How to implement periodically called Drupal 8 module?

Question

Drupal

Some module functions must be executed at a certain time (once a day).
It is planned to use the Linux system service - Cron to periodically run functions.
As an option, call the page of the module, the controller of which will execute the code.
But here the question arises: how to restrict access to this page?
How do I make it clear to the called (Cron task) page that it is being accessed by an authorized user?
Is the approach described above correct or does the solution look different?
