5 years ago, I stepped into the cybersecurity world with more questions than answers. I didn’t have it all figured out. What I did have was curiosity, a background in mathematical cryptography and a willingness to learn things the hard way.
Today, I’ve:
- Handled countless cybersecurity incidents
- Managed cybersecurity operations for over 20 clients across various industries
- Turned my experience into knowledge that I now share freely on LinkedIn
I started sharing because I remember how lonely the journey felt in the beginning. There were so many technical terms, tools, and expectations. Also not enough people simplifying it.
That’s why you’ll find me dropping PDF guides, real scenario simulations, alert triaging walk-throughs, and practical advice especially for those in SOC analyst roles. No fluff. No buzzwords. Just honest insights I wish I had when I started.
I’ve also compiled my knowledge into a book for future analysts:
“Mastering Cybersecurity Analysis”

You Should Know:
Essential Cybersecurity Commands & Tools
1. Network Scanning with Nmap
nmap -sV -A target_IP
– -sV: Service version detection
– -A: Aggressive scan (OS detection, script scanning)
2. Log Analysis with Grep (Linux)
grep "Failed password" /var/log/auth.log
– Check for brute-force attacks in authentication logs.
3. Windows Event Log Analysis
Get-WinEvent -LogName Security | Where-Object {$_.ID -eq 4625}
– Filters failed login attempts (Event ID 4625).
4. Malware Analysis with Strings
strings suspicious_file.exe | grep "http|https"
– Extracts URLs from a binary file.
5. SIEM Query (Example: Splunk)
index=security sourcetype=firewall action=blocked | stats count by src_ip
– Lists blocked IPs from firewall logs.
6. Incident Response: Memory Dump (Windows)
winpmem.exe -o memory_dump.raw
– Captures RAM for forensic analysis.
7. Linux Hardening (Disable Unused Services)
sudo systemctl disable telnet
8. Encrypting Files with OpenSSL
openssl enc -aes-256-cbc -salt -in file.txt -out file.enc
9. Detecting Open Ports (Windows)
Test-NetConnection -ComputerName target_IP -Port 80
10. YARA Rule for Malware Detection
rule Detect_Ransomware {
strings:
$ransom_note = "Your files are encrypted"
condition:
$ransom_note
}
What Undercode Say
Cybersecurity is a continuous learning journey. Mastering tools like Nmap, Splunk, and YARA accelerates threat detection. Always verify logs, automate repetitive tasks, and stay updated with MITRE ATT&CK frameworks. Practice in labs (TryHackMe, Hack The Box) and document your findings.
Expected Output:
A structured cybersecurity guide with actionable commands for analysts.
