Ensure File Key Management Encryption Plugin files have appropriate permissions
Description
Certain Key Management Encryption plugins must store sensitive information in files for later retrieval. Such files should have proper permissions. Reads file_key_management_filename/filekey from the server option groups; fails when the plugin is not configured or a key file is not mysql:mysql with mode 750 or stricter.

compliant
Méthode de correction
Méthode de correction: Recommandation ou correctif d'infrastructure
chmod 750 <file> (or stricter, e.g. 640/600) && chown mysql:mysql <file> for file_key_management_filename and a FILE: file_key_management_filekey; if the plugin is not configured, implement data-at-rest encryption first (4.9).
