In this article, I'm gonna, Take you through the top 5 skills. You need to be learning to get into cybersecurity If you're new to the field or looking for a career transition, There's just so much info out there that it's hard to even get started. You might hear people talk about an alphabet soup of certifications to take, But I'm here, To tell you: THEY'RE, NOT THAT IMPORTANT, While there's some value going through the process of studying for certs. What IS IMPORTANT are your SKILLS and EXPERIENCE, Because in this field, What you can DO will make you so much more successful than what you KNOW. Solving technical problems is THE way to earning the trust and confidence from people you work with Buckle up and let's dive right in Number 1: Building and using virtual machines.
Virtual machines also called VMs, Are operating systems that run on top of your existing or “host” OS. The virtualized OS is commonly referred to as a “guest” and is managed by software called a “hypervisor”. The hypervisor lets you manage and allocate resources like CPU Memory and Disk space on your guest, Popular hypervisors. You may have heard of include Hyper-V by Microsoft, Virtualbox by Oracle. Vmware and KVM Often times when you hear the term “cloud”, It usually means thousands of VMs running on specialized hypervisors on someone else's server farm in a datacenter somewhere Virtual machines.
Let you become platform-agnostic, Meaning you're no longer limited to any particular operating system and tools available for it. Many people spend all their time just on one OS and debate, Which ones are better. Let me tell you: IT DOESN'T MATTER As a pro. You should be versed in ALL of them and comfortable working with any platform, This maximizes the scope of your skills and makes you effective in any situation. Virtual machines also give you the flexibility to train and research in an isolated environment without affecting your main driver.
You can quickly take snapshots of a guest OS and restore it to an earlier state Opening a suspect file. You received Use a VM Want to practice configuring a server Use, A VM Slinging exploits at a target Use a VM Moving on to… Number 2: LEARN the command line Don't run away, But EMBRACE it. The command line interface, Commonly referred to as a SHELL, Is the simplest and arguably the most efficient way to interact with an operating system. For example, If I'm looking for an entry in this CSV file, Excel, Might freeze or crash Running a lightweight shell command gets me what I need in no time Why's, It called a shell.
The important parts of an OS that actually makes it run is called the KERNEL because it functions at the center of the system. The part that's exposed to a user is called the shell since it wraps around the kernel It's, Just like a car where the steering wheel, Pedals and dashboards, Giving you control over the engine or transmission all exist in the “shell” of the car. The command line gives you the lowest level access to software functionality that comes with an operating system. Many of the most useful tools don't have a graphical interface to point and click.
Mastering the command line expands your arsenal and lets you get more done with less It lets you be able to use scripting and automation to tackle repetitive tasks that would otherwise waste lots of time. Automating, Your workflow by learning the command line, Makes you a tremendously valuable asset to the team. I recommend starting out with Bash or the “Bourne-again Shell”, Since it comes default with almost every Linux distribution. Macos used it in its Terminal app, But has since changed to Zsh or “Z-Shell” and has some nicer features.
If Bash is like a Toyota, Then Zsh is more like a Lexus Bash is so popular and effective that Microsoft actually released the Windows Subsystem for Linux or “WSL” and lets you install several different Linux flavors to use Bash as a native app. This is super convenient, Since I can access most of my Linux tools without having to switch to a virtual machine, Now understand that Powershell is actually the go-to native shell for Windows, It's very different from how you would use the Linux command line, But gives you a Ton of powerful Windows administration abilities, If you work in an environment where Windows is the primary OS, Definitely learn Powershell as well. I'M gonna start a series on the Linux command line very soon Comment below to. Let me know what tools and concepts you'd like to learn. Number 3: System Administration - All of us with a computer or smartphone from your grandma to IT.
Wizard is a really sysadmin at some level. It all depends on what level you're at System administration involves the configuring and maintaining of computers, Whether a personal device or hi-powered server. When I was first using computers as a kid, I loved to dive down into EVERY SINGLE SETTING available on the computer just to see what it did, Reading manuals online guides and playing around just drove this curiosity. Further.
By doing that, I became the family. It help desk System administration is about knowing your platform and various tools inside and out to be able to help others who don't Whatever your skill. I challenge you to fiddle around and learn by doing, Delete some files and try to recover them. Download open and monitor old viruses in a virtual machine with tools like Windows, Sysinternals, To see what t do: Try to extract files and passwords off a computer without knowing the login info, Whatever it is, Push the limits of what you already know by reading guides out.
There and following along Practice, A little more each day and you'll level up in no time Next, Up… Number 4: Computer Networking. This is the heart and soul of it all. What I like to call the cyberspatial “laws of physics” It's understanding how devices interact with each other and how data gets from point A to point B, A strong foundation in networking will make you a rockstar troubleshooter, Whether you're red teaming defending or running day-to-day. It ops There's two conceptual models that govern computer, Networking:, TCP/IP and OSI.
T group all your different networking and telecommunication protocols into “layers” TCP/IP is older and uses four layers: network access, Internet transport and application layers. OsI stands for the Open System; Interconnection which is developed by the International Organization for Standardization or ISO. These define everything from country codes to time and date. Formats OSI is newer and uses seven layers: physical datalink network transport session presentation, Application layers.
All these layers are just a way to describe “what's happening where”. So, If you're receiving a package from someone in a different country, It's gonna get passed between envelopes, Boxes, Vehicles and planes, Each with their own addressing method and operating procedures. When the post office tells you there's an airline issue, You know where it is in the transportation system. That'S delaying your delivery. Likewise, The networking layers all have different functions, But as a whole work together to let you stream articles from a server in a rack to a device in your hands.
Knowing what's happening at each layer. Lets you “see the matrix” and be much more skilled at your craft Number. 5: Personal digital security. This is an area I've been particularly passionate about because it affects our families, Friends and organizations. The cybercrime industry is booming.
You don't have to scroll far to see what the online black market place looks like, As technology becomes more intertwined with our lives from Internet-connected cars to refrigerators, The vulnerabilities and attack vectors are gonna increase more and more. If you want to go deep into cybersecurity, There's. No better place to start than with yourself From passwords encryption to secure comms stay up-to-date with the latest security news and best practices. You might just be the subject-matter expert in your office that others go to for advice And that advice might just protect your company from becoming front page news, But, Most importantly, Is living it out yourself as well.
Clearing the Certification isn’t considered to be that much easy, you have to go through rigorous training and lots of Cisco 300-710 Practice Questions would be needed to go through unless you have some expertise training courses like such offered at the EveDumps.
