Security: Secure Shell
If you are concerned about the security of your data, especially over the wireless portion of your network, you may want to prevent your business critical data from being snooped or stolen. Our terminal emulation and web Browser has built-in support for Secure Shell protocols to provide strong data encryption and user authentication. This ensures confidentiality, authenticity and integrity of data exchanged between the handheld terminal and your host application.
Depending upon your requirements, you may select from Secure Shell SSH, Secure Sockets Layer SSL or HTTPS, which is the standard security protocol used with web browsers. Using either of these security protocols will allow you to deliver productivity solutions for your mobile workforce without compromising your organization’s data or business systems.
SSH
SSH, or Secure Shell, is a popular, powerful, software-based approach to network security. Before data is sent by our application over a network, it is automatically encrypted (scrambled) by SSH. The data is automatically decrypted (unscrambled) when it reaches the host. The result is transparent encryption: users can work normally, unaware that their communications are safely encrypted on the network. In addition, SSH uses modern, secure encryption algorithms and can be found within mission-critical applications at major corporations.
SSH is applicable only when connecting to VT host applications. It prevents against the following security concerns:
- Password Exposure:
- Eliminates the risk of password exposure in transmission of data between the handheld terminal and your VT host. When configured for SSH, our VT emulation sends passwords over the network in encyrpted format, making it impossible for outsiders to "sniff" the passwords.
- Man in the middle attack:
- A man-in-the-middle attack consists of attacker residing between the client and server and intercepting or modifying communications. With our SSH, both client and server can authenticate and make cryptographic integrity checks to ensure that the transferred data has not be modified.
- Data Eavesdropping:
- With our SSH support, you prevent eavesdropping of confidential data, as it is encrypted while it travels over the networks. It also ensures that only the legitimate recipients can access the transmitted data.
SSL
SSL or Secure Sockets Layer provides secure encryption of data between a handheld terminal and the host. It is the underlying security protocol used by web browsers. With SSL, they host system can also ask for a password to authenticate. This is sent over a secure encrypted connection.
SSL is easier to manage and provides comparable security to SSH. However, some companies are mandated by policy or federal law to use SSH. We recognize this need and have therefore provided integrated support for SSH within our products.
SSL may be used for secure connection to any 5250, 3270 or VT host.
https
https or secure http, is the standard protocol used by Web Browsers for a secure communication of data such as payment transactions. It ensures reasonable security from eavesdroppers and "man in the middle" attacks when using a web browser.
If you have ever gone through the process of purchasing anything over the web, you most likely have used https protocol to protect your credit card and personal data. Our Web Browser supports this same level of security as is available on desktop web browsers.
https may be used for secure connection for web applications.
