1. Regular system updates: Always keep your system updated with the latest software patches and releases.
1. Install a Firewall: Restrict access to your server by implementing a good firewall and setting up appropriate access rules.
1. Carefully manage users: Limit access rights and privileges based on the user role. Use strong passwords for all the users and do not use default usernames.
1. Use SSL: If you’re dealing with sensitive information, ensure your server’s communication is encrypted with SSL.
1. Two-Factor Authentication (2FA): Implement 2FA for accessing your server. This adds an extra step for anyone trying to access your server.
1. Audit your Server: Regularly monitor and audit your server’s activity logs to identify any potential security threats or suspicious activity.
1. Use a dedicated IP: Use a dedicated IP address and avoid sharing it with others. Shared IP addresses can become a security risk.
1. Disable root login: For Linux servers, disable the root login to prevent potential hackers from gaining high-level access.
1. Use secure remote login methods: Instead of remote logging in through root, create a standard user with sudo access. This user can then elevate to root access once the login is secure.
1. Install security processes and modules: Use processes such as ModSecurity (for web servers) and SELinux (enforcing access control policies).
1. Backup Regularly: Regular backups can help recover from possible attacks or breaches.
1. Install Anti-Virus: Use a robust antivirus solution to prevent possible malware threats.
1. Review your server periodically: Server requirements and technologies are invariably changing. Regular reviews ensure your server’s security is up-to-date.
1. Control physical access: If your VPS is on your premises, implement strong physical security measures to prevent unauthorized access.
Remember to keep a close eye on emerging security trends and threats. Implementing these precautions will go a long way in securing your VPS server.
