Securing SSH Access on Your VPS

Securing SSH Access on Your VPS

SSH is the primary way to access your VPS. By hardening SSH, you significantly reduce the risk of unauthorized logins.

Step 1: Change Default SSH Port

Edit the SSH configuration file:

sudo nano /etc/ssh/sshd_config

Find Port 22 and change it to another port (e.g. 2222).

Step 2: Disable Root Login

Inside the same file, set:

PermitRootLogin no

Step 3: Use Key-Based Authentication

On your local machine, generate a key pair:

ssh-keygen -t rsa -b 4096

Then copy the public key to your VPS:

ssh-copy-id -i ~/.ssh/id_rsa.pub user@your-vps-ip

Step 4: Restart SSH

sudo systemctl restart ssh

✅ Your VPS is now protected with stronger SSH security.
