Security for VPS

[attila]

Hello,

Just got a small VPS.
Any advice on how to secure it? I was reading that Fail2ban is a must.
Any recommendation on a firewall for Centos ? The VPS will not have any control panel installed.

Thank you !

Installing CSF would be a good starting point:

https://configserver.com/cp/csf.html

This will give you a firewall and brute force detection that Fail2Ban would provide along with many other monitoring options if you wish to configure them.
