Secure Shell (or SSH) is a cryptographic protocol, which allows the secure use of network devices in an unsecured network. It uses the client-server principle and connects an SSH-supporting application to an SSH server.
SSH usually secures network services like command-lines, logins, and remote commands. Users employ the shell to access remote devices and execute commands there, but they can also use it for secure file transfer. You can access SSH by simply logging in to your SSH account to reach your data.
SSH uses public-key cryptography for authentication. It is a secure method where only users possessing a private key can access the data. In this way, your data is protected from unauthorized access.
An SSH tunnel is the encrypted tunnel created by an SSH protocol. By using this software-based approach, users can transfer unencrypted traffic over an encrypted channel, keeping the data protected.
Due to strong encryption, you can make an SSH client work as a SOCKS proxy. SOCKS is a protocol using a proxy server to route data packets from a server to a client. A proxy generates an arbitrary IP before your data reaches the destination. SOCKS uses proxies to form TCP and UDP protocol connections through IP addresses.
When you combine SOCKS with SSH, the traffic goes through the SOCKS proxy on your local system, and the SSH client routes it through an SSH tunnel, so your traffic appears to be coming from the SSH server.
VPN stands for a virtual private network. It encrypts your traffic and routes it through a remote server, changing your IP location. It protects your online privacy, ensuring that nobody can intercept your traffic, snoop on your data, or see your geolocation by checking your IP.
It has become an essential tool for online security in corporate and private environments. VPNs are easy to use, and most premium services provide their users with top-notch encryption and privacy protection.
At first sight, SSH seems to be similar to VPN services, but there are differences.
Let’s see which of the two is more secure.
While SSH tunneling has some benefits, a VPN clearly wins for an average user. Premium services like NordVPN offer high-quality encryption, accessibility, and a wide range of servers.
