A computer implemented method for security hardening of a renewable energy device system including: i) determining a target security standard for the system using a first model trained using a first machine learning process that predicts the target security standard from a security posture of the system. The method also includes ii) identifying one or more deviations in the security posture of the system from the target security standard, and iii) using a second model trained using a second machine learning process to recommend an action to perform on the system to move the security posture of the system toward the determined target security standard.

Security hardening of a renewable energy device system

Techniques for authenticating and authorizing user access to a component of a power plant within a private network of a renewable power plant having wind turbine generators. One technique includes providing at a local computer system in the private network a list of credentials and authorizations representing a plurality of identifiers and authenticators of users and corresponding access authorizations. The local computer is in direct communication with components of the power plant and is configured to receive a request for access from a user via a computer interface in the component in the private network. If the requested access can be granted by consulting the list of credentials and authorizations, the grant is communicated from the local computer to the computer interface in the component, and in case access cannot be granted, a request for update of the list of credentials and authorizations is communicated from the local computer system to a central computer system outside the private network.
