    Graduate Research Assistant

    Sam Houston State University·Huntsville, TX

    Phase 2:

    • Engineering GuardedEdge, an IoT edge security platform by integrating AWS IoT Greengrass v2, Device Defender along with Device Management for threat detection and response.
    • Reduce baseline poisoning risk by designing a guarded adaptation workflow that promoted new behavioral baselines only after attack and false positive checks.
    • Building a reversible incident response ladder by implementing logging, rate limiting, topic restriction, rollback, restart, and isolation actions for affected devices.
    • Improve endpoint security and local remediation by deploying AWS IoT Greengrass v2 components for throttling, restart, topic restriction, and containment.
    • Developing auditable fleet response workflows by using device grouping, fleet indexing.
    • Strengthen IoT threat detection by using AWS IoT Device Defender ML Detect, Rules Detect along with Audit to identify anomalies and configuration drift.

    Phase 1:

    • Conducted research on IoT honeypot architectures to detect and analyze advanced persistent threats in smart home and industrial control system environments.
    • Monitored and categorized 100+ attack vectors, documenting entry points, exploitation methods, and attacker behavior.
    • Executed 10+ simulated attack scenarios and 3+ tabletop exercises to validate detection capabilities.
    • Deployed adaptive container imaging, achieving less than 10 minute deployment time for new honeypot instances.
    • Collaborated on federally funded cybersecurity research focused on intrusion detection in critical infrastructure networks.
    • Generated threat intelligence reports documenting 50+ unique IoT attack patterns for threat hunting operations.
    • Presented research findings and contributed to peer-reviewed publications in cybersecurity and digital forensics.
