Consult this section before deploying the
InnoDB memcached plugin on
any production servers, or even test servers if the MySQL
instance contains any sensitive information.
Because memcached does not use an
authentication mechanism by default, and the optional SASL
authentication is not as strong as traditional DBMS security
measures, make sure to keep only non-sensitive data in the MySQL
instance using the
memcached plugin, and wall off any servers
using this configuration from potential intruders. Do not allow
memcached access to such servers from the
Internet, only from within a firewalled intranet, ideally from a
subnet whose membership you can restrict.
