1. Secure the root directory: The root directory contains information about your server and if it gets into the wrong hands, it can lead to disasters. Therefore, protect it with the highest security level possible.
1. Use strong passwords: Make sure all your server’s accounts have strong, complicated passwords to prevent brute force attacks.
1. Regular updates: Apply regular updates to keep your server up to date with the latest security patches.
1. Install a Firewall: A Firewall allows you to control what traffic passes in and out of your VPS, thus creating a robust barrier of protection against hackers.
1. Use 2-factor authentication: This increases the security level of your VPS as even if somebody acquires your password, they would still require a code sent to a different device (like your phone) to gain access.
1. Use SSH Keys: SSH keys provide a more secure way of logging into a server than using a password alone. While a password can be cracked with brute force, SSH keys are nearly impossible to crack by brute force alone.
1. Limit login attempts: By limiting the number of failed login attempts from a particular IP address, you can certainly safeguard your VPS from repeated attacks on your server.
1. Use a VPN: Connecting through a VPN can add an additional layer of security to your VPS. A VPN creates a private tunnel between the user and the hosting server, encrypting any data passed through it.
1. Monitor your server: Regularly check your server for unusual activity and setup alerts for suspicious actions.
1. Regular backups: Don’t forget the importance of regular backups. This helps to recover your data in case of any loss or damage.
1. Use Antivirus Software: Install antivirus software to secure your VPS server against malware and other types of cyber-attacks.
1. Encrypt your data: Data encryption ensures that your data cannot be read or accessed by unauthorized individuals.
1. Disable unused services: If there are services running on your server that aren’t being used, disable them. The more services running on your server, the more entry points there are for hackers.
Remember, securing your VPS server is an ongoing process. Regular audits and constant vigilance are vital.
