MySQL 9.5 Reference Manual Including MySQL NDB Cluster 9.5
    The following sections describe the
    INFORMATION_SCHEMA tables associated with the
    MySQL Enterprise Firewall plugin (see Section 8.4.8.1, “The MySQL Enterprise Firewall Plugin”). They provide
    views into the firewall in-memory data cache. These tables are
    available only if the appropriate firewall plugins are enabled. Like
    the firewall plugin, these tables are deprecated, and subject to
    removal in a future version of MySQL.
  
    These INFORMATION_SCHEMA tables are
    not used or supported by the MySQL Enterprise Firewall component.
