🔐 My Cybersecurity Learning Journey: PowerShell, Python & Bash — Day 3

NANGYSEC — Sun, 16 Aug 2026 12:10:57 GMT

📚 My Cybersecurity Learning Journey — Day 3 Yesterday was another productive day of learning and hands-on practice. I spent time working with three important technologies: 🔹 PowerShell — learning how to interact with and inspect Windows systems using commands. 🔹 Python — continuing with programming fundamentals and building a stronger foundation for future cybersecurity automation. 🔹 Bash — practicing Linux navigation, file management, and redirection using commands such as cat, echo, >, and >>. I'm beginning to understand how these tools connect to cybersecurity. PowerShell is valuable for Windows environments, Bash is essential for Linux environments, and Python can help with automation and scripting. I'm documenting my progress as I learn, practice, make mistakes, and improve. The journey is just beginning. 🔐🐧🐍💻 #Cybersecurity #Python #PowerShell #Bash #Linux #CybersecurityLearning #EthicalHacking #NANGYSEC

Article Title: My First Practical Windows Log Analysis Lab

NANGYSEC — Fri, 14 Aug 2026 17:55:34 GMT

Today I continued my cybersecurity learning journey by diving into Windows logs and practical log analysis using Event Viewer. Instead of just reading about logs, I wanted to understand what actually happens on a Windows machine when someone successfully logs in or enters the wrong password. 🔍 What I Practiced I started by navigating through: Event Viewer → Windows Logs → Security I learned how to filter the Security log using specific Event IDs and then investigate individual events. 🔐 Event ID 4625 — Failed Logon I investigated a real 4625 event from my own Windows machine. The event showed: Event ID: 4625 Logon Type: 2 Target Username: NANGY Status: 0xc000006d SubStatus: 0xc000006a IP Address: 127.0.0.1 By examining the event's XML data, I learned that the authentication attempt failed because of an incorrect password. I also learned that 127.0.0.1 is the loopback address, meaning the activity originated from the local computer. ✅ Event ID 4624 — Successful Logon I then investigated a successful logon event. The event showed: Event ID: 4624 Target Username: SYSTEM Target Domain: NT Logon Type: 5 IP Address: - This helped me understand that not every 4624 event represents a person manually logging into Windows. Logon Type 5 represents a service logon, which can occur when Windows services authenticate under an account such as SYSTEM. 🧩 Understanding XML View One of the most useful things I learned today was how to use: Details → XML View The General tab gives a simplified explanation of an event, while XML View exposes structured event data such as: TargetUserName TargetDomainName Status SubStatus LogonType IpAddress LogonId This helped me move beyond simply seeing an Event ID and start asking: Who? What happened? When? Where did it come from? Why did it happen? 🧠 What I Learned About Log Analysis Today's biggest lesson was that one Event ID doesn't automatically tell you whether something is malicious. For example, seeing multiple 4625 events could mean something as simple as someone entering the wrong password, or it could potentially be part of a larger pattern such as brute-force or password-spraying activity. The important thing is to examine the context and surrounding evidence. My approach is becoming: Event → Evidence → Context → Conclusion 🚀 What's Next? I'm stopping today's practical session at Event ID 4688 — Process Creation. Next, I'll investigate which processes are being created on Windows, what launched them, and how process-creation logs can help with security investigations. I'm still at the beginning of my cybersecurity journey, but every lab is helping me understand how real security investigations work. One lab at a time. One concept at a time. One step closer. 🔐💻 #CyberSecurity #Windows #EventViewer #LogAnalysis #SOCAnalyst #BlueTeam #InfoSec #CyberSecurityJourney #LearningInPublic #NANGYSEC

My First Hands-On Linux Lab for Cybersecurity | NANGYSEC 🔐🐧

NANGYSEC — Thu, 13 Aug 2026 09:19:22 GMT

Another day of building my cybersecurity fundamentals 🔐 Today I started getting more comfortable with the Linux command line using my Kali Linux virtual machine. I practiced essential commands such as: cd — navigating directories pwd — checking my current directory ls — viewing files and directories mkdir — creating directories touch — creating files These are basic commands, but they form part of the foundation for working with Linux systems and eventually performing more advanced cybersecurity tasks. I’m documenting my progress as I learn, practice, make mistakes, and improve. This is only the beginning of my cybersecurity journey. 🚀 #Cybersecurity #Linux #KaliLinux #Bash #CybersecurityLearning #InfoSec #EthicalHacking #LearningInPublic

Starting My Cybersecurity Journey: From the Fundamentals to Hands On labs

NANGYSEC — Wed, 12 Aug 2026 10:40:19 GMT

Hi everyone! 👋

I'm starting my cybersecurity journey from the ground up, and I've decided to document my progress here on NANGYSEC.

I'm not an expert yet. I'm still a beginner, and that's exactly why I decided to start this blog — to learn in public, document my progress, and share what I discover along the way. 🔐 Why I Chose Cybersecurity I've always been interested in computers and technology, but cybersecurity really caught my attention because of how much there is to understand. I want to learn how computers, networks, operating systems, and security tools work — and eventually be able to use that knowledge to solve real security problems. I know becoming good at cybersecurity won't happen overnight. There is a lot to learn, and I'm prepared to start with the fundamentals and build from there. 💻 What I'm Learning I'm currently working on the foundations of cybersecurity, including: 🌐 Networking fundamentals 🐧 Linux 🪟 Windows ⚡ PowerShell 🐍 Python 🖥️ Bash 🔐 Cybersecurity fundamentals 📁 File systems 📊 Logs and system monitoring 🕵️ Digital forensics 🧪 Hands-on cybersecurity labs I'm also learning how different security concepts connect together instead of just memorizing definitions. 🧪 My Hands-On Learning One thing I've realized is that cybersecurity isn't something I want to learn only from reading. I want to actually practice. I've started setting up a small home lab using virtual machines so I can experiment in a controlled environment. For example, I'm learning how to work with Kali Linux, explore Linux commands, understand networking, investigate system information, and eventually perform more security-focused exercises. My goal is to take what I learn and turn it into practical projects that I can document here and on my GitHub. 📚 Learning in Public I'm starting this blog because I want to document the journey — including the things I don't understand at first. Sometimes I'll probably get something wrong. Sometimes I'll spend hours trying to understand something that seems simple to someone more experienced. And that's okay. I believe documenting the process will help me understand things better and allow me to look back later and see how much I've improved. 🎯 Where I Want This Journey to Take Me My long-term goal is to become highly skilled in cybersecurity and eventually work on real-world security problems. I'm particularly interested in areas such as digital forensics, incident response, and cloud security, but for now I'm focusing on building a strong foundation. Before I try to run, I want to learn how to walk. That means understanding the fundamentals first: Computer → Operating System → Networking → Security → Programming → Practical Labs → Real-World Skills 🚀 What's Next? This is just the beginning of my journey. In future posts, I'll be sharing things such as: What I'm learning each week Cybersecurity concepts explained from a beginner's perspective Linux and PowerShell practice Python learning progress Home lab experiments Cybersecurity projects Digital forensics experiments Mistakes I've made and what I learned from them If you're also learning cybersecurity, feel free to follow along. And if you're already working in cybersecurity, I'd genuinely appreciate any advice or lessons you think could help someone starting from the fundamentals. I'm here to learn. This is Day 1 of my cybersecurity journey. 🔐🚀 Welcome to NANGYSEC.
