Answer

The SSH (Secure Socket Shell) protocol protects data in the following ways:

  1. Before transferring data between the client and the host computer, the SSH calls upon the SFTP (Secure File Transfer Protocol) to authenticate both the server and the client machine.
  2. Once the authentication process gets over, the SFTP protocol works on to set a secure channel between the client and the host computer by establishing a secure connection and then only the data transmission is initiated.
  3. SFTP (Secure File Transfer Protocol) protects the integrity of the data using encryption and cryptographic hash function techniques.
