Gives the OPC Unified Architecture (OPC UA) security model. This provides the security threats of the physical, hardware and software environments in which OPC UA is expected to run. Also provides how OPC UA relies upon other standards for security. Describes an overview of the security features that are specified in other parts of the OPC UA specification.

This part of IEC 62541 describes the OPC Unified Architecture (OPC UA) security model. It describes the security threats of the physical, hardware and software environments in which OPC UA is expected to run. It describes how OPC UA relies upon other standards for security. It gives an overview of the security features that are specified in other parts of the OPC UA specification. It references services, mappings, and profiles that are specified normatively in other parts of this series of standards.

Note that there are many different aspects of security that have to be addressed when developing applications. However since OPC UA specifies a communication protocol, the focus is on securing the data exchanged between applications.

This does not mean that an application developer can ignore the other aspects of security like protecting persistent data against tampering. It is important that the developer look into all aspects of security and decide how they can be addressed in the application.

This part of IEC 62541 is directed to readers who will develop OPC UA client or server applications or implement the OPC UA services layer.

It is assumed that the reader is familiar with Web Services and XML/SOAP. Information on these technologies can be found in SOAP Part 1 and SOAP Part 2.
