Learning Objectives
- Understand industrial cybersecurity challenges
- Identify OT vs IT security differences
- Apply security frameworks and best practices
- Basic networking concepts
- Week 6: Cloud/IoT
1. Industrial Cybersecurity Challenges
- Legacy Systems: Old PLCs and RTUs designed without security (no authentication, no encryption)
- OT/IT Convergence: Previously isolated (air-gapped) systems now connected to internet and enterprise IT
- Real-Time Requirements: Security measures must not introduce latency that affects production
- Long Lifecycles: Industrial equipment lasts 10-20+ years, running outdated software
- Safety Implications: Cyber attacks can cause physical damage (Stuxnet destroyed centrifuges)
2. OT vs IT Security
| Aspect | IT Security | OT Security |
|---|---|---|
| Primary Goal | Confidentiality | Safety & Availability |
| Patching Cadence | Regular (monthly) | Rare (requires planned downtime) |
| Device Lifetime | 3-5 years | 10-20 years |
| Communication Protocols | TCP/IP, HTTP, HTTPS | Modbus, Profinet, OPC UA, EtherCAT |
| Risk Impact | Data breach | Physical damage, safety risk |
3. Security Framework: Defense in Depth
- Physical Security: Access controls, locks, cameras, biometrics
- Network Segmentation: DMZ between IT and OT, firewalls, VLANs
- Endpoint Protection: Antivirus for industrial PCs, application whitelisting
- Application Security: Secure coding practices, code review
- Data Security: Encryption at rest and in transit, backups
- Identity & Access: Role-based access, multi-factor authentication
- Monitoring: SIEM, intrusion detection, anomaly detection
Q1: Why is cybersecurity critical in Industry 4.0?Increased connectivity creates more attack surfaces. A cyber attack on industrial systems can cause physical damage, production loss, safety hazards, and environmental damage. Q2: What is the difference between IT and OT security priorities?IT prioritizes data confidentiality (protect data). OT prioritizes safety and availability (production must continue safely). Q3: What is defense in depth?Multiple overlapping security layers: if one layer fails, the next continues protection. Physical, network, endpoint, application, data, and monitoring layers. Q4: What was the Stuxnet attack?2010 cyber attack targeting Iranian nuclear centrifuges. Malware exploited Windows vulnerabilities to damage PLCs controlling centrifuges, demonstrating cyber-physical attack potential. Q5: What is network segmentation in OT?Dividing network into zones (corporate, control, safety) separated by firewalls. Prevents attacks from spreading from IT to OT systems.
