Hi, I'm Ugochukwu 👋

🔐 SOC Analyst | Network Security & Incident Response | SIEM | Linux Security | Threat Detection | Blue Team Projects

I build practical blue-team Security labs focused on real-world attack detection, log analysis, and security monitoring automation. My work centers on understanding how attacks appear in logs and building detection techniques used by modern Security Operations Centers (SOC). Open to Cybersecurity collaboration and international opportunities.


🛠 Technical Focus

  • Linux system log analysis (auth.log)
  • SSH brute-force detection
  • Bash scripting & automation
  • Threshold-based alerting
  • Cron job scheduling
  • Basic malware analysis (Kali Linux)

💻 Tech Stack

  • Linux (Ubuntu/Kali)
  • Bash
  • grep / awk / sort / uniq
  • Cron
  • Git & GitHub
  • Basic Networking (SSH, TCP/IP)

🚨 Featured Projects

🔎 SSH Brute-Force-Detection-Splunk

Detection and analysis of SSH brute-force attacks using Splunk SIEM, log ingestion, attack simulation, and correlation of failed and successful login events.

  • splunk
  • siem
  • brute-force
  • log-analysis
  • threat-detection

➡️ Repository: https://github.com/Ug111/ssh-brute-force-detection-splunk


🔎 SSH Brute-Force Live Monitoring

Real-time SSH attack detection system using Bash and log parsing.

  • Dynamic IP extraction using awk
  • Threshold-based alert alerts
  • Persistent logging
  • Cron automation

➡️ Repository:

🧪 SSH Log Investigation

Manual investigation of suspicious login attempts using Linux command-line tools.

  • grep filtering
  • Failed login pattern analysis
  • Attack source identification

➡️ Repository:
https://github.com/Ug111/linux-ssh-log-investigation


🦠 Malware Analysis (Kali Linux)

Static malware inspection in a controlled lab environment.

  • File hashing
  • Strings analysis
  • Basic reverse inspection techniques

➡️ Repository:
https://github.com/Ug111/Kali-malware-analysis


🎯 Career Objectives

I am a SOC Analyst with hands-on experience in threat detection, log analysis, network security, Linux, and Hack The Box labs. I am actively seeking an entry-level SOC Analyst or Cybersecurity Analyst role where i can contribute to security operations while continuing to grow more technical expertise.


Long-Term Vision

My goal is to bridge the gap between technical cybersecurity and business strategy and also the intersection of cybersecurity operations and policy specifically within the African digital economy context. Nigerian's critical infrastructure, banking, telecoms, energy is increasingly digitised and highly targeted While building my career as a SOC Analyst, i am also developing a cybersecurity consulting brand that helps startups and small businesses:

  • Reduce cyber risk
  • Improve security awareness
  • Understand compliance requirements (NIST, SOC 2, GDPR, ISO 27001)
  • Protect customer trust and business revenue
