Projects & Case Studies

Hands-on cybersecurity work with measurable outcomes

A collection of cybersecurity projects highlighting security analysis, incident response, reporting, and defensive operations work through concise case-study format.

Case Studies

04

Frameworks Applied

NIST / MITRE

Primary Focus

Detection + IR

Evidence Included

Dashboards / Logs

Project 01

Security Operations Dashboard (Simulated)

Built a post-implementation dashboard summarizing login attempts, IDS/IPS alert counts, severity distribution, and response timing metrics for a cloud-based environment.

What I Did

  • Defined security KPIs for detection and response performance
  • Visualized trends before/after MFA adoption
  • Summarized alert severity distribution and integrated log sources

Tools / Concepts

  • Data visualization
  • SIEM-aligned reporting
  • Identity control hardening
  • Security metrics communication
SIEM MFA Monitoring Security Metrics

Project 02

Incident Response Workflow Mapping (NIST-Aligned)

Designed an incident response workflow mapping detection through post-incident review, aligned to NIST SP 800-61 concepts and operational security team responsibilities.

What I Did

  • Mapped response stages from alert intake to lessons learned
  • Documented analyst actions and decision points
  • Created a reusable communication-friendly process diagram

Tools / Concepts

  • NIST incident response lifecycle
  • Runbook design
  • Containment and recovery planning
  • Continuous improvement controls

Project 03

Threat Detection & Triage Lab

Built a threat detection and triage exercise focused on reviewing suspicious authentication activity, validating alerts, and documenting response recommendations.

Evidence Included

  • Query samples or detection logic
  • Alert timeline and severity reasoning
  • Containment recommendation

Outcome Focus

  • False-positive reduction
  • Improved triage time
  • Higher confidence classification

Project 04

Vulnerability Remediation Program Snapshot

Developed a remediation-focused workflow for prioritizing findings, validating fixes, and tracking issues through closure across systems and infrastructure.

Project Scope

  • Asset inventory and severity prioritization
  • Patch/mitigation coordination
  • Verification and residual risk notes

Tools

  • Nessus / Qualys (if used)
  • Ticketing workflow
  • Baseline hardening checklists
