What options are available under Security in the AVEVA Historian Configurator?

The available options under Security in the AVEVA Historian Configurator include the ability to create user accounts and delete existing user accounts. This functionality is crucial for managing access to the Historian Server, as it allows administrators to both grant new users access to the system and remove access for users who no longer require it.

Creating a user account ensures that new personnel can effectively utilize the system while maintaining operational integrity and security. Deleting user accounts, on the other hand, helps in keeping the system secure by ensuring that former employees or irrelevant accounts do not allow unauthorized access. The ability to manage user accounts in this manner ensures that the system remains secure and compliant with organizational policies regarding data access.

The other options focus on limited functionalities that do not encapsulate the full range of user management capabilities. For instance, being able to only add existing user accounts or just delete them does not provide the comprehensive control required for effective security management in the context of the AVEVA Historian. Similarly, modifying user account privileges without the ability to create or delete accounts would not adequately support a robust security policy, as it lacks the essential functions of user account lifecycle management.
