We have had innumerable discussions on computer security till today. This article brings to you one of the biggest and the most important tools that every penetration tester or a hacker uses.
Today we are going to introduce you to Kali Linux, a Linux Distribution, which is more of a branch of Debian, but with several specialties. If you have heard of BackTrack, then Kali should be introduced to you more as an updated version of the former. “From the creators of BackTrack comes Kali Linux, the most advanced and versatile penetration testing distribution ever created” that is how Offensive Security Ltd. defines their project. Kali Linux is an operating system specially designed for penetration testing and security auditing. It is an open source software, stuffed with numerous penetration testing tools, discussing and naming all of which is next to impossible, as it has over 300 of them. This blog puts forward my efforts to introduce the readers to the basics of Kali, which will help them get a head start with this OS. Besides the basic utility tools and applications present in every OS distribution, Kali is preinstalled with the best programs and security tools like Hydra (login cracker), Nmap (port analyzer), Wireshark (data packet analyzer), John the Ripper (password cracking tool) and Metasploit Framework (exploit code developing tool), and other tools put together under the category of “Top 10 Security Tools” under the “applications” tab. Initially they might sound Hebrew, but it isn’t that difficult to get a good hold on these tools once you start exploring them.
Latest Version of Kali Linux has released:

Kali also has other tools categorized separately for:
DNS analysis tools
Database Management tools
Open Source Assessment tools
CMS Identification tools
Database Exploitation tools
Web Vulnerability Scanners
Offline Attack tools
Online Attack tools
BeEF XSS Framework
Social Engineering tools
Network Exploitation tools
Network and Web Sniffers
Network Spoofing tools
Voice and Surveillance tools
Misc RE Tools
Network Stress Testing tools
WLAN Stress Testing tools
Anti-Virus Forensics tools
Forensic Analysis tools
Besides these, Kali has numerous other tools too which are among the best security and penetration testing tools ever found. Kali Linux, being a free and open source software, is easily obtainable, and is used by both amateurs as well as professionals. Professionals use it for analyzing vulnerabilities in information systems and networks, for forensic analysis, for finding security exploits, and for applications testing. On peeping into the hackers’ den, Kali can be utilized in breaking security codes, cracking passwords, hacking into Wi-Fi networks, brute force password attacks, network sniffing, IP spoofing and other malicious ventures. However, learners and amateurs can learn a lot from this OS. This distribution probably has enough tools to last for a penetration tester’s lifetime. Therefore a hands-on experience will not only enable a beginner to know new things, but also introduce him to the cutting edge technologies used by the pen testers and crackers. If you are considering a career in information security, then Kali Linux is the best option for you to go for, and start your journey with.
Kali Linux Dual Boot with Windows
Installing Kali alongside a Windows installation can be quite useful. However, you need to exercise caution during the setup process. First, make sure that you’ve backed up any important data on your Windows installation. Since you’ll be modifying your hard drive, you’ll want to store this backup on external media. Once you’ve completed the backup, we recommend you peruse Kali Linux Hard Disk Install, which explains the normal procedure for a basic Kali install.
In our example, we will be installing Kali Linux alongside an installation of Windows 7, which is currently taking up 100% of the disk space in our computer. We will start by resizing our current Windows partition to occupy less space and then proceed to install Kali Linux in the newly-created empty partition.
Download Kali Linux and either burn the ISO to DVD, or prepare a USB stick with Kali linux Liveas the installation medium. If you do not have a DVD or USB port on your computer, check out the Kali Linux Network Install. Ensure you have:
- Minimum of 8 GB free disk space on Windows
- CD-DVD / USB boot support
Preparing for the Installation
- Download Kali Linux.
- Burn The Kali Linux ISO to DVD or copy Kali Linux Live to USB.
- Ensure that your computer is set to boot from CD / USB in your BIOS.
Dual Boot Installation Procedure
- To start your installation, boot with your chosen installation medium. You should be greeted with the Kali Boot screen. Select Live, and you should be booted into the Kali Linux default desktop.
- Now launch the gparted program. We’ll use gparted to shrink the existing Windows partition to give us enough room to install Kali Linux.
3. Select your Windows partition. Depending on your system, it will usually be the second, larger partition. In our example, there are two partitions; the first is the System Recovery partition, and Windows is actually installed in /dev/sda2. Resize your Windows partition and leave enough space (8GB minimum) for the Kali installation.
4. Once you have resized your Windows partition, ensure you “Apply All Operations” on the hard disk. Exit gparted and reboot.
Kali Linux Installation Procedure
Now that you’ve completed installing Kali Linux
The installation procedure from this point onwards is similar to a Kali Linux Hard Disk install
, until the point of the partitioning, where you need to select “Guided – use the largest continuous free space” that you created earlier with gparted
- Once the installation is done, reboot. You should be greeted with a GRUB boot menu, which will allow you to boot either into Kali or Windows.
