I got fired from my position few weeks ago, as a Network Security Engineer thanks to AI.
It was a bummer. It took me days to wonder whether all those hours spent studying networking, security, incident handling, firewall, and everything else would go to waste.
But then I dug up my old notes.
They contained years of experience earned the hard way through mistakes, incidents, tools, tricks, and experience that is not covered by any certification.
And instead of storing them all on my laptop, I decided to publish all of this stuff right here.
Maybe it will help someone to find a job or solve some problems or simply learn something new.

@levelsio This is where I wish @elonmusk would fix the algo...
- Negative: 230M views / 217 posts = ~1.06M views per post
- Positive: 148.4M views / 346 posts = ~429K views per post
So negative posts average about 2.5x more views per post than positive posts.
Less than 15 days.

I’m grateful to everyone who decided to follow my journey.
I’ve been sharing content focused on network security, cybersecurity, and what I’m learning every day. It’s a small milestone, but it’s a reminder that consistency matters more than chasing numbers.
Thanks for being here. Plenty more network security content is on the way. 🔐

I decided to turn everything I learned as a Network Security Engineer into a free, public series.
No paywall. No course. Just one lesson at a time.
I just published Day 1: What is Cybersecurity?
If you’re new to cybersecurity or want to revisit the fundamentals, this series starts from absolute zero and builds toward real-world security engineering.
Bookmark the thread if you want to follow along.
👇 Day 1 is below.
Day 1/30
What is Cybersecurity?
Cybersecurity is the practice of protecting computers, networks, applications, and data from unauthorized access, attacks, and damage.
Think of it like securing a house.
Your house = Computer or Network
Doors & locks = Authentication
Security cameras = Monitoring
Alarm system = Detection
Security guard = Incident Response
The goal isn’t to stop every attack.
The goal is to reduce risk, detect threats early, respond quickly, and recover with minimal damage.
Over the next 30 days, we’ll build a strong foundation in Network Security Engineering and Cybersecurity one lesson at a time.
Tomorrow: How the Internet Works.
