ISA/IEC 62443-3-3 Overview

Industrial Automation and Control Systems (IACS) face a complex threat landscape across geographically dispersed sites, legacy assets, and specialized operational technology (OT). While the ISA/IEC 62443-3-3 standard provides the global benchmark for securing industrial environments, mapping its 7 Foundational Requirements (FRs) to your existing security architecture can feel overwhelming.

You don't need to rebuild your security program from scratch—you need a proven way to operationalize compliance.

This White Paper Details How to:

• Map out technical fulfillment for Foundational Requirement 1 (FR1: Identification & Authentication Control) through local, LDAP over SSL, or SAML integrations enforcing Multi-Factor Authentication (MFA) and strict Role-Based Access Control (RBAC).

• Learn how Claroty xDome Secure Access enforces Foundational Requirement 2 (FR2: Use Control) via dual approval workflows for critical OT asset state changes, idle session locking, and remote session termination.

• Detail centralized, time-correlated audit logging capabilities exportable to SIEM/SOAR platforms via Syslog, satisfying non-repudiation and immutable audit trail requirements.
