12 VPS Security Tips to Protect Your Server

Understanding and addressing VPS security weaknesses is essential for protecting your server from cyber threats, data breaches, and performance disruptions.

Let’s go through this article to discover 12 essential VPS security tips to protect your server, and ensure robust VPS protection.

1. Change the Default SSH Port

Modifying the default SSH port from the standard 22 to a non-standard port is a fundamental VPS security tip that significantly reduces exposure to automated attacks and unauthorized access attempts.

This proactive measure enhances your VPS server protection by obscuring the entry point commonly targeted by malicious actors.

How to Change the Default SSH Port

To change SSH port in Linux server, follow these steps:

• Open the SSH configuration file using a text editor.
• Locate the line #Port 22, uncomment it by removing the #, and change 22 to your desired port number.
• Save the changes and exit the text editor.
• Adjust your firewall settings to allow traffic on the new port.
• Restart the SSH service to apply the changes.

By implementing the above steps, you enhance VPS server protection, making unauthorized access more challenging for potential attackers.

2. Disable Root Login

Disabling root login is a pivotal VPS security tip that fortifies your secure VPS by preventing unauthorized access to the root account, thereby mitigating potential security breaches.

How to Disable Root Login?

To disable root login in Linux, access the SSH configuration file, typically located at /etc/ssh/sshd_config.

Within this file, locate the line #PermitRootLogin yes, uncomment it by removing the #, and change yes to no. Save the changes and restart the SSH service to apply the new configuration.

By implementing these steps, you enhance your VPS server protection, ensuring a more secure environment against unauthorized access.

3. Implement a Strong Password Policy

Establishing a robust password policy is a cornerstone of VPS security, serving as a formidable defense against unauthorized access and potential breaches.

How to Enforce Strong Passwords on Your Server?

To implement a strong password policy on your server, configure your system to require passwords of sufficient length and complexity, incorporating a mix of uppercase and lowercase letters, numbers, and special characters.

Additionally, consider setting up password expiration policies and educating users to change Linux VPS Password and change Windows VPS Password.

It increases the importance of unique, non-repetitive passwords to further bolster your Secure VPS server.

4. Adopt SSH Keys Over Passwords

Transitioning from traditional password-based authentication to SSH key-based authentication is a pivotal step in VPS hardening, significantly enhancing your VPS server protection.

This method employs a pair of cryptographic keys—a public key and a private key—to establish a secure connection, thereby mitigating the risks associated with password theft and brute-force attacks.

This proactive approach is a crucial component of VPS Security Tips to Protect Your Server, ensuring a robust defense against evolving cyber threats.

How to Generate and Implementing SSH Keys?

To generate an SSH key pair on your local machine, utilize the ssh-keygen command, which is available in most Unix-like systems.

This command creates a public and a private key; the public key is placed on the server, while the private key remains securely on your local machine.

It’s imperative to protect your private key with a passphrase to add an additional layer of security.

Once the keys are generated, copy the public key to your server’s ~/.ssh/authorized_keys file. This action authorizes your local machine to access the server without the need for a password.

You can create SSH Key in Windows or setup SSH Key on Linux to adopt SSH keys and secure them with a passphrase.
It bolsters your Secure VPS against unauthorized access, aligning with best practices for VPS security.

5. Configure and Use a Firewall

Implementing a robust firewall is essential for VPS security, serving as a formidable barrier against unauthorized access and malicious activities.
