Re: [mqtt] can i set different publishing permition for each topic?

[Nick O'Leary]

Hi,

this mailing list is about the MQTT protocol, not individual implementations.

What you're asking will be specific to whatever broker implementation you are using. So you should either say what broker you are using, or direct your question to the appropriate support forum of that implementation.

Thanks,

Nick

 As an example, an implementation such as the IBM Watson IoT MQTT broker has structured the topics so as to allow segregation of devices, i.e. it can be setup so that a given device (client) needs to be authenticated and can publish and subscribe only to a specific set of topics. Gateway client connections can be used to group access to devices. While at first sight this might seem restrictive, it actually allows for a much better control of what happens on the broker.

We have recently added permissions to each client that connects like  read/ write , read only and write only to our IOT Platform.  Check out the platform running at www.mqttserver.com But your requirement seems to be a more enhanced version of the security. 

We can add it as a custom implementation over the current implementation.

Most of the full featured production grade MQTT brokers would have Access Control List for enforcing the connect, publish and subscribe access control lists with varying degree of sophistication in terms of how fool proof and feature packed they are. For example, the ACLs would allow wildcards for enforcing the rules for publish / subscribe and allow CIDR based IP range for connect ACLs. Advanced ACLs for pub / sub would also provide the flexibility for negating an ACL to handle exception to the ACL rule. For generic information on the feature you can refer IoTSecurity & ACL.
