Kali Linux is a popular term for anyone related to computer security. It is the most renowned tool for advanced Penetration Testing, Ethical Hacking and network security assessments.
To know more about Kali Linux more closely, we recently had a quick chat with Glen D. Singh, a cyber security instructor and an Infosec author with Learn Kali Linux 2019 being his latest book. In his book, Glen explains how Kali Linux can be used to detect vulnerabilities and secure your system by applying penetration testing techniques of varying complexity.
Talking to us about Kali Linux, Glen said that the inclusion of 300 pre-installed tools makes Kali Linux an arsenal for any cybersecurity professional. In addition to talking about certification options for both novice and experienced cybersecurity professionals, Glen also shared his favorite features from the latest Kali Linux version 2019.3 among other things in this deeply informative discussion.
On why the cybersecurity community loves Kali Linux and what’s new in Kali Linux 2019.3
What makes Kali Linux one of the most popular tools for penetration testing as well as for digital forensics?
The Kali Linux operating system has over 300 pre-installed tools for both penetration testing and digital forensics engagements, making its single operating system an arsenal for any cybersecurity professional.
The developers of Kali Linux are continuously working to create rolling updates, new features and new upgrades to the existing operating system. Today, you can even deploy Kali Linux on various cloud platforms such as Microsoft Azure, Amazon AWS and Digital Ocean. This allows you to create a beast of a machine with any scale of computing resources, while allowing you access from anywhere.
Furthermore, being a Linux-based operating system is one of the best things that makes Kali Linux popular. This is because Linux is a very powerful operating system with already built-in security, rolling updates, and security fixes, and is very light on computing resources as compared to other operating systems. Kali Linux can even be installed on a Raspberry Pi, making it a custom network implant device.
Finally, what I love about Kali Linux is the fact that you can create a live USB with multiple persistence stores and apply the Linux Unified Key Setup (LUKS) Encryption Nuke, providing the options to wipe the stores using a Nuke password.
What are the features that excited you in the latest Kali Linux version, 2019.3, and why? According to you, how will these additions help Kali Linux grow as a community and for individuals using it?
One feature I’m definitely excited about in Kali Linux 2019.3 is the support for LXD Container Image. This feature will allow you to experience virtual machines on Kali Linux but instead of using a hypervisor, you’ll be using Linux containers instead. This provides some major benefits such as easy to scale containers, support for networking and storage management with security.
Kali Linux 2019.3 has support for the new Raspberry Pi 4, which has an improved CPU and faster memory as compared to its predecessor. With the new upgrades to Kali Linux 2019.3, the pentesting operating system can take advantage of the 64-bit CPU on the new Raspberry Pi 4, thus maximizing the computing power in the tiny ARM device.
Definitely I can see cybersecurity enthusiasts having a lot more fun creating Linux-based containers in their Kali Linux 2019.3 version. Many will be excited to purchase a credit-sized computer, the Raspberry Pi, 4 for setting network implants and remote access configurations that are ready to be deployed.
Glen’s journey in the cybersecurity sector and a few certification recommendations for a career upgrade
Tell us about your evolution in cybersecurity.
As a teenager, I was always fascinated by computers and how technologies work together. Upon completing my secondary level education, I began to pursue my first IT certification, this was CompTIA A+. During this certification, I was introduced to computer security and this had caught my attention a bit more than other topics. Later on, I pursued the CompTIA Network+ certification and this where network security caught my attention. Of course, I’m sure you can guess the next course of pursuit, the CompTIA Security+. This certification was the one which helped me realize my love for IT Security was growing and this is what I want to pursue as a career.
After completing my studies in CompTIA Security+, I realized that I had to make a big decision in choosing the specialization. The decision was a bit tough at the time, I decided to enroll for the Certified Ethical Hacker (CEH) programme. This was it for me, my first major certification in IT, my love for cybersecurity grew even more as I wanted to specialize in offensive security tactics next.
