Incident Handling & Network Threat Detection Using SIEM
Security Operations & Threat Investigation
SIEM Monitoring | Threat Detection | Incident Response | Network Analysis
This project focused on investigating cybersecurity incidents through security monitoring, network traffic analysis, threat detection, and incident response methodologies. Multiple security scenarios were analyzed using SIEM platforms, packet analysis tools, threat intelligence resources, and intrusion detection systems.
The project demonstrates practical application of incident investigation techniques, event correlation, malware analysis, phishing detection, packet inspection, and security monitoring aligned with industry cybersecurity practices.
Project Objective
The objective was to simulate and investigate real-world cybersecurity incidents, strengthen threat detection capabilities, analyze suspicious activities, and improve incident response skills using industry-standard security tools and methodologies.
Tools & Technologies
- Chronicle SIEM
- Splunk
- Wireshark
- VirusTotal
- Suricata IDS
- NIST Incident Response Framework
Figure: Incident Handling & Threat Investigation Journal
The investigation journal documents incident response activities, tools used, threat analysis procedures, affected assets, response actions, and security outcomes across multiple security events.
Security Investigations Performed
- Phishing email investigation using Chronicle SIEM.
- Malware analysis through VirusTotal and Splunk.
- Network packet capture and traffic investigation using Wireshark.
- Custom intrusion detection rule development using Suricata.
Key Findings
- Phishing emails can bypass security controls when users interact with malicious content.
- Threat intelligence platforms improve malware verification and incident validation.
- Packet analysis provides visibility into suspicious network communications and data exfiltration attempts.
- Custom detection rules strengthen monitoring capabilities and improve threat detection accuracy.
- SIEM platforms help centralize investigations through event correlation and log analysis.
Lessons Learned
- Incident response extends beyond detection and requires containment, eradication, and recovery actions.
- Network traffic analysis becomes more effective with protocol knowledge and filtering techniques.
- Threat detection improves when multiple security tools are used together.
- Continuous monitoring and investigation strengthen organizational security posture.
Project Impact
This project demonstrates practical application of cybersecurity operations, SIEM monitoring, threat detection, network traffic analysis, malware investigation, and incident response procedures.
The exercises enhanced analytical thinking, investigative techniques, security monitoring skills, and understanding of modern threat detection workflows used within security operations environments.
