When is the security for the Historian Server established?

The security for the Historian Server is established at the time of installation because this is when the foundational settings and configurations related to security protocols are applied. During installation, the server is set up with default security measures, user authentication methods, and access control lists that determine how data can be accessed and modified. This initial setup is crucial to ensure the server is protected from unauthorized access right from the start.

While user role modifications, first user logins, and regular system checks are important aspects of ongoing security management, they do not establish the core security framework. Instead, they serve to modify, verify, or enhance the security measures that were initially implemented during installation. The installation phase is key because it allows administrators to define baseline security parameters that govern user interactions with the server from the outset.
