Memcached is a high performance, in-memory key-value store or caching system. Its main purpose is to speed up web applications by caching database queries, contents, or other computed results. Memcached is originally a linux application, but since it is open-source, it has been compiled for windows.

Memcache vulnerabilities As open-source software, Memcached could be vulnerable to attacks. This became apparent in 2018 when a new form of DDoS attack was launched. Cyber attackers sent spoof requests, which mask the real identity of a sender by cloaking their IP address, to a vulnerable UDP Memcached server.

Is Memcached necessary?

Caching. Memcached is a great choice for implementing a high performance in-memory cache to decrease data access latency, increase throughput, and ease the load off your back-end systems.
