Where 6379 fits
Why 6379 is special
Redis was designed for trusted networks and historically shipped with no authentication, so an exposed 6379 was for years a direct route into a server rather than merely a data leak. Later versions bind to localhost by default, which is a fix at the level of the default rather than the protocol.

Redis was built for use inside a trusted network and long shipped without authentication, so an exposed 6379 offered command execution rather than merely data. Later versions bind to localhost by default — a fix at the level of the default rather than the protocol.
