Kali Linux is a Debian-derived Linux distribution designed for digital forensics and penetration testing

Kali Linux has over 300 preinstalled penetration-testing programs, including Armitage (a graphical cyber attack management tool), Nmap (a port scanner), Wireshark (a packet analyzer), John the Ripper password cracker, Aircrack-ng (a software suite for penetration-testing wireless LANs), Burp suite and OWASP ZAP web application security scanners.[2][3] Kali Linux can run natively when installed on a computer's hard disk, can be booted from a live CD or live USB, or it can run within a virtual machine. It is a supported platform of the Metasploit Project's Metasploit Framework, a tool for developing and executing security exploits.[2]

It was developed by Mati Aharoni and Devon Kearns of Offensive Security through the rewrite of BackTrack, their previous information security testing Linux distribution based on Knoppix. The third core developer Raphaël Hertzog joined them as a Debian expert.[4][5]

Kali Linux is based on Debian Testing. Most packages Kali uses are imported from the Debian repositories.[6]

Kali Linux is developed using a secure environment with only a small number of trusted people that are allowed to commit packages, with each package being digitally signed by the developer. Kali also has a custom-built kernel that is patched for 802.11 wireless injection. This was primarily added because the development team found they needed to do a lot of wireless assessments.

Penetration Testing vs Ethical Hacking

Difference between Penetration Testing and Ethical Hacking. Penetration testing is very closely related to ethical hacking, so these terms often used interchangeably, but they do have distinctions that we should observed.

Penetration testing is a more narrowly focused phrase, it deals with the process of finding flaws in a target environment with the goal of penetration systems, taking control of them. Penetration testing, as the name implies, is focused on penetration the target organization’s defenses, compromising systems and getting access to information.

Ethical hacking is an expansive term encompassing all hacking techniques, and computer attack techniques to find security flaws with the permission of the target owner and the goal of improving the target’s security while penetration testing is more focused on the process of finding vulnerabilities in a target environment. In short, penetration testing is a subset of ethical hacking.

Kali Linux Network Scanning Cookbook

will introduce you to critical scanning concepts. You will be shown techniques associated with a wide range of network scanning tasks that include discovery scanning, port scanning, service enumeration, operating system identification, vulnerability mapping, and validation of identified findings. You will learn how to utilize the arsenal of tools available in Kali Linux to conquer any network environment. You will also be shown how to identify remote services, how to assess security risks, and how various attacks are performed. This immersive guide will also encourage the creation of personally scripted tools and the development of skills required to create them.
