1. What is an SSH Tunnel?
Understanding SSH Tunneling
An SSH tunnel is a secure method of transferring data over an encrypted connection between a local device and a remote server using the SSH (Secure Shell) protocol. It creates a “tunnel” that allows data to travel securely, bypassing firewalls or security restrictions. Typically, SSH tunnels are used to forward specific types of network traffic, such as HTTP, to a remote server, ensuring confidentiality and integrity. This method is commonly used for accessing internal systems securely, remote administration, or bypassing network restrictions. SSH tunnels are highly secure but usually require manual configuration compared to simpler VPN solutions.
How Does an SSH Tunnel Work?
- You create an SSH connection between your computer and a remote server.
- Your internet traffic is sent through this encrypted connection.
- Any data passing through the SSH tunnel is secure and hidden from third parties.
Common Uses of SSH Tunnels
- Accessing blocked websites: If your internet provider or government restricts access to certain websites, SSH tunnels help bypass those restrictions.
- Secure remote access: SSH tunnels allow you to securely connect to remote systems, making it popular among IT professionals.
- Protecting data from hackers: When using public Wi-Fi, an SSH tunnel can prevent hackers from intercepting your information.
Advantages of SSH Tunnels
