Tip: Secure web hosting is extremely important these days with all the hackers as fishers out there. A few critical criteria that is required for security is SSL and SSH. SSL is short for Secure Sockets Layer, a protocol for transmitting private documents across the Internet. SSL uses a cryptographic system that uses two keys to encrypt data, a public key known to everyone and a private or secret key known only to the recipient of the message. SSH is shot for Secure Shell and provides strong authentication and secure communications over insecure channels. When using Secure Shell the entire login session is encrypted.
