Appendix: Mocana NanoSSH Features and Benefits
Executive Summary
Earlier network-related programs, such as ftp (for file transfers), telnet (for remote logins), and rsh (for remote command execution) lack a basic security mechanism: encryption.
Without encryption, users of such programs are vulnerable to eavesdropping, connection hijacking, and other attacks as they inadvertently expose all transmitted data, including passwords, to almost anyone who’s interested.
That’s why SSH was developed.
One of the more ubiquitous communications protocols, Secure Shell (SSH) is a software approach to network security.
SSH enables secure logins and command execution over unsecured networks and between untrusted hosts.
In addition to keeping user passwords secret, SSH enables tunneling and port forwarding over secure channels, as well as Secure FTP file operations.
So why would any device maker or application developer not include SSH in their product? There are several common misconceptions: "security isn’t necessary for non-PCs," "security causes performance issues," "security is too expensive and difficult," or "security can’t be included on resource-constrained devices."
All of these are myths, especially when you’ve got NanoSSH™ to work with.
NanoSSH is Mocana’s super-fast, super-small SSH toolkit specifically designed to speed product development while providing best-in-class security services for resource-constrained environments like connected devices.
NanoSSH is accelerated and optimized for embedded device security.
It’s easy to use. And it’s surprisingly affordable: the NanoSSH total cost of ownership is usually far less than that of “free” open source SSH packages. (More on that later.)
NanoSSH is already installed on millions of devices worldwide.
