Finally. You got the dedicated server you always wanted. Now you’re a real webhost. No more reseller accounts. Yeah …. . BUT – now all the responsibility in keeping that server up and running is up on your shoulders. The very first things after getting your server is to make it secure.


But how do you do that? If you are an experienced Linux system admin this will be a piece of cake. But if you are just Joe Average and know only a little Linux this can be quite a challenging task. You can buy a book and read up on it but that takes time.
 

Surviving a DDoS attack can be really challenging and overcoming the bad exposure you’ll have gotten and/or explaining the downtime and disruption to your customers isn’t easy either. So taking the necessary steps to have a secured dedicated server is evermore incredibly important to your dedicated hosting environment.

So do you know how to secure your dedicated server?

Here’s a quick checklist to help you secure your Linux server:

SYN Cookies – These are helpful because they deny any connections that are not verifiable

Firewalls – Just like on your home computer, server firewalls are meant to prevent malicious attacks and to keep your information safe. However, don’t let a firewall ease your fears, as many DDoS attacks are becoming too complex for even the best firewall to prevent.

Switches – These can limit, prevent, and filter the DDoS attacks and also alert you to their presence, which is a great help as you try to recover.
