VPS hosting is a physical web server that is partitioned into multiple hosting environments using hypervisor and virtualisation technology. This way, with VPS in Singapore, users enjoy an independent, isolated environment irrespective of the virtual sharing of space.

Linux VPS hosting offers control over and above what you get with shared hosting. However, this control and virtual sharing can impose security risks,  if the server is mismanaged. Let us share some tips to help you overcome such vulnerabilities and enjoy the best web and domain hosting in Singapore for your businesses.

Best Tips to Secure Linux VPS

1. Don’t Login as Root User

When you buy a VPS Linux hosting, “root” is the default username, a vulnerability hackers are familiar with. Hackers use this default setting to target and guess your password.

Therefore, disable and change it to something else to create an extra layer of security. This will help you  secure your Linux VPS against brutal cyber attacks.

2. Keep Software Updated

With every update, whether in an OS or software, the developers fix security patches and bugs, protecting users from potential threats.When you don’t update your software, you leave room for hackers to inject bugs, making your Linux VPS hosting server vulnerable. So, it is extremely important to keep your software fresh and updated.

3. Work with Reliable Web Host

Ensure you buy Linux VPS hosting from a web host that prioritises security and offers comprehensive security measures. Some of the best VPS web hosting services offer security measures like free SSL certification, Firewall, DDoS protection, malware scans, automated backups, etc.

4. Change SSH Default Port

For remote access to your Linux VPS server, SSH is installed with the default port 22. Hackers use this information to scan servers to open ports like 22 and gain access to SSH, which they use to inject brute force attacks and guess credentials.

To protect your web server, you can move your SSH to a different port. When you change your port, the hackers will see nothing when they scan port 22, keeping your web server safe.

5. Keep Close Eye on VPS Server Logs

Your Linux VPS server logs offer records of all your web server’s activities. Keeping a close eye on them helps you detect any unusual patterns of threat coming your way. It also helps with the early detection of threats before they turn into something big.

6. Limit User Access

When you limit access to your Linux VPS hosting, people get limited but needed access to information. This automatically decreases the risk of unauthorised access, breaches and vulnerabilities, ensuring only trusted users have access to sensitive resources.

7. Build an Internal Firewall

IPtables act like an internal firewall that controls the traffic that goes in and out of your web server. When you filter and set rules on IP packets, you can control which connection you need to allow and which you need to block. This effort acts as an extra layer of protection against cyber attacks.

Note: Ipatable is a command line utility for configuring the rules of Linux VPS kernel firewall.

Conclusion

VPS security is an extremely critical aspect and can get scary if not taken care of. These simple tips can be really helpful in terms of security when you buy VPS hosting.

Security breaches have caused significant financial losses, damaged reputations, threatened data and, worst of all, made businesses shut down.

Therefore, be proactive and adopt all the above tips to ensure the best Linux VPS hosting security.
