How to secure the logs?

Buddy if the users share by orchestrator, you can set the users with specific restriction with this option .
your user at the right top corner → users → role → select the role of the users
can set the condition buddy

or if the machine itself is been shared, you can set the log folder path to any folder in your username in the drive that wont allow the other users to see the folders and to change the folder path of log kindly have a look at this buddy

Kindly try this and let know buddy
