I put together a complete CCNA in 8 Weeks roadmap and decided to make it free for everyone. If you're preparing for the CCNA or want to become a Junior Network Engineer, this guide gives you a structured path instead of guessing what to study next. 🧵

Day 8 Malware today, and the list looked like pure memorisation until I saw what the categories actually are 👇

I build vulnerable apps on purpose. It made me a better defender than any detection course did 👇

A home lab isn't a production SOC. I know that. That's why I'm building mine to resemble a real corporate environment as closely as possible. 🧵

🛡️ 28-day SOC build. In public. No filler. Every project here is a detection I wrote or an incident I walked end-to-end not a tutorial replay. 🔍 Splunk · SIEM · Log Analysis 🧠 MITRE ATT&CK · Threat Detection 💻 Kali · Ubuntu · Windows home lab 📜 ISC2 CC This is what hire-ready looks like 👇

30-Day Cybersecurity Learning Journey OverTheWire Bandit CTF Documentation (Day 1–10) 𝗧𝗵𝗿𝗲𝗮𝗱 🧵 1/ 𝗢𝘃𝗲𝗿𝗧𝗵𝗲𝗪𝗶𝗿𝗲 𝗕𝗮𝗻𝗱𝗶𝘁 – 𝗟𝗲𝘃𝗲𝗹 0 → 1 (𝗗𝗮𝘆 1) I started my cybersecurity learning journey by exploring the Bandit wargame.

𝗗𝗮𝗶𝗹𝘆 𝗖𝗧𝗙 𝗗𝗶𝘀𝗰𝗶𝗽𝗹𝗶𝗻𝗲 ~ 𝗢𝘃𝗲𝗿𝗧𝗵𝗲𝗪𝗶𝗿𝗲 𝗝𝗼𝘂𝗿𝗻𝗲𝘆 Real technical skill isn’t built in bursts. It’s built through consistency. I’ve committed to 30 minutes every day to complete one OverTheWire level until I finish the entire series. The goal isn’t just solving challenges.

🔅 Easily Find a File in Linux Looking for a specific file on your Linux system? 🧐 Use this command: find / -name "filename" This searches the entire system for your file. 🔍

𝗧𝗵𝗲 𝗦𝗨𝗦𝗣𝗜𝗖𝗜𝗢𝗨𝗦 𝗡𝗲𝘁𝘄𝗼𝗿𝗸 𝗙𝗹𝗼𝘄 – 𝗗𝗲𝗰𝗲𝗺𝗯𝗲𝗿 𝟵, 𝟮𝟬𝟮𝟱 SOC network logs showed one device sending unusual traffic to a rarely used external IP. Investigation revealed malware beaconing for C2 communication. Immediate containment stopped lateral movement and prevented data theft.

🚨𝗥𝗮𝗻𝘀𝗼𝗺𝘄𝗮𝗿𝗲 𝗕𝗲𝗵𝗮𝘃𝗶𝗼𝗿 𝗟𝗮𝗯 (𝗕𝗲𝗴𝗶𝗻𝗻𝗲𝗿 𝗦𝗢𝗖) Ransomware isn’t just malware. It’s patterns. In a controlled lab I simulated: • Mass file changes • AES encryption • Files renamed to .locked • A ransom note dropped

🚨 Beginner SOC Lab: Catching Sneaky Access I built a small home lab to practice as a SOC analyst. Setup: • Windows 11 VM (victim) • Kali Linux VM (attacker) • Shared “HR” folder with a Canarytoken inside Simulated an attack: • Found the SMB share • Opened files • Triggered the Canarytoken

"HOW A WI-FI ROUTER WORKS"

I BET YOU DONT PAY ATTENTION TO THIS LITTLE THINGS ‼️

If a hacker gain access into your system this is what they search for first

𝗟𝗮𝘁𝗲𝗿𝗮𝗹 𝗠𝗼𝘃𝗲𝗺𝗲𝗻𝘁 & 𝗣𝗲𝗿𝘀𝗶𝘀𝘁𝗲𝗻𝗰𝗲 Lateral movement = breaking into one system, then sneaking into others using stolen creds or tools. Persistence = staying hidden with auto-start programs or fake accounts. SOC teams hunt this using logs + smart detection rules 🛡️

File System Comparison

Common Mistakes Smart People Make •Reusing passwords •Over-trusting biometrics •Installing too many browser extensions •Ignoring firmware updates •Thinking antivirus = full protection Security is discipline, not tools.

The seven layers of the OSI model include: 1. The Physical layer 2. The Data Link layer 3. The Network layer 4. The Transport layer 5. The Session layer 6. The Presentation layer 6. The Application layer

Today I finished setting up my SOC lab on Kali Linux, and what a learning experience! 🎯 I created a dedicated lab user socuser, disabled command history, turned off unnecessary services, and separated lab browsing from personal browsing.

Stop Confusing Bus, Star & Ring Topologies (Simple Guide)

No one knows the effort that went into your work more than you. Don’t wait for others to acknowledge your efforts.

Monthly Milestones Month 1 •Understand networking basics •Comfortable in Linux terminal Month 2 •50+ TryHackMe rooms completed •Security+ 50% complete Month 3 •Book Security+ exam •Build basic home lab Month 4–6 •Apply for IT/SOC roles aggressively

Package cleanup 1️⃣ apt autoremove – remove unused 2️⃣ apt clean – clear cache 3️⃣ dpkg -l – list packages 4️⃣ dpkg -r – remove package 5️⃣ apt purge – remove configs too Keep your system clean & fast. Which one would you run today?

The fastest way to stand out in IT? Become the person who documents everything you learn. New tool, new command, weird server issue? Write it down. Your notes become your superpower. Nobody remembers everything. Pros build knowledge gardens.

Nobody talks about IT audit roles. You're verifying companies follow security policies and checking compliance frameworks. Pays $60K-$80K entry level. You don't need to be as technical, just detail-oriented. Google "IT auditor" or "GRC analyst" on Indeed.

Recruiters screen for risk. Hiring managers screen for fit. Your application needs to satisfy both.

Success isn't about being the best. It's about refusing to quit.
