Five Skills You Need To Learn To Work In CyberSecurity

Constructing and Utilizing Virtual Machines

Virtual machines, called VMs, encompass operating systems atop your current or “host” OS. The virtualized operating system is commonly labeled as a “guest” and is governed by software termed a “hypervisor.”

This hypervisor enables resource management and allocation within your guest environment, such as CPU, Memory, and Disk space. Renowned hypervisors you might recognize include Microsoft’s Hyper-V, Oracle’s Virtualbox, VMware, and KVM.

When the term “cloud” often arises, it denotes numerous VMs operating on specialized hypervisors situated within external server farms, often within data centers.

While individuals often devote their time to a single OS and engage in debates regarding their superiority,  such debates are inconsequential. As a professional, your expertise should span all OSs, allowing you to operate confidently in any environment.

This broadens your skill set and enhances your efficacy across diverse scenarios. 

Mastering the Command Line Interface

The command line, arguably the most efficient method to interact with an operating system, offers a straightforward approach. For instance, Excel may falter or crash when seeking an entry within a CSV file, whereas a lightweight shell command swiftly provides the needed information. Wondering about the name “shell”?

The kernel, the vital component driving an OS, operates at its core. The user-accessible layer, called the shell, encapsulating the kernel, much like a car’s interior, encompasses the controls steering the engine or transmission. 

Numerous invaluable tools lack a graphical interface, necessitating command-line mastery. Proficiency in this realm broadens your toolkit, allowing you to achieve more with less effort.

Scripting and automation, enabled by command-line prowess, efficiently address repetitive tasks, saving considerable time. 

Transforming your workflow through command-line skills elevates your value within the team. It’s advisable to commence with Bash, the “Bourne-again Shell,” pre-installed on nearly all Linux distributions. While macOS initially featured 

Within its Terminal app, Bash transitioned to Zsh, the “Z-Shell,” offering enhanced features.

Bash’s popularity led Microsoft to introduce the Windows Subsystem for Linux (WSL), allowing the installation of various Linux flavors for native Bash utilization. This convenience eliminates switching to a virtual machine to access Linux tools.

System Administration

System administration isn’t confined to IT experts alone; it encompasses individuals across the spectrum, from tech-savvy grandparents to seasoned IT wizards, each operating at varying levels.

This diversity hinges on your proficiency level. System administration entails the setup and upkeep of computers, whether on a personal device or a robust server. 

System administration revolves around an in-depth comprehension of your platform and the array of tools at your disposal, enabling you to assist those who lack such expertise. Irrespective of your current skill level, engage in hands-on exploration and learning through experimentation.

Delete files intentionally and then endeavor to recover them. Operate within a virtual machine, utilizing tools like Windows Sysinternals to dissect outdated viruses by downloading, opening, and monitoring their actions.

Attempt to extract files and passwords from a computer without access to the login credentials. In each scenario, extend the boundaries of your existing knowledge by following the guides available and participating actively. 

Computer Networking

Computer networking serves as the fundamental bedrock in the realm of cyberspace. It revolves around comprehending the interplay of devices and the data journey from one point to another.

A solid grounding in networking transforms you into a troubleshooter extraordinaire, whether in red teaming, defense, or everyday IT operations. The computer networking domain is governed by two pivotal conceptual models: TCP/IP and OSI, which organize diverse networking and telecommunication protocols into distinct “layers.”

TCP/IP, the older model, operates across four layers: network access, internet, transport, and application.

In contrast, OSI, an acronym for Open System Interconnection, is a more recent construct developed by the International Organization for Standardization (ISO). ISO’s contributions range from country codes to time and date formats. OSI comprises seven layers which are: physical, datalink, network, transport, session, presentation, and application.

Proficiency in each layer allows you to “perceive the matrix,” elevating your expertise to a new level in your craft.
