Step-by-Step Guide
1 Initial System Update
After connecting to your fresh server, immediately update all packages with apt update && apt upgrade. This ensures you have the latest security patches.
Pro Tips:
- Set up automatic security updates
- Reboot if kernel was updated
2 Create a Sudo User
Never run services as root. Create a regular user with sudo privileges using adduser and usermod -aG sudo. This limits damage from potential compromises.
Pro Tips:
- Use strong passwords
- Consider key-only authentication
3 Configure SSH Security
Disable root login and password authentication in sshd_config. Use SSH keys for authentication. Consider changing the default port.
Pro Tips:
- Generate SSH keys with ssh-keygen
- Use Ed25519 keys for better security
4 Set Up Firewall
Enable UFW (Uncomplicated Firewall) and only allow necessary ports. Start with SSH, then add HTTP/HTTPS as needed.
Pro Tips:
- Always allow SSH before enabling firewall
- Use ufw status to verify rules
