OPC UA Interface Data Source
The system:inmation OPC UA client and server support different communication security policies, user token policies, and application authentication methods as specified in the OPC UA standard. The supported security policies are:
Sign and Encrypt
These come with different supported key lengths and cryptographic algorithms. A security policy different from None ensures data integrity and privacy based on strong cryptographic algorithms.
Configurable user token policies are:
The User Name policy in the system:inmation UA server is used to authorize UA clients against the Core security model.
As in the OPC Classic case, communication between the system:inmation Core service and the Server service components is authorized using a passphrase and client credentials. An authentication and transport encryption configuration between the two service components is currently unavailable.
