MQTT security

MQTT!Broker

CONNECT with username / password

SSL/TLS TCP/IP

- MQTT spec doesn’t define security model aside from username/password authorization on connection

- Brokers *can* implement support for SSL/TLS and policies for connection and messaging

ex. organize topic space by “group” username associated with a group

bboyd is in group “IBM” and can pub/sub IBM/bboyd/#
