Security is critical when managing your own server. Best practices include:
-
Change the default SSH port from 22 to a custom port.
-
Disable root login and create a separate user with sudo privileges.
-
Install a firewall like UFW or CSF.
-
Regularly update your operating system and software packages.
-
Enable fail2ban to block suspicious login attempts.
-
Set up automatic backups to recover quickly in case of compromise.
With VPS hosting, you are responsible for your own security, so make it a top priority.
