For ringfencing policies to take effect, what must you ensure?

For ringfencing policies to take effect, it is essential that the application is shut down and restarted. This process allows the new policies to be applied effectively, as ringfencing is designed to create specific security boundaries around applications, controlling how they interact with the operating environment.

When an application is running, it may not register the new policy changes until it is restarted. This ensures that the application loads the latest configurations and adheres to the security boundaries outlined in the ringfencing policies. Simply updating the application or redeploying policies might not suffice if the application instance is still actively running and has already established its operational context. Additionally, notifying users of policy changes, while important for compliance and awareness, does not facilitate the operational application of the policies themselves.

Therefore, shutting down and restarting the application is a necessary step to fully implement the ringfencing policies and ensure that they are enforced correctly within the desired parameters of security and control.
