Ensure 'Allow read access via the File System API on these sites' is set to 'Disabled'

보통레벨 2자동edge

설명

This policy setting allows organizations to list the URL patterns that specify which sites can ask users to grant them read access to files or directories in the host operating system´s file system via the File System API. The recommended state for this setting is: Disabled. Rationale: This API allows web apps to read from files and folders on user devices. It also allows for the reading files and the File System Access API provides the ability to open a directory and enumerate its contents. The policy is Disabled when it is not present: the audit prints 'absent' when neither the value FileSystemReadAskForUrls nor a populated list subkey FileSystemReadAskForUrls exists under HKLM\SOFTWARE\Policies\Microsoft\Edge, otherwise the configured entries.
