FAQ

To ensure the highest levels of security, Rafay recommends that remote SSH access not be enabled on the Rafay VMs. SSH type of access is not required for any operations performed by administrators. The Rafay Controller provides a zero trust, remote diagnostics and control channel that can be leveraged securely as long as

  • The VM is operational and
  • The VM has network connectivity to the Controller.
