Advanced SSH Security and Key Management

Implement enterprise-grade SSH security practices to protect your VPS.

Use SSH Keys Instead of Passwords

SSH keys are significantly more secure than passwords.

1. Generate an SSH Key Pair

ssh-keygen -t ed25519 -C "your_email@example.com"

2. Copy Your Public Key to the Server

ssh-copy-id youruser@your_server_ip

Harden SSH Server Configuration

Edit /etc/ssh/sshd_config and apply these settings, then restart the SSH service:

PermitRootLogin no
PasswordAuthentication no
