1. Risk Assessment & Gap Analysis

• Comprehensive evaluation of existing OT networks, control systems, and connected assets.
• Identification of vulnerabilities in PLCs, HMIs, engineering workstations, and field devices.
• Alignment with ISA/IEC 62443, NIST, and Saudi NCA frameworks.

2. Network Architecture & Segmentation

• Secure zone and conduit design between control, DMZ, and enterprise layers.
• Implementation of defense-in-depth strategies to isolate critical assets.
• Deployment of firewalls, data diodes, and secure gateways for OT/IT convergence.

3. Endpoint & Controller Hardening

• Secure configuration of PLCs, DCS nodes, and HMI/SCADA servers.
• Firmware and patch management programs for industrial devices.
• Whitelisting and access control policies to prevent unauthorized code changes.

4. Real-Time Monitoring & Incident Response

• Continuous monitoring using ICS-aware intrusion detection systems (IDS).
• Integration with Security Operations Centers (SOC) for 24/7 visibility.
• Incident response playbooks tailored to process-critical environments.

5. Secure Remote Access & Maintenance

• Multi-factor authentication for remote vendors and service teams.
• Encrypted VPN and jump-host configurations for maintenance connections.
• Detailed audit trails of user and system activities.
