and from there, that's what we're gonna have to talk about on Cysts Systems Administration. Like I said, uh, we're actually building out that career path. Sort of. As we go through these videos, you're gonna get to see some of this. Get included for that as the class continues.
Also, I'm gonna hand this back off to my partner in crime was gonna tell you all about the exciting, wonderful world being a network engineer, right? I'm super excited.
All right, So network engineering a CZ as you may or may not know, network is basically, you know what? All of your company's computers are running off, right? So there's a network in place whether you know it or not. But that's how you access things like the Internet and do your Google searches and look a cat videos on YouTube like someone I know. So that's that's the underlying architecture.
So with network engineering, it's kind of that next step
over a sys admin. So you know, a lot of people start out and they help disk, as Joe mentioned on, and then sort of the next vertical as they're getting Maur experience with different systems across the organization, they'll generally jump into, like network engineering. And so some of the sort team mentioned the starting off point. So, like network plus and stuff, we'll talk about that a little later on.
But what do network engineers to right? What is this kind of their main responsibility?
So they're responsible for actually building, maintaining and helping to protect the network. So
with the maintenance aspect of that, you know, you might get different requirements coming in across the organization of saying, Well, we need to put this new application and we have this new team we're developing. How do we How do we set them up with computers, Right. How did they get access to things? So as a network engineer, you kind of architect, all that build that stuff out, map it out essentially
and then helped build it out with your team.
And then from there you have it actually protected, right? Because criminal hackers are always trying to get in, and so we have to protect those network. So some of the things you'll do as I mentioned, you'll analyze the design and requirement documents, so that's gonna come from different apartments. Could be from like the CEO could just being from the accounting team, a lot of different people will be
bringing in new things for you to do.
You're also gonna be mapping out the network architecture, so ah, lot of a lot of your weekly top of jobs or even on a monthly basis. With that, we'll talk about that a little later also. But a lot of that's just building out different network diagrams of showing like, What's the current state of the network? Where are different, you know, firewalls, routers, which is where they on the network and then presenting that
generally in the C suite or just to your like your I T manager
and then also, you know, operating everything is well, right. So we're operating hardware operating software. We're also operating in,
you know, networks. Nowadays, we're operating a lot of virtual machines as well to help distribute the band with so we can keep systems up and running at a lower cost.
So some of the key skills that you're gonna need abilities reporting a communication and you'll notice throughout our presentation today that we kind of list those of the top two, mostly because it doesn't matter how good you are. Yours, your job. If you can't convey that to you like your manager or you know his or her manager or anyone else in the organization,
it's kind of pointless, right, because it is difficult for you to then
get funding and do other things that you need to do to be more efficient in your job. So reporting communication are always going to be at the top of the list, and along with customer service skills as well, it's really just about how you present yourself and whatever information you're trying to present.
It never matters. If you are successful, you can't communicate what is successful about exactly exactly. You know, if if we sit there and we stumble or if we can't say, Hey, I found all these issues with the network,
then the CEO is going to say, Well, I'm not gonna give you more money in the budget because I don't understand why you need it right. I don't understand why you need a new firewall or why we need more routers and switches, etcetera. So yeah, absolutely. You know, it's very, very important to communicate things effectively.
Also operating network equipment. That's a skill you're gonna. You know, of course, that's a learned skill, you know, dealing with different networking concepts, protocols, you know, like T c P i. P. Different. Dealing with the always model. Again, we'll cover all that in a later section of this particular training course. Different working security methodologies. You know, eso.
Once you start working at industry or a cz your training into the industry, you'll hear
defence in depth. You'll hear defense in depth, somewhat overused but key concept, yet lots of use. But the key concept is appropriate, right? Like we want to put different thing obstacles essentially in place where the criminals can't get it right. So think about it like if you go to the grocery store
and you know they got
different barriers in front of the store to keep you, you know, keep you know, someone from driving into the store with her car. That's to keep you from getting in and hurting somebody, right? So think of it the same way with your network. We put these little barriers in place to try to prevent the quantum hold bad people from breaking into stuff and hurting everybody.
You're also gonna be analyzing network traffic as a network engineer. So that's gonna be a huge chunk of your day to day operations. Is just analyzing all the information that's coming in from different devices on your network and making sense of it, Hopefully on. Then again, going back to the reporting aspect, generating reports so you can share that information with others,
as I mentioned protecting the networks. And then, of course, depending upon where you're located, your company
or you yourself, there's different laws, regulations and standards that you'll have to follow. So, for example, if your company's in health care, you'll have to follow things like hip A in high tech. Don't worry about those too much. We'll touch on those a little bit more in the actual course sessions. A CZ Well, it's like if you're in the financial industry, you know things like the Gramm Leach Bliley act here in the United States.
A zealous, you know, things like socks.
PC idea says Standard. So there's a lot of things, and it depends on your particular company what you're you have to worry about. Just keep that in mind that there's a lot of information you'll have to know about us. A network engineer to be more efficient. No, of course you know, with enterprise companies and some mid level cos you'll have people like attorneys on staff
Andi compliance folks that will handle some of that.
However, it's better if you have an understanding of these different regulations as well, so that we can implement changes and be more of a brand ambassador off the networking side to make sure the organization's doing what I should.
