If you consider a managed VPS (Virtual Private Server), you will not be burdened by any tasks associated with its maintenance. For a price, you just witness and enjoy how your site consistently grows. If, in this case, you decided to run an unmanaged VPS, you are expected to do all the legwork from software updates to patches and security.
With this, it is important that you are extremely confident of your technical skills otherwise your site will crumble and it will be left vulnerable. With this, it is critical that you keep your server as secure as possible. Where private information or sensitive data is concerned, you have to know security measures to protect your vps kvm.
To help you, here are some tips to protect your unmanaged VPS hosting:
Constantly audit your server
Your first measure is to constantly run an audit of the server. Since you invested on that server, it is just right to know whatever is running on your system including the system vulnerabilities.
The good news is that there are many tools that you can utilize to carry out such audits. You can, for instance, consider a one-time auditing and hardening tool or you can set up an automated and regular auditing system.
Disable unused services
Following the audit, you should look into services and applications that are running on the system. You need to determine if all of the daemons are necessary for VPS to perform. If it is not necessary, you are actually making your server vulnerable. With this, it is always wise to disable unused services.
Close ports that are unnecessary
When it comes to ports, it is a good habit to open ports that VPS only requires. If there are ports that are unnecessary, you are also making your sever vulnerable. The best thing to do is to set the INPUT chain to “drop”. Essentially, this will give you the assurance that any port you haven’t open will be ignored.
Updating everything is basic but sometimes you blatantly ignore it. Always remember that updating is crucial in keeping your server secure. This is because the latest versions of OS contain security patches for the vulnerabilities encountered by the older ones.
Make backups often
Aside from updating, you should also make backups as often as you can. This is a no-brainer: when something goes wrong, you still have access to your information or data. By making backups, there is a lesser risk of data loss.
Finally, you should be wary and remain vigilant. By remaining vigilant, you can guard your system against the possibility of unanticipated security threats. Do not forget to run regular malware/virus scans and check security logs.
Aside from security, you should also look into the flexibility of the VPS hosting when it comes to scaling. A good VPS hosting provider can accommodate your needs if they change over time. Finally, you should look into customer service and tech support teams that can respond diligently and quickly when unexpected problems arise.
