After memcache is installed, the server is attacked by ddos

after downloading memcache from the Internet, installing it to the server, it was later attacked by ddos. I don"t know if the two are related. If so, what are the measures? Using a win server

listening on 127.0.0.1 would be fine. Ddos has nothing to do with this. It depends on what ddos is.
