IEC 62443 Industrial Cybersecurity
Zone & conduit architecture, security levels, and certification for industrial automation and control systems.
Common IEC 62443 Challenges
Industrial cybersecurity comes with unique complexities that off-the-shelf IT security approaches don't solve.
IT/OT Convergence
Bridging the gap between IT security and operational technology — different priorities, different risks, one framework.
Security Level Selection
Determining the right security levels (SL-T) for zones and conduits based on realistic threat assessment.
Legacy System Integration
Securing brownfield installations with legacy PLCs, SCADA, and protocols that weren't designed for cybersecurity.
The Structured Approach
A proven four-phase process from initial risk assessment to ongoing security operations.
Security Assessment & Zone Model
High-level risk assessment, zone & conduit partitioning, security level target definition.
Security Requirements & Design
Derive security requirements per zone, select countermeasures, design secure architecture.
Implementation & Verification
Deploy security controls, configure monitoring, verify against security levels.
Operations & Continuous Improvement
Security monitoring, patch management, incident response, periodic reassessment.
Key Capabilities & Deliverables
Every engagement is structured to deliver tangible, audit-ready outputs.
Zone & Conduit Modeling
Visual zone architecture with data flow analysis and conduit security requirements.
Security Level Assessment
Systematic SL-T/SL-A/SL-C gap analysis per zone with remediation tracking.
Asset Inventory
Complete OT asset discovery and classification with vulnerability correlation.
Network Architecture
Segmentation design, firewall rule sets, DMZ architecture for IT/OT boundary.
Compliance Mapping
IEC 62443-3-3 and 4-2 requirement mapping with evidence management.
Risk Dashboard
Ongoing risk visualization with security level compliance tracking.
