How Cybersecure Are PLCs Directly Connected to the Cloud? (AWS)

July 27, 2024 / / 0 Comments

The integration of Programmable Logic Controllers (PLCs) with cloud platforms like Amazon Web Services (AWS) has become increasingly common. This integration promises enhanced data analysis, remote monitoring, and scalability but also brings a host of security considerations. So the question comes: how secure are we if we connect directly a PLC to the Public Cloud, such as Azure or especially AWS?

The Challenge of the Industrial Pyramid

To grasp the security considerations, it’s essential to understand the “industrial pyramid,” a hierarchical model that illustrates the structure of industrial automation systems. At its base are Field Devices, such as sensors and actuators. Above these are PLCs, which manage and control industrial processes. Next, in the Supervisory Control and Data Acquisition (SCADA) layer, systems aggregate data from multiple PLCs. The top layers include Manufacturing Execution Systems (MES) and Enterprise Resource Planning (ERP) systems, which manage and optimize production processes and business operations.

When connecting PLCs directly to the cloud, bypassing the traditional layers of the industrial pyramid, we expose the network to potential vulnerabilities. In a typical industrial setup, data flows from PLCs to SCADA systems and then to higher-level MES and ERP systems, providing multiple layers of security and control. However, by establishing a direct link between PLCs and AWS, we effectively reduce these intermediary safeguards, which could compromise network security if not managed properly. This direct connection can be particularly risky in complex or large-scale operations with multiple interdependent systems. However, for a very simple factory with minimal complexity and fewer interconnections, the direct link might be manageable with appropriate security measures, such as robust encryption and strict access controls, ensuring that the risks are kept within acceptable limits.

Security Challenges and Considerations

When connecting PLCs to AWS, several security challenges arise, primarily revolving around the protocols used for communication. PLCs commonly use industrial protocols like Modbus, OPC, and Profinet, each with varying levels of inherent security.

1. Protocol Security: Many traditional industrial protocols were not designed with security in mind. For instance, Modbus lacks built-in encryption and authentication, making it vulnerable to interception and unauthorized access. OPC, while more versatile, also often requires additional layers of security to ensure safe data transfer. Profinet offers improved security features but still requires careful configuration to mitigate risks. Want to know how to integrate OPC UA with AWS?

2. Network and Data Security: To address these challenges, securing network communications is essential. Implementing VPNs, firewalls, and encryption can protect data in transit between PLCs and AWS. AWS provides robust network security features such as Virtual Private Cloud (VPC) and AWS Shield, which help protect against external threats. For data at rest, AWS employs encryption standards like AES-256, ensuring that sensitive information is safeguarded.

3. Access Management: Effective access management is critical for maintaining security. AWS Identity and Access Management (IAM) enables fine-grained control over who can access and manage AWS resources. For PLCs, using secure gateways or edge devices that enforce authentication and encryption is crucial for safeguarding data exchanges.

4. Compliance and Monitoring: Ensuring compliance with industry regulations and standards is important for security. AWS offers tools like AWS CloudTrail and Amazon CloudWatch for monitoring and logging activities, which help in detecting and responding to potential security incidents.

Best Practices for Securing PLCs on AWS

  • Use Encrypted Communication: Ensure that all data transmitted between PLCs and AWS is encrypted. This is how you set up a MQTT connection from TIA Portal.
  • Implement Strong Access Controls: Configure AWS IAM roles and policies appropriately, and secure edge devices with strong authentication.
  • Monitor and Log Activities: Utilize AWS CloudTrail and Amazon CloudWatch to monitor activities and detect anomalies.
  • Regular Updates and Patches: Keep firmware and software up to date to protect against known vulnerabilities.
  • Adhere to Compliance Standards: Ensure that your implementation meets industry-specific regulatory requirements.
