Security Issue: Memcached

Install / Update Security
1

Dear Community,

As per default configuration, memcached on CentOS 6 and CentOS 7 listens on all IPs and thus is accessible from outside if your server’s firewall is not restrictive by default.

You can secure memcached by editing the file /etc/sysconfig/memcached and replacing the line

OPTIONS=""

with

OPTIONS="-l 127.0.0.1"

Then restart memcached,

service memcached restart

New installations will configure memcached to listen on only localhost.

Sugestion: please add new category Security and tag this kind of posts.
Is nice practice pinn it globally, but is only temporary solution.
Then most of the security post stay in grey …
I hope, this can improve the transparency of detected problems …
