What operating system and services are you running? Is this a web server? We will need a bit more information before we can suggest some security tips.
Depending on OS, DO tutorial section has a getting started guide.. I followed the same for my VPS..
Then I followed the guides available on the software and services that I installed to further secure those.. Like MySQL / HTTPD and such..
I dont think there is any universal guide..
Operating system running on server :- Windows 2012
Here following list of service will be running.
ADDS
DNS
WDS
File and storage services
FTP
IIS
Apache tomcat
MySQL server
MSSQL Server 2012
URL rewrite module
Windows server backup
VisualSVN server
I suggest take a look at CIS Benchmarks
https://benchmarks.cisecurity.org/downloads/multiform/index.cfm
You will find detailed instructions on how to harden different operating systems and webservers like Apache as a matter of fact you can use the same benchmarks to build your puppet modules just for security.
