Where organisations use Operational Technology (OT), it's often their most critical infrastructure. This is especially true in Critical National Infrastructure (CNI), which relies heavily on OT and its secure operation.
The Importance of Securing Operational Technology
Operational technologies are computer-based systems that interact with the physical world, and are typically used to provide automation, remote visibility, and control of physical processes. OT environments present unique security challenges that require specific experience and skillsets to be addressed appropriately.
- OT and Cloud - The use of the cloud for OT applications is still in its infancy, and the reliance upon third-party hosting and network services to deliver critical OT services is a concern for most operators.
- Unique Regulations, Frameworks and Standards - Organizations with OT environments are typically subject to complex frameworks and regulations, such as ISA/ IEC 62443.
- Security Architecture - Poorly secured pathways in your security architecture can expose your critical systems to cyber threats. Simple controls assessments don’t always reveal open attack vectors and a more holistic analysis of the security architecture is required.
