Day 4 of my Linux for SOC journey, and I'm humbled.

I thought "learning Linux" meant memorizing commands.

Today I learned it means:
1. Staying calm when `kill` fails and finding `killall`
2. Not giving up when the network blocks you `wget` through it
3. Building redundancy, Kali VM + Termux on phone = never offline

Thank you to everyone sharing resources. Special shoutout to the SOC community for normalizing the struggle.

If you're on Day 1 and seeing `permission denied`, keep going. Day 4 feels different.

Open to feedback from current SOC analysts. What should I tackle Day 5?

Day 3 of Linux, question for my tech people:

If your SIEM says "Malware detected" but Wireshark shows the file downloaded was logo.gif...
Is it false positive or smart hacker? 🤔

Learning packet analysis today for Cybersecurity prep.
Turns out "hacking" is 10% cool tools, 90% reading logs nobody wants to read.

Drop your best Wireshark filter below. Let’s grow together.

Day 2 of my Linux journey 💻🐧

Today I learned to actually TALK to my computer:
✅ pwd = "where am I?"
✅ ls / ls -la = "what's here + show hidden files"
✅ mkdir / touch = create folders & files
✅ cp / mv / cat = copy, move, read stuff
✅ rm = delete... and yeah no recycle bin 😅

I broke stuff on purpose just to learn how to fix it. That’s the cyber mindset.

Stage 1: Beginner loading... 20% complete
Next: sudo + permissions = where the real hacking begins

making money is very hard nowadays compared to 1980😩

Most people use security after something breaks.

The best engineers build systems that are secured by default.
