About the Kali Linux Distribution
Kali Linux is an open source project that is maintained and funded by Offensive Security, a provider of world-class information security training and penetration testing services. In addition to Kali Linux, Offensive Security also maintains the Exploit Database and the free online course, Metasploit Unleashed.
Kali Linux requires a minimum of 20GB hard disk space for installation.
A minimum of 1GB RAM for i386 and AMD64 architectures.
A bootable CD-DVD drive or a USB stick.
Kali Linux is distributed in 32-bit and 64-bit images for use on hosts based on the x86 instruction set and as an image for the ARM architecture for use on the BeagleBoard computer and on Samsung’s ARM Chromebook.
The developers of Kali Linux aim to make Kali Linux available for ARM devices.
Kali Linux is already available for BeagleBone Black, HP Chromebook, CubieBoard 2, CuBox, CuBox-i, Raspberry Pi, EfikaMX, Odroid U2, Odroid XU, Odroid XU3, Samsung Chromebook, Utilite Pro, Galaxy Note 10.1, and SS808.
With the arrival of Kali NetHunter, Kali Linux is also officially available on smartphones such as the Nexus 5, Nexus 6, Nexus 7, Nexus 9, Nexus 10, OnePlus One, and some Samsung Galaxy models.
Kali Linux has a dedicated project set aside for compatibility and porting to specific Android devices, called Kali Linux NetHunter.
It is the first Open Source Android penetration testing platform for Nexus devices, created as a joint effort between the Kali community member “BinkyBear” and Offensive Security. It supports Wireless 802.11 frame injection, one-click MANA Evil Access Point setups, HID keyboard (Teensy like attacks), as well as Bad USB MITM attacks.
BackTrack (Kali’s predecessor) contained a mode known as forensic mode, which was carried over to Kali via live boot. This mode is very popular for many reasons, partly because many Kali users already have a bootable Kali USB drive or CD, and this option makes it easy to apply Kali to a forensic job. When booted in forensic mode, the system doesn’t touch the internal hard drive or swap space and auto mounting is disabled. However, the developers recommend that users test these features extensively before using Kali for real world forensics.
Kali Linux includes many well known security tools, including:
John the Ripper
