Description

Memcached is a general-purpose distributed memory-caching system. It is often used to speed up dynamic database-driven websites by caching data and objects in RAM to reduce the number of times an external data source (such as a database or API) must be read. The Memcached port (11211) is open on your virtual machine and allows all incoming traffic from the Internet. In order to keep security best practices and decrease the risk for malicious activities, you should restrict access to be only from allowed IP addresses.
