The initial security configuration of Windows objects is performed
automatically by Plesk during installation. Plesk creates a number of
default accounts and sets user permissions on all Windows objects found
on the freshly installed Plesk-managed server. All pre-existing security
settings are erased and new security settings are applied according to
the security rules found in the default disk security metadata
file.
Subsequently, each time a new hosting account is created, the created
default hosted objects are assigned user account permissions based on
the security rules found in the corresponding hosting security metadata
file instantiated from a current hosting security
metadata file template.
If a folder or a file is created, for which no security rule is set in
the security metadata, the object will automatically inherit security
settings of their respective parent containers.
