5 Server Security Tips to Follow

  • 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:

    If you have more than one computer connected in the home, or if you have a small-office network, it is important to protect every computer. You should have a hardware firewall (such as a router) to protect your network, but you should also use a software firewall on each computer to help prevent the spread of a virus in your network if one of the computers becomes infected.

    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.


    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.
