 ===== Secure Memcached =====
 Memcached does not have any application authentication, so you should configure the memcached server with firewall rules to only allow certain sources to utilize it on tcp and udp port 11211 (the default port).
+  * Either listen locally, or setup firewall rules to protect the cache.
