In order to secure my server, I'd like to set:
secure_file_priv = NULL
If set to NULL, the server disables import and export operations. This value is permitted as of MySQL 5.7.6.
However, that value doesn't seem to be in MariaDB's docs - https://mariadb.com/kb/en/mariadb/server-system-variables/#secure_file_priv
If I try
NULL in MariaDB 10, I get this error:
[Warning] Failed to normalize the argument for --secure-file-priv.
What do you recommend to prevent import/export operations?
If I set to a given folder, will things like
OUTFILE ../../../etc/my.cnf work? (i.e., relative paths, going level ups)
