Projects

• Network Intrusion Prevention System (Adaptive Firewall)
  Python, Kali Linux, iptables

  Developed a Python-based adaptive firewall to detect SSH brute-force activity through continuous log monitoring. Automated malicious IP blocking using iptables and implemented configurable auto-unblocking. Logged security events to support auditability, investigation, and incident analysis.

• An Integrated Framework for Climate Data Anomaly Detection and Image Tampering Verification
  SHA-256, Isolation Forest

  Verified satellite image integrity using SHA-256 hashing and metadata analysis to detect tampering and manipulated images. Applied the Isolation Forest algorithm to flag anomalies in climate datasets, combining it with the tamper-detection layer into one pipeline.

• SIEM Threat Detection Lab
  Wazuh, Linux, Nmap

  Built a hands-on SOC lab using Wazuh SIEM on virtual machines for centralized log collection and security monitoring. Simulated SSH brute-force attacks and Nmap reconnaissance to generate attack telemetry and security events. Created custom Wazuh detection rules to identify repeated authentication failures and generate security alerts.
