I am a cybersecurity professional building hands-on experience in security operations, threat detection, incident investigation, network security, and defensive security.

My portfolio documents practical cybersecurity labs where I analyze security alerts, investigate network and endpoint activity, correlate evidence, map observed behavior to MITRE ATT&CK, and recommend appropriate security controls.

• SOC alert triage and incident investigation
• SIEM monitoring and analysis with Wazuh
• Network traffic analysis with Wireshark
• Linux security and log analysis
• pfSense firewall configuration and network security
• MITRE ATT&CK mapping and threat analysis

Wazuh Wireshark Kali Linux Ubuntu Linux pfSense Cisco Packet Tracer VirtualBox Linux SSH MITRE ATT&CK

Conducted a simulated SOC investigation involving SSH brute-force activity, successful authentication, and subsequent privileged activity. Correlated Wazuh alerts with native Linux logs and mapped observed security events to MITRE ATT&CK.

Skills: SOC Investigation · Wazuh SIEM · Alert Triage · Linux Log Analysis · Event Correlation · MITRE ATT&CK

Built an isolated network-security lab using Kali Linux, Ubuntu, pfSense, and Wireshark to analyze network traffic, investigate anomalies, and implement firewall controls.

Skills: Network Security · pfSense · Wireshark · Traffic Analysis · Firewall Configuration

Designed and tested a segmented enterprise network using Cisco Packet Tracer, including static IPv4 addressing, inter-network routing, ACL implementation, and connectivity testing.

Skills: Network Design · Cisco Packet Tracer · IPv4 · Routing · ACLs · Network Segmentation

Captured, filtered, and analyzed network traffic using Wireshark and Kali Linux, including ICMP and DNS traffic.

Skills: Wireshark · Packet Analysis · ICMP · DNS · Network Traffic Analysis

Hands-on Linux command-line practice covering foundational Linux skills relevant to cybersecurity and system administration.

Skills: Linux · Command Line · File System Navigation · System Administration

I am developing deeper practical expertise in SOC operations, security monitoring, incident investigation, threat detection, and defensive security.

My goal is to continue building evidence-based cybersecurity projects that demonstrate how I investigate security events, interpret technical evidence, and translate findings into practical security recommendations.
