Key Responsibilities
Design, architect, and document robust network solutions for SCADA and OT environments.
Develop detailed network topology diagrams, configuration templates, and technical documentation.
Configure and validate routing protocols, static routing, and NAT for secure multi-site communication.
Implement and troubleshoot MPLS and IPsec VPN tunnels, including 4G failover for resilient remote connectivity.
Deploy secure VLAN segmentation strategies (e.g., OT/ICS, Management, and SCADA zones).
Integrate Azure AD authentication for SCADA IPC environments where applicable.
Ensure compliance with relevant cybersecurity and regulatory frameworks, including:
NIS Directive for critical infrastructure protection
IEC 62443 cybersecurity standards for industrial control systems
Water OTASP standards (Asset Monitoring, Telemetry, Automation, SCADA software design)
Implement OT security best practices, including SIEM logging, vulnerability scanning (e.g., Qualys), and endpoint protection (e.g., Microsoft Defender).
Provide advanced troubleshooting and root cause analysis across geographically distributed sites.
Manage firewall rules and secure remote access solutions in industrial environments.
