SFTP is one of several options for shielding that data in transfer, to make sure that hackers don't obtain it, and that the company does not unwittingly perform a HIPAA violation if that law applies. That’s why SFTP can be useful in securing this type of data. One of the biggest ones is to comply with standards like the federal Health Insurance Portability and Accessibility Act (HIPAA) act that governs protected health information.Īny business, even a third party working with a hospital or healthcare provider, must keep its PHI confidential, and that includes during its transition through networks in digital packet form. SFTP as a successor to FTP is used for many situations where file security is important. Only when the SSH key pair matches then authentication can occur. One half of the SSH key is stored on the computer of the two clients, while the other half is loaded on the server and associated with their account ( public key). The SFTP protocol is initiated only when the user uses the SSH to log into the server to avoid leaving additional ports exposed or maintaining additional authentications.Īn SFTP server requires both communicating parties to authenticate themselves either by providing a user ID and password, or by validating an SSH key (or both). Requests can be processed asynchronously. The client identifies each operation with a unique number that must match the server response. The SFTP protocol runs over the SSH protocol using the normal SSH port 22 and supports multiple concurrent operations. The latter option makes use of a program that abstracts the use of SFTP visually for end users. In the first type of setup, the user has to type in specific command lines to generate the SFTP protocol, usually in a Linux environment. SFTP is a client-server protocol that can be launched either as a command line or through a graphical user interface (GUI). Techopedia Explains Secure File Transfer Protocol This term is also known as Secure Shell (SSH) File Transfer Protocol. A private user may want to encrypt his or her communications as well. So a business user might use SFTP to transmit files containing trade secrets or other similar information. For example, trade secrets may not be covered by any particular data privacy rule, but it can be devastating for them to fall into the wrong hands. SFTP can be handy in all situations where sensitive data needs to be protected. Since the client needs to be authenticated by the server, SFTP also protects against man-in-the-middle attacks.
#SSH SECURE FILE TRANSFER CLIENT PASSWORD#
SFTP transfers files security using SSH and encrypted FTP commands to avoid password sniffing and exposing sensitive information in plain text. SSH and SFTP were designed by the Internet Engineering Task Force (IETF) for greater web security. Secure Shell is a cryptographic component of internet security.
