing security training. There is a very long list of tools available for Kali. Such tools include (but are not limited to) forensics, vulnerability checks, access checks, and stress testing.

The latest attack of a worldwide malware, the already famous WannCrypt, has not only made clear the security of hundreds of companies in the world but also how much we sometimes get involved in handling the terminology of these threats.
