How to Telework Securely Using SSH2 Tunneling, SecureCRT, and VShell

The COVID-19 virus has created a need for people to be able to telework securely. While many larger organizations already have a VPN set up, many smaller- and medium-sized organizations do not. Port forwarding (or tunneling) over an SSH2 connection is a way to secure TCP/IP traffic and is simpler to set up than a VPN.

Types of data that can be securely tunneled include:

  • RDP
  • Email
  • VNC
  • Web applications (HTTP)
  • Clients that use remote databases (e.g, Salesforce, SVN and Git, bug tracking tools)

Here are a couple of ways VanDyke Software employees who work from home use SSH2 port forwarding:

  • Securely access a work computer by tunneling RDP traffic using SecureCRT and a VShell server that is behind a firewall
  • Run local email, SVN, and bug tracker clients, which can securely access remote databases by tunneling IMAP/SMTP and other TCP traffic using SecureCRT and a VShell server that is behind a firewall

To help you learn more, we created an online white paper, Tunneling with Secure Shell

This white paper:

  • Examines threats addressed by tunneling over the public Internet or a company intranet
  • Explains how SSH port forwarding, authentication, and access control features work
  • Illustrates common applications like email, file sharing, and screen sharing as they are tunneled over residential broadband and WiFi networks
  • Considers security implications and where tunneling is best used
