6 Security Best Practices to Prevent Attacks on Your Dedicated Server

Upgrading to a dedicated server is an excellent step for getting more resources through your website, apps and database. Before doing this, you should keep in mind that cyber threats are still possible. That’s why it’s important to secure the future hosting plan. Here are 6 best practices to start!

1. Limit the root access

Every operating system creates a root user that has administrative rights. While this helps you doing configurations, it’s best to avoid using the same access most times. Otherwise, the risk of compromising the whole server is bigger. It’s better if you create another user with restricted permissions and use sudo when needed. The main account can be blocked, so you limit the attempts of brute force. If you have employees, they should also login only using trusted networks. 

2. Maintain the database

A database is a vulnerable point of entry for cyber attacks. For the same reason, it should be a priority to take security measures against SQL injections and restrict the user’s interaction where it is not required. This matters even more when you collect sensitive information about customers. To make things easier, you will find administrative tools online that are built for the same purpose.

3. Perform regular scans

There are many sorts of malware, trojans, spyware or viruses that can affect the operating system. If you want to prevent their actions, you should use a premium software that will detect and isolate all malicious files before they cause any damage. This way, your dedicated server will be scanned regularly for any potential threat.

4. Change the default SSH port

Many hosting services run on the standard SSH port. Usually, it has the number 22 and hackers scan the software to see if you’ve changed it. Fortunately, you can do this with any number, being recommended to use one port bigger than 1024. This will keep the access hidden from bots, since they rarely look in such ranges. Just be sure you don’t already use the new port for another activity, because you will create a crash. 

5. Remove the programs you don’t use

It’s easy to forget about most apps on your server, because you’re not using them. However, they can quickly become a vulnerability. If you just install a program for a task, then you don’t need it anymore, make sure it is deleted. This is a great solution to maintain the whole server clean and stop bad consequences.

6. Explore managed services

Compromising on security can cost you lots of money in the long term. If you don’t have the time or expertise to do most changes, consider hiring professionals. They will take care of the whole computer in exchange for a monthly fee. Manually securing your dedicated server can be overwhelming for beginners. An investment will be beneficial, especially if you don’t already have a small IT team.

Is a dedicated server safe?

A dedicated server is generally safer than a VPS or shared hosts, because it provides isolated resources and there’s no other user on the same computer. On the other hand, you should make a few configurations when you buy one. Follow the above tips and you’ll get over this challenge.
