Projects

Cybersecurity Knowledge Base (Project lead)

Personal project

Summary

Created and maintained a shared Google Drive repository containing links to software downloads, guides, troubleshooting commands, and other documentation. Aimed at improving peer learning, onboarding efficiency, and hands-on practice at Altschool Africa.

Elastic SIEM SOC Deployment & Detection Engineering
Elastic SIEM SOC Deployment & Detection Engineering

Summary

Designed and implemented a cloud-based security monitoring solution using AWS and Elastic SIEM to detect IAM privilege abuse, SSH attacks, and malicious IP traffic, integrating threat intelligence (AlienVault OTX) for IOC enrichment and performing endpoint investigations.

Secure Communication and PKI lab
Secure Communication and PKI lab

School Project

Summary

Organizations rely on TLS and PKI to secure communications, but misconfigured certificates, weak keys, or poor protocols can compromise security. This project explored how secure channels are established, verified, and tested, implementing a PKI-based environment with TLS 1.3, mutual authentication, and hardened SSH, validated through traffic analysis and controlled vulnerability testing.

Log Integration
Log Integration

Summary

Many organizations use cloud-managed endpoint security platforms like Sophos Central but lack centralized SIEM visibility due to licensing or deployment constraints. This project addressed that gap by designing a practical SIEM integration that reliably extracts, validates, and analyzes Sophos security events without relying on traditional syslog or on-prem setups. The project evaluated multiple SIEM options and demonstrated integration with Wazuh Cloud to enable centralized monitoring, event analysis, dashboards, and alerting under real-world constraints.

Enterprise WAN simulation
