📖
Security Automation

Automated SOC Threat Intelligence Platform with Real-Time SIEM Integration

Built a Python/Nmap/Burp Suite/SQLMap scanning platform targeting OWASP Top 10 vulnerabilities; integrated ELK Stack for real-time threat dashboards — replicating enterprise SIEM and security monitoring workflows.

📖
Security Product Development

Multi-Modal Voice Biometric Authentication & Real-Time Spoofing Detection

Engineered a privacy-preserving security product using federated learning; conducted adversarial threat modelling to evaluate and harden system resilience with multi-modal authentication.

📖
SIEM & Threat Detection

Wazuh SIEM: SSH Brute-Force Detection Lab

Built a Wazuh SIEM lab using Wazuh OVA, Kali Linux, and Ubuntu to detect SSH brute-force activity. Configured Kali as a monitored endpoint with the Wazuh Agent and used Ubuntu to generate SSH password-guessing attempts with Hydra. Investigated alerts in Wazuh Threat Hunting, validated evidence using /var/log/auth.log, identified source IP and target user details, and mapped the activity to MITRE ATT&CK Credential Access / Brute Force. Documented the incident with SOC-style findings, severity, evidence, and remediation recommendations.

📖
SOC Analysis & Threat Investigation

Phishing Email Analysis & IOC Extraction Lab

Performed a SOC-style phishing email investigation using Kali Linux by analyzing suspicious email content, reviewing email headers, extracting IOCs such as sender email, reply-to address, URLs, domains, and IP addresses, and validating phishing indicators including SPF failure, missing DKIM, DMARC failure, Reply-To mismatch, typosquatting, and urgency-based social engineering. Mapped the activity to MITRE ATT&CK techniques including T1566 Phishing, T1566.002 Spearphishing Link, and T1204 User Execution, then prepared a SOC-style incident report with severity, impact, evidence, final verdict, containment actions, and remediation recommendations.

📖
SIEM & Security Monitoring

Multi-Domain SOC Monitoring using Splunk SIEM

Built a SOC lab using Splunk, Ubuntu, Kali Linux, and VirtualBox to monitor security events. Configured log ingestion for Linux authentication and firewall logs, simulated SSH brute-force attempts and network scanning, created SPL detection queries, alerts, and dashboard visualizations for security monitoring and incident analysis.
