What security structure does the Historian use for user authentication?

The Historian utilizes Windows operating and SQL Server authentication for user authentication, which means it integrates with existing security frameworks provided by the Windows operating system and SQL Server. This approach leverages the built-in user management and security features of Windows, allowing organizations to manage user credentials, permissions, and roles through familiar environments.

Furthermore, by using Windows authentication, user credentials are not stored within the application itself; instead, they rely on the secure authentication mechanisms of Windows, including support for Active Directory. This provides a higher level of security due to centralized user management and the use of secure protocols for verifying user identities.

In addition, SQL Server authentication can complement Windows authentication by allowing users to log in directly with a username and password stored within the SQL Server instance, which can be useful in scenarios where applications need to access the database independently of Windows user accounts. Therefore, this dual structure covers various deployment needs and provides robust security.

Other options, such as firewall protection or solely relying on encrypted passwords, do not directly pertain to the user authentication process within the Historian. Firewalls protect network boundaries, and while encrypted passwords enhance security, they do not constitute an authentication structure. The OAuth system is also not utilized in this context, as it typically pertains to token
