In this blog, I'm going to take you through the top five skills, learning to get into cybersecurity.
If you're new to the field or looking for a career transition, there's just so much into 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 that while there's some of them through the process of studying for certs, what is important are your skills and experience because of this field will make you so much more successful than solving technical problems. The way to earning the trust and confidence from people you work with.
And let's dive right in.
1..Number one building using virtual machines, virtual machines, also called VMs, or operating systems that run on top of your existing virtualized though as it's commonly referred to as a guest, and it's managed by software called a hypervisor. The hypervisor lets you manage and allocate resources like CPU, memory and disk based on popular hypervisors you may have heard of include Hyper V by Microsoft Virtual Box by Oracle, VMware and KVM. Oftentimes, when you hear the term cloud, it usually just means 1000s of VMs running on specialized hypervisors on someone else's data center somewhere, virtual machines like you become platform agnostic, are no longer a particular operating system and tools available. Many people spend all their time just on LS 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 be comfortable working with any. This maximizes the scope of your skills makes you effective. Any situation. Virtual machines also gives 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 of suspect while he received use a VM. Want to practice configuring a server using VM slinging experts to target use the VM moving on to
2.Number two, learn the command line interface commonly referred to as a shell, and the simplest, arguably the most efficient way to interact with an operating system. For example, I'm looking for an entry in the CSV while Excel might freeze and work with a lightweight shell gets me what I need.
Why is it called the shell? The important part is the actually because it functions in the center of the system.
It's called the shell since around the curve, it's just like a car where the steering wheels and pedals dashboards, giving you control of the engine or transmission, all existing to show the current lowest level access to software functionality that comes with an operating system. Many of the most useful tools don't have a graphical interface.
Master the command line expands your arsenal and lets you get more done with less they let you be able to use scripting and automation to tackle repetitive tasks that would otherwise be wasted. automating your workflow on the command line makes you a tremendously valuable asset to the team. I recommend starting out with bash or to get shell since it comes default with almost every Linux distribution that is used in in its terminal app has since changed to Z shores the show and has some nicer features in Bash is like a Toyota Z. She's more like Alexis Bash is so awkward and effective that Microsoft actually the windows subsystem for Linux WsL lets you install several different Linux flavors to use bash.
This is super convenient if I can access all 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 how you will 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 going to start a series on the Linux command line. Comment below to let me know what tools and concepts you have.
Number three, System Administration. All of us with the computers at wizard is really a sysadmin at some level, it all depends on what level your system administration involves configuring and maintaining a computer, whether a personal device or high powered server when I was first using computers as a kid, I love to dive down into every single setting available on the computer just to see what it did. Reading manuals, online guides and playing around, drove this curiosity further by doing that I became the family it helped them. This administration is about knowing your platform in various tools. To be able to help others who don't have their skill. I challenge you to fiddle around, delete some files and try to recover them. Download open and monitor old viruses and virtual machine with tools like Windows System internals to try to extract files without building a login, whatever it is push the limits of what you already know by reading guides up there and following the practice a little more each day and you will love love.
4...Number four: computer networking. This is the heart and soul of what I like to call the cyber spatial laws of physics is understanding how devices interact with each other and how data gets from point A to point B. The strong foundation in networking will make you a rockstar troubleshooter, whether you're red teaming, defending running day to day it honestly there's two separate models TCP IP and OSI the group all your different networking and telecommunication protocols into layers. TCP IP is older and more layers network access internet transport layer. OSI stands for the open system interconnection which is developed by the International Organization for Standardization or ISO. These guys defined everything country codes to time and date formats.
Newer uses seven layers, physical data link, network, transport, session, presentation and application. 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 addresses. And operating with a post office tells you there's an airline issue, you know where it is the transportation system that's delaying your delivery. Likewise, networking layers all have different functions as a whole together until a new stream videos from the server and a rack to a device in your hands. Knowing what's happening at each layer. lets you see the matrix will be much more skilled than crap.
Number five, personal digital security. This is an area I've been particularly passionate about as it affects our families, friends and organizations. The cybercrime industry.
You don't have to grow far to see what the online black marketplace looks like. As technology becomes more intertwined with our lives from the intersection of the guards to refrigerators, the vulnerabilities and attack vectors.
You want to go deep into cybersecurity. There's no better place to start yourself from passwords and encryption to secure and stay up to date with the latest security news and best practices. You might just be the subject matter expert more often than 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. You wouldn't believe the number of times I've seen cyber intrusions originate from the security operations or IT departments simply because people didn't understand who practice basic digital hygiene. So that's it for this video.
Thanks so much for tuning in.
