Join Don Pearson and Travis Cox from Inductive Automation and Chris Harlow from Bedrock Automation as they discuss an end-to-end approach to SCADA/ICS security that encompasses software as well as hardware. You’ll learn about: What built-in security is and why it’s essential Security benefits of OPC UA and MQTT How to secure your PLC, RTU, or DCS Best practices such as role-based access and authentication Security risks that are often overlooked And more!

8. Cyber Threats to ICS and SCADA
• Stolen Credentials
• Ransomware
• Human Factors
• Social Engineering
• Root Kit Attacks
• Session Hijacking
• Counterfeiting
• DDoS Sensors/Actuators
Networks
Controllers
Client
Management
Computers

9. Attack Vectors
• Database attacks
• Escalated privilege exploits
• Network components/
communications hijacking
• ‘Man-in-the-middle’ attacks
• Backdoors and holes in network
perimeter (field devices)
• Attacks that access thru pins
Outcomes
• Denial of Service (DoS): crash the
SCADA server leading to shutdown
condition
• Delete SCADA server system files:
system downtime and loss of
operations
• Plant a Trojan and take complete
control of system
• Log sensitive company operational
data for criminal or competitive use
Attack Vectors and Outcomes

10. What You Want in a “Secure” System

11. The Flaw in Typical SCADA Architectures

14. What if Security Could Be...
Built In versus Bolted On

15. Then Security Would Be...
Layered and Embedded

16. And The Result Is...
Security that just happens!
To the Hardware Root of Trust
✓ Authenticated Control, I/O, IIoT Edge
✓ Authenticated Firmware
✓ Authenticated Control Database
✓ Authenticated Applications
✓ Authenticated Workstations
✓ Authenticated Networks
✓ Role-Based Access Authenticated
✓ Biometric Authentication

17. SCADA Security - Device/PLC Connections

18. SCADA Security - Device/PLC Connections
Secure Your Device/PLC Connections:
• Native device communication options:
- Keep on a separate, private OT network
- Network segmentation
- VLAN with encryption
- Set up routing rules
- Use an edge gateway as a bridge between device & network
• OPC UA and MQTT communication offers built-in security, and
communications can be encrypted over TLS

19. SCADA Security - Device/PLC Connections

20. SCADA Security - Rethink Your Idea of Security
• Understand that no system is inherently secure or insecure
• You cannot eliminate security risk but you can significantly mitigate it
• Focus on preventing intrusion
• Don’t only secure the ICS/SCADA platform itself – you also need to
secure all of the connections from the SCADA to devices,
databases, clients, etc.

21. SCADA Security - Physical Security
Implement physical security measures:
• Badges & badge readers
• Physical media controls (laptops, phones, USB keys, etc.)
• Video monitoring
• Policies and training
• Guards

22. SCADA Security - Operating System
Protect your OS by:
• Removing any unnecessary programs.
• Keeping OS patches & service packs up-to-date.
• Disabling remote services on Windows.
• Setting up firewalls to restrict network traffic; close all ports and
only reopen necessary ports.
• Setting up firewalls on redundant servers.
• Getting a VPN device with good multi-factor authentication if remote
access is required.

23. SCADA Security - Databases

24. SCADA Security - Databases
Protect the database connection with the SCADA software:
• Use TLS encryption if your database supports it.
• Create a separate user account with limited privileges, instead of using a
database owner account such as root or sa.

25. SCADA Security - Encryption
Use encryption to:
• Protect all data sent over HTTP
• Protect against snooping & session hijacking
• Protect the SCADA gateway
• Encrypt OPC UA communication
• Help secure databases that support TLS/SSL
• Secure native device communication by using with a VLAN

26. SCADA Security - Databases

27. SCADA Security - Server & Clients

28. SCADA Security - Authentication
Use authentication for:
• Username/password (No default passwords or sticky notes)
• User- and role-based security (Principle of Least Privilege)
• Biometrics (fingerprints, retina scans)
• Public Key Infrastructure (PKI)
• Key cards
• USB tokens
• Application security (role-based application settings/permissions)
• Database connection encryption
• OPC UA connections

29. SCADA Security - Roles
Security roles:
• Security is based on roles assigned to specific users
• You can create structure or hierarchy for roles (not default)
• Users can have access to many roles or none
• Be sure to think about how different roles affect the security of the project

30. SCADA Security - Zones
Security zones:
• Lists of gateways, computers, or IP addresses that are defined and
grouped together
• Place additional policies and restrictions on defined zones
• Provide read-only and read/write access to specified locations
• Help keep different areas of the business separate while
allowing them to interconnect

31. SCADA Security - Audits
Auditing:
• Record details about specific events
• Track down who did what from where
• Helpful in deterring attacks by SCADA insiders
• Use audit logs, trails, profiles

32. SCADA Security - Secure Standard Architecture

33. SCADA Security - Secure Hub & Spoke Architecture

34. Public-Private Key Infrastructure

35. How to Manage Keys
• A Cloud SaaS is deployed for managing and administering cyber keys and certificates
• User security administrator tool to define role-based access control
• Keys embedded in the controller, no need for persistent cloud connection

36. Securing ICS – Best Practices
Use a secure CPU with a
secure RTOS
Use physically secure controllers
Use encryption between ICS
and SCADA
Use a PKI for role based access
Sign and Encrypt ICS
application code
Use mutual authentication
between ICS and SCADA
Use ICS hardware with built in
Anomaly Detection
Ask your vendors what they’re doing
to secure their products

37. Securing SCADA – Best Practices
Secure PLC and device connections
Implement physical security measures
Protect the operating system
Use encryption
Use authentication
Protect the database connection
Use role-based security
Use security zones

38. Closing Discussion Question
To wrap up the discussion, what are your thoughts about how Inductive
Automation and Bedrock Automation can help industrial organizations
improve their security, both now and in the future?
