Cybersecurity Analyst | Security Research Notes | SOC, SIEM, Incident Response, Vulnerability Management | ISC2 CC | 10+ Years IT Experience
I study, document, and build practical cybersecurity material around security operations, threat analysis, incident response, vulnerability management, access control, network security, and certification learning paths.
My background is rooted in hands-on IT operations. Across system administration, network management, and technical support, I have worked with Windows and Linux systems, user access, permissions, security policies, system logs, troubleshooting, and operational support. I use that experience to approach cybersecurity from a practical point of view: what happened, what evidence supports it, what risk it creates, and what action should be taken.
| Study Guide | Focus |
|---|---|
| Cybersecurity Study Guides Hub | Central index for all cybersecurity certification study notes |
| CompTIA Security+ SY0-701 Study Guide | Security+ exam objectives, security operations, IAM, GRC, risk, threats, vulnerabilities, and incident response |
| Google Cybersecurity Certificate Study Guide | Module-wise notes for foundations, risk, networks, Linux, SQL, assets, detection, Python, and security readiness |
| ISC2 Certified in Cybersecurity CC Study Guide | Domain-wise CC notes for security principles, BC/DR/IR, access controls, network security, and security operations |
| Work Area | Evidence |
|---|---|
| Cybersecurity Portfolio | SOC labs, detections, reports, scripts, sample logs, and screenshots |
| Windows Event Log Analysis | Authentication event review, Event ID 4624/4625 timeline, investigation notes |
| Windows Failed Logon Detection | SPL, KQL, Sigma-style detection logic, MITRE mapping, false-positive review |
| Python Log Triage Tool | Python automation for repeatable authentication-event triage |
| Security Policy and Risk Register | GRC documentation, risk register, control mapping, and policy writing |
I track current cybersecurity incidents and translate them into practical notes for detection, response, and security operations learning.
Topics I focus on:
- Threat intelligence and incident breakdowns
- SOC alert triage and investigation workflows
- Windows Event Log analysis and authentication activity
- SIEM detection logic using SPL, KQL, and Sigma-style structure
- Vulnerability management, risk rating, and remediation planning
- Access control, MFA, least privilege, and privileged access review
- Network security, DNS, HTTPS/TLS, Zeek-style traffic review, and repeated outbound connection analysis
- Security governance, policy writing, and risk communication
