How it works

The vRouter uses a global known hosts database to maintain the public keys of trusted and known SSH hosts. This SSH known hosts database needs to be pre-populated with the trusted SSH public keys of the systems that the vRouter is likely to interact with by means of SSH. The vRouter administrator populates the database. On a connection attempt, if the SSH server public key of a known or trusted host is a mismatch, the vRouter prevents any file or data exchange with the potentially malicious SSH server.
