Suggestions for Enhancing OPC UA Security Features|Suggestions|Forum|OPC Foundation

Hello,

I’ve been working with OPC UA for a while now and have had a positive experience with its flexibility and broad support across different industries. However, I’d like to suggest a few enhancements to the security features that could help increase confidence and ease of use for developers and end-users alike.

Firstly, while OPC UA offers encryption and authentication, I feel that integrating more modern and customizable multi-factor authentication options could make a significant difference, especially in environments with high-security demands. Having support for biometric or hardware-based authentication methods as part of the standard would make the system more robust.

Additionally, I think the management of user roles and permissions could be made more flexible. It would be helpful to have finer control over what specific data points a user can access, along with auditing capabilities that provide clear logs of who sap sacaccessed what and when. A more granular control mechanism would be useful in critical industrial and financial applications where data sensitivity is paramount.

Lastly, I would like to see more comprehensive documentation and best practices around security configurations. Though the available resources are helpful, a clear, step-by-step guide on how to implement the highest security standards with OPC UA could save time and prevent common mistakes, especially for those new to the protocol.

Thank you for considering these suggestions. I look forward to hearing your thoughts on these ideas.
