SSH stands of Secure Shell hosting. SSH provides a safe and secure encrypted
mechanism to login to the system and transport the files. It works like a secure
replacement for FTP (File Transfer Protocol). Once you have created the website
pages, you have to upload the files to the server from the computer and here,
you will need a safe file transfer medium.
Internet is great source to gain and exchange information. Its open architecture allow user to get information at rapid pace. Irrespective of the huge usage and exposure to vast numbers of users, Internet is designed to be stable. Undoubtedly, the openness of the Internet makes it useful and user friendly, but it also subjects it to malicious attack. Some of the very common attacks are stealing passwords or sensitive information, taking over messages to know and change the broadcast data or use of fake network addresses to the full access control mechanism. It can also redirect connections to a fake server. SSH can protect the server and website from all aforesaid attacks and problems. A wise choice is to use a php host with SSH support for avoid problems.
Installation of SSH is extremely easy and offer quick protection. To install SSH, you have to download SSHSecureShellClient-3.2.9.exe file. There are two main fundamental component needed to transfer the files through SSH and SFTP- server validation and client authentication. Both components uses public and private keys to establish authenticate communication between the server and the user. For a completely secure communication, SSH compare the public keys of the server with the public keys saved on the client machine. The public key of server contains a file called "known hosts" which is located on the server where as the public of the client is stored in an encrypted file stored on the local machine.
