Learn the steps to install Metasploit Framework on Ubuntu 22.04 LTS Jammy JellyFish Linux using command terminal.

What is Metasploit?

Metasploit is an open-source project that provides, among other things, the Metasploit framework. It includes a collection of exploits that can be used to test the security of computer systems. Often, apart from developers or testers, it is also used by hackers.

If we talk from the legal angle, the framework provided by the Open Source Metasploit project is mainly used to test computer systems for security vulnerabilities. It offers a set of exploit tools to perform a wide variety of security and penetration tests that can be performed on distributed target systems. Even software developers can use it to test their software to find potential flaws.

Metasploit Framework developers used the Ruby language to create it, and it is available to be installed on various operating systems. It includes all major Linux and Unix, macOS and Windows versions. Generally, users have to install it manually, however, penetration Linux distributions such as Kali out-of-the-box offer Metasploit.

In addition to command-line oriented input, graphical user interfaces are available for easier operation. The framework is extensible in different languages ​​via add-ons.

The framework offers a modular structure and distinguishes the tasks of developers and attackers. There is a separation between the attack methods (exploits) and the code to be executed. Exploits should be tailored specifically to different software and hardware vulnerabilities. The code is used when an attack method has succeeded and the system can be infiltrated or compromised.
