Zero-Trust Access for Industrial Systems (Ot Cybersecurity)
Project Scope
Design and implement a Zero-Trust security framework for industrial systems that enforces strict identity verification, role-based access control, and network segmentation across OT environments.
Business Challenges
- Legacy OT systems with weak authentication mechanisms
- Flat network architectures increasing lateral movement risk
- Unsecured remote access to PLCs and control systems
- Limited visibility into user activities within OT networks
- Difficulty aligning IT security policies with OT operational constraints
ARi’s Solutions
- Implement identity-based access control with multi-factor authentication (MFA)
- Enforce least-privilege access policies for users and devices
- Apply network segmentation and zone-based architecture (IEC 62443 aligned)
- Monitor and log all access events with anomaly detection
- Secure remote maintenance through encrypted VPN and session control
ARi’s Value Proposition
- Reduced risk of unauthorized access and cyber intrusions
- Containment of threats through micro-segmentation
- Improved visibility and audit readiness
- Stronger protection for critical industrial assets
- Enhanced trust and resilience across OT environments