There onwards, I have continued to harness my skills in discovering vulnerabilities and learning about new hacking techniques. I had often wondered to myself at the time – If I can hack, surely there must be methods a digital forensics professional can use to find the malicious user. I decided to pursue the Computer Hacking Forensics Investigator (CHFI) certification as a natural progression in my journey to understand everything there is about cybersecurity. This has taught many things about operating systems, network and email forensics and so on.
Additionally, I did a couple of firewall certifications and training such as CCNA Security, Check Point CCSA and Fortinet as I wanted to learn more about how firewalls operate to protect organizations and improve network security.
During this time, I was working in an administrative position, however my certifications allowed me to gain employment within the IT industry as a security professional at various companies. However, growth was a bit challenging in some of my past positions while my pursuit to continuously expand my knowledge was growing. Eventually, I began lecturing Cisco certification programmes and gradually took over cybersecurity certifications and training programmes at various institutions. This opportunity allowed me to grow a lot while working with others, develop secure network designs and strategies, develop training programmes, train persons in both private and public sectors ranging from ISPs to government agencies in the field of cybersecurity.
In 2018, Packt Publishing had reached out to me to be a Technical Reviewer for the book, Penetration Testing with Shellcode. After this project was completed, Packt had reached out once again in the same year, this time to be the Lead Author for the CCNA Security 210-260 Certification Guide and before 2018 was completed, I had my second book CompTIA Network+ Certification Guide published. In early 2019, my third title Hands-On Penetration Testing with Kali NetHunter was also published. Finally, in November 2019, my fourth book Learn Kali Linux 2019 is now published.
Currently, I work as a Cybersecurity Instructor delivering training in offensive security, network security and enterprise networking. Additionally, I share my knowledge and guidance with others through various social media platforms, provide mentoring for anyone in the community within ICT, occasionally delivering speeches on cybersecurity awareness.
Following my dreams is what has led me to my career in cybersecurity, where I can help so many people in a lot of different ways, to secure their organizations or even safeguard their families from cyber-attacks and threats. I honestly love what I do, so I don’t see it as “work” but my passion.
Given the pace of change in tech and evolving threats, what role do certifications play, if any? What must-have certifications do you recommend for those starting their cybersecurity career and for those looking for a career boost?
Certifications will always play a vital role in the cybersecurity industry in both the present and future as technologies and threats evolve. Being a certified professional in the industry’s latest certifications helps with growth in your career. It also proves you have the necessary skills required for a job role and helps you specialize in technologies making you stand out from the rest of the crowd.
Whether you’re starting a career in cybersecurity or simply looking for a career boost, there are some must-have certifications I would definitely recommend.
If you’re new to the field of cybersecurity I would personally recommend starting with a networking certification such as Cisco Certified Network Associate (CCNA) as it will help you develop a solid foundation in understanding the functions of networking components and protocols, composition of network traffic as it’s passed along multiple networks, and how devices are interconnected and communicate. Networking knowledge will help you understand how cyber-attacks are delivered through the internet and corporate networks.
Secondly, I would recommend both the Certified Ethical Hacker (CEH) certification from EC-Council and Offensive Security Certified Professional (OSCP) certification from Offensive Security. The CEH contains a lot of valuable information and will help you get through the doors of Human Resource (HR) and various national security agencies, however the OSCP is currently in higher demand in the cybersecurity industry due to its intensive hands-on training and practical testing, thus simulating a real-world penetration test.
Additionally, if finances are a bit challenging in one’s life, take a look at the Junior Penetration Tester (eJPT) and the Certified Professional Penetration Tester v2 (eCPPTv2) from eLearnSecurity.
Before choosing a cybersecurity certification to enroll, take a thorough look at the module each certification has to offer and ensure each new certification you decide to pursue either teaches you something new or expands your existing knowledge and skill-set as a professional. Last by not least, learn some Linux.
