Real-time maritime weather conditions including wind speed, wave height, barometric pressure and sea state — updated for the vessel's current position.
📡 Visitor Intel
Visitor intelligence panel — displays connection origin, language, timezone and maritime region context for site visitors.
🛰 Vessel & Fleet Analysis
Live AIS vessel tracking map — displays real-time positions of commercial vessels including cargo ships, tankers and bulk carriers operating in Korean and East Asian waters.
Chapters 1 through 6 established the full spectrum of technical design and security documentation. Chapter 7 addresses the final validation question: Do the security functions described in the documentation actually work? This chapter explains the verification layer between design and certification — security testing as attack-scenario-based control validation.
Chapter 7
Security Testing Fundamentals — Verifying That Security Actually Works
1️⃣ Why Does Chapter 7 Appear After Documentation?
Up to Chapter 6, all content covered design and documentation. Chapter 7 marks the final step before certification readiness.
Ch.1 OT Systems→Ch.2 Network→Ch.3 Host→Ch.4 Attacks→Ch.5 Monitoring→Ch.6 Documentation→Ch.7 Testing ✦
The critical question in certification:
"Do the security functions described in the documentation actually work?"
→Chapter 7 explains the verification layer between design and certification — where documented security claims become proven security controls.
2️⃣ Overall Structure of Chapter 7
Security testing is not just functional testing — it is about validating the effectiveness of security controls under attack conditions.

Expected Behavior Verification
Testing is not about checking functionality — it is about verifying how the system behaves under attack conditions.
3️⃣ Structure of Key Test Domains
UR E26-based security testing consists of the following domains, each aligned with real attack stages:
3 Verify system detects or rejects unauthorized changes
9️⃣ Audit & Logging Testing
Security events must always be recorded.
Without logs: attacks cannot be detected and incident analysis becomes impossible.
What Logging Testing Verifies
· Recording of login events· Recording of privilege changes· Recording of system modifications
Example Test Scenarios
· Login failure events· Configuration changes· User creation actions
The system must confirm that these events are properly logged.
🔟 Test Execution Environment
Security testing is difficult to perform in live operational environments. Therefore, a dedicated Test Environment is used — one that mirrors the real system without impacting actual operations.
🖥 Test PLC
Identical firmware & configuration to production
🔌 Simulated Network
Isolated topology matching production
💻 Test Workstation
EWS/HMI environment for test execution
1️⃣1️⃣ Mapping Security Testing to Attack Models
The attack stages from Chapter 4 map directly to the test domains in Chapter 7 — demonstrating that security testing is fundamentally attack scenario-based validation.
Attack Stage
Corresponding Test
Initial Access
Authentication
Execution
Malicious Code Protection
Privilege Escalation
Authorization
Credential Access
Authentication / Logging
Lateral Movement
Communication Security
Impact
System Integrity
✅ Key Takeaway
Security testing in OT is not about verifying features — it is about validating how systems behave under attack conditions.
