Understanding SSH is an acronym for Secure Shell which is a network protocol that utilizes cryptography to communicate data on network devices to be more secure. In the concept of the use of SSH must be supported by a server or device or client computer that exchanges data. Both must have a server-side SSH server and a client SSH for the recipient computer (the client). The number of network security issues is indeed a serious thing to deal with, especially for networks that connect crucial data exchanges. For example banking, government, and private institutions that need data protection for consumers and their businesses, even the best antivirus can not provide perfect protection.
