Using Public Key Authentication with native SSH Applications for Secure Sessions

XTAM’s SSH Proxy provides support for native SSH application such as SSH Shell, PuTTY, Secure CRT, MobaXTerm, ssh.com and others to establish high-trust connections to remote servers by using a personal account (managed by Microsoft AD, eDirectory or XTAM itself) without knowledge of the actual (shared or privileged) account on the destination server. XTAM’s SSH Proxy allows a connection to remote servers using both user/password or private/public key authentication strategies as supported by remote server for this account.

Using the private key authentication mechanism when connecting to remote SSH servers

  • Simplifies access
  • Promotes automation
  • Reduces the number of passwords
  • Increases overall network security

XTAM supports the use of your existing Public/Private key pair or it can generate its own Public/Private key pair. If you already have your own Public/Private key pair that you would like to use with XTAM’s SSH Proxy, please read the next section to enable. If you would like XTAM to generate you a new Public/Private key pair to use with the XTAM SSH Proxy, please jump to the second section.
