• Oversee operational security of IoT devices, smart building systems, and facility management platforms.

• Monitor vulnerabilities across OT and IoT ecosystems, including BMS, SCADA, and sensor networks.

• Implement network segmentation and zero‑trust principles across IT/OT convergence environments.

• Establish patch management, firmware updates, and lifecycle controls for connected devices.

E. Threat Monitoring & Vulnerability Management

• Establish continuous monitoring capabilities using SIEM/SOC tools.

• Lead vulnerability scanning, penetration testing coordination, and remediation tracking.
