Required Cybersecurity Skill: Understanding Basic Networking Concepts

[@Root-uno6nw]

From my understanding of what you need to for networking for cybersecurity or security operations standpoint is the deployment of routers and switches, firewalls, SIEMs, NIDS, HIDS and network taps. How you set them up, placement or positioning of them , how they work within a business enviroment. This then raises the question how do you go about securing this business private LAN from the external network ? The deployment of HIPS, NIDS, or Stateful and Stateless firewalls and can you audit the network and identify any open ports using basic pentesting tools and understand their output alongside understanding of endpoint protection and soild of understanding of network traffic. Once you can understood this your pretty much nearly there.

It’s always funny to listen to someone with so much knowledge trying to explain/teach it to others. It’s so much harder than some think. Like when I’m trying to teach my kid how to do a certain math problem, I’m like yeah it’s easy and then trying to break it down in learning terms is so much harder in some instances and making it understandable.

In Q4 2023, I was laid off. My search for a new career path began and I chose the fantastic path of Cybersecurity which I had been tapping at a personal level for years. But as a manager, you tend to focus your attention to other aspects of the business and I want to move to a more technical area. Why I am saying this? What Gerry is saying is absolutely true. You need to understand how systems interconnect. I did my post graduate degree in 1999, yes a year before the big Y2K buzz and I created a router as one of my projects. I wish I could go back in time and grab that brain and bring it to the present. Oh how I miss that brain, 😂.

[@chrisr4715]

So would you say that having the N+ or CCNA is too much if we don't want to go specifically into networking? I know the basics of the OSI model as you mentioned in the video but how will employers know that I know that without seeing something network cert related on my resume? Should I just go for the S+ instead? Thank you so much for providing all this knowledge btw. I've been in IT application support for at least 8 years now but I want to move up and have a specialty besides app support.

[@SimplyCyber]

N+ would be fine. CCNA is a harder examine, more hands on the tech itself and is specialized to cisco hardware. A good chunk of the exam is actually configuring virtualized cisco network routers. Really nothing to do with direct security there. I wouldnt invest time/money in CCNA unless you were going to be very hands on network security person (working at a Ciscoshop business). Sec+ is where I'd start. Alot of people will say get networking+ first than security but i didnt and I was fine ( I have a cmpsci bg though so your exp may differ). Having said all that, the N+ cert wont do much for you other than convey to interviewers that you should know networking concepts. Actually knowing them and folding them into your responses (and your actual work) is where the value shines. Best wishes/

[@SimplyCyber]

i have / had (dont maintain it) CCNA. I dont think its needed for infosec. CCNA is super focused on how cisco networks work, and while you do learn about different routing and resiliency and such, i think you can get more value puttting your time elsewhere, sepcially if you have network+.

[@SimplyCyber]

It really depends on your career goals and urgency for money. College degree should give you a more grounded, wider exposure to the field, but costs money/takes time. It will help long term, but if you get certs and compliment your resume with labs you should be able to get access to the same opportunities. There is a great cert chart here that can help you zero in on certs that apply to where you want to go: pauljerimy.com/security-certification-roadmap/

[@ahmadirfan7840]

I am a software developer and i am really interested and have ambition to get a job in cybersecurity especially in ethical hacking. I have studied about general networking stuff, such as WAN, LAN, TCP/IP. If I’m not mistaken, I also taught about to calculate the subnet but until now, I still confuse about it. I also have a background in programming and among of it, I am more comfortable to Python and sometimes I quite struggle for some Python basic, I can reached out to the documentation. But since I only want to know, or to be honest, to re-study the networking basic, is it enough for me to have these foundation and start playing around with the tools such as nmap, wireshark, then start to apply the job in the cybersecurity roles?

I have a passion in the networking field but little worried about the future. Please clear this.

AI will help make our ability to respond faster, but wont replace humans. Threat actors are humans and they can be clever and trick tooling. Humans will use tooling (and AI) to be more efficient and timely in response.
