When it comes to servers in general, there is always something on your mind. For example, you may be in the process of learning more about server virtualization.
If you have your own server, it’s imperative to understand how to keep it secure at all times. While this sounds like a complicated task, there are some basic steps you can take to ensure that you don’t make any mistakes.
Here are five security tips that will give you peace of mind:
1. SSH Keys
With SSH, any type of authentication, such as password authentication, is encrypted. When you compare this to password based logins, it’s easy to see that it is much more secure. The reason for this is simple: with a password system, malicious users can continually attempt to access your server.
2. Firewalls
In short, a firewall is nothing more than a piece of hardware or software that controls the services that are exposed to the network. With this, you have the opportunity to block access to ports that should not be publicly available.
Microsoft shares an interesting view on the use of firewalls in a small office environment:
As you can see, the use of both a hardware and software firewall is essential.
3. Watch for Trouble
If you notice anything wrong with your server, it’s time to take immediate action. You don’t want to sit back, wait for something worse to happen, and hope that it doesn’t have a negative impact on your network.
If you recognize trouble but don’t know how to find a solution, consult with an IT provider. It can be frustrating to find yourself in this position, but it’s better to consult with a professional than to assume you can solve the issue on your own.
4. Intrusion Detection System
This one piece of software can put your mind at ease. This is designed to monitor a network or system for unauthorized activity. With this in place, you never have to worry that something will slip through the cracks.
Once you learn more about an intrusion detection system, it’s safe to say that you’ll want to take full advantage without delay.
5. Keep Your System Updated
Many people overlook the importance of doing this. It’s a must that you keep your system updated, with a focus on security fixes and the latest releases. It’s easy to fall into the trap of overlooking this step, but you don’t want to go down this path.
Conclusion
There is a lot to think about in regards to server security. If you’ve yet to implement the five tips above, now’s a good time to change your approach
Once you have a system in place for keeping your server secure, you’ll feel better about your ability to do so in the future.
