Secure Remote Access for Cyber Physical Environments

This solution brief outlines the Secure Remote Access (SRA) framework developed by Armis, designed specifically for cyber physical environments. The document details the limitations of traditional IT-centric remote access solutions, highlighting the vulnerabilities associated with all-or-nothing access models and cumbersome firewall rules. It emphasizes the necessity of adopting a zero trust approach to enhance security and operational integrity in operational technology (OT) environments. The SRA framework enables granular, identity-driven access control, allowing organizations to manage access effectively while minimizing risks associated with unauthorized access. Key features include continuous verification, least privilege access, and the ability to unify access control across various cloud services. The brief also discusses compliance with industry standards such as NERC-CIP and IEC 62443, ensuring that organizations can meet regulatory requirements while maintaining robust security measures. Overall, the SRA framework aims to provide a comprehensive solution for securing remote access in complex industrial settings.
