CONNECTION_CONTROL

This plugin will check all the incoming requests of connections and, based on that, add a delay in the server response if required. This plugin uses some system variables for configuration, and status variables for monitoring purposes. It also uses some other plugins, event classes, and processes, like audit plugin, MYSQL_AUDIT_CONNECTION_CLASSMASK event class, MYSQL_AUDIT_CONNECTION_CONNECT, and MYSQL_AUDIT_CONNECTION_CHANGE_USER processes for checking whether the server should have added a delay before attending any client connection:

CONNECTION_CONTROL_FAILED_LOGIN_ATTEMPTS

This plugin implements uses of the INFORMATION_SCHEMA table to provide details on monitoring of the failed connections.
