I am an aspiring cybersecurity professional with hands-on experience in threat detection, malware analysis, and security automation. As a Google Cybersecurity Certificate holder, scholarship recipient, and active Capture The Flag (CTF) participant, I have built a strong foundation in network security, endpoint protection, incident response, and ethical hacking.

I leverage my technical skills in Python, SIEM concepts, file integrity monitoring, and malware detection, along with strong analytical and problem-solving abilities, to protect organizations and strengthen digital infrastructures. I actively pursue continuous learning to stay ahead of emerging cybersecurity challenges and contribute to resilient and secure digital environments.

Uriel SysGuard is a Python-based File Integrity Monitoring (FIM) and threat detection tool designed to help security analysts detect unauthorized file changes and potential malicious activity on a system. The project applies real-world defensive security concepts commonly used in SOC, DFIR, and SIEM environments.

File integrity monitoring is a critical security control used to detect:

• Unauthorized file modifications
• Malware persistence techniques
• Insider threats
• System compromise indicators

• 🔐 File Integrity Monitoring (SHA-256 / SHA-3)
• 🧬 Change Detection for files and directories
• 🦠 YARA Rule Integration for malware/pattern detection
• 📊 Security-Oriented Logging
• 🔄 Designed for future SIEM integration (Wazuh, Sysmon)

• Defensive cybersecurity principles
• DFIR
• Cryptographic hashing
• Malware detection with YARA
• Python scripting & automation
• Host-based security monitoring
• Log analysis fundamentals

1. Selected files/directories are monitored
2. Cryptographic hashes are generated and stored
3. Files are periodically re-hashed
4. Any hash mismatch triggers an alert
5. YARA rules are applied to detect malicious patterns
6. Events are logged for analysis or escalation
