SMB 3.1.1 is the state of the art for secure remote file access, but deploying it for clouds and mobile users can be very challenging; TCP/445 is often blocked, networks are often slow, and edge file servers are often feared. The Microsoft SMB3 team has now built the first implementation of SMB3 over QUIC, a UDP/TLS transport pioneered by Google. This allows secure tunneling of SMB3 over internet-friendly ports. Furthermore, we have added compression for SMB3, which allows significant data savings over congested and low bandwidth networks. In this talk we’ll discuss these new options, as well as other recent security and feature capabilities nearing completion.
