> SIEM Implementation and Optimization
Implemented and optimized a Splunk SIEM solution for a medium-sized enterprise, improving threat detection capabilities and reducing false positives.
Project Goals:
- Centralize security logs from diverse systems
- Create custom dashboards for security operations
- Develop correlation rules for advanced threat detection
- Automate routine analysis tasks
Technologies Used:
Key Outcomes:
- Reduced alert investigation time by 45%
- Decreased false positive rate by 60%
- Created 15+ custom dashboards for different security scenarios
- Implemented automated threat intelligence integration
> Threat Hunting Framework Development
Developed and implemented a systematic threat hunting methodology to proactively identify adversaries in the network before they trigger alerts.
Project Goals:
- Create a repeatable process for threat hunting operations
- Develop hypotheses based on TTPs from MITRE ATT&CK framework
- Build custom detection scripts for hunting specific behaviors
- Document findings and convert successful hunts into permanent detections
Technologies Used:
Key Outcomes:
- Discovered 3 previously undetected persistence mechanisms
- Identified lateral movement techniques evading traditional detection
- Created 20+ hunting playbooks for different adversary techniques
- Developed 12 new detection rules from hunting findings
> Security Automation
Developed a semi-automated system for analyzing reported phishing emails, extracting IOCs, and streamlining the triage process.
Project Goals:
- Reduce manual effort in analyzing reported phishing emails
- Extract and analyze indicators of compromise (IOCs)
- Automate reputation checks against threat intelligence sources
- Generate standardized reports for incident tracking
Technologies Used:
Key Outcomes:
- Reduced phishing analysis time by 70%
- Improved accuracy of IOC extraction
- Automated sharing of verified IOCs with security tools
- Created a historical database of phishing campaigns for trend analysis
> Incident Response Playbook Development
Created comprehensive incident response playbooks for the SOC team, standardizing the approach to common security incidents.
Project Goals:
- Standardize response procedures for common incident types
- Reduce mean time to respond (MTTR) for security incidents
- Ensure consistent evidence collection and documentation
- Facilitate knowledge transfer within the security team
Technologies Used:
Key Outcomes:
- Developed 15 detailed response playbooks for different incident types
- Reduced incident response time by 35%
- Improved consistency in evidence collection and documentation
- Created automated workflows for common response actions
