Introduction

This section provides a security model for the OPC unified architecture specified in GB/T 33863. This standard is given for the development of standard interfaces

The process of analysis and design, the standard interface can be accelerated by a number of suppliers to complete the application development, and to achieve the internal operation of the seamless

connection.

OPC unified architecture - Part 2. Security model

1 Scope

This part of GB/T 33863 gives an OPC Unified Architecture (UA) safety model that describes what OPCUA expects to run

Security threats in hardware, software and software environments, and how OPCUA uses other standards for security. This section is given in the OPC

Overview of the safety features specified in the UA specification. This section refers to services that are normative in other parts of this standard

Shooting and regulation.

Note. Many other aspects of security are addressed when developing applications. Since OPCUA specifies a communication protocol, this section focuses on protection

The security of data exchange between.

This does not mean that application developers can ignore other aspects of security, such as the protection of permanent data from tampering. The developer should observe

All secure content and determine how to handle in the application.

This section is used to guide the development of OPCUA client or server applications or to implement the OPCUA service layer.

This section assumes that the reader is familiar with Web services and XML/SOAP. For information on these technologies, refer to SOAP Part 1 and

Part 2.
