I am currently trying to create a small PoC for implementing a UNS using an MQTT broker. Security is our highest priority. Would HiveMQ MQTT broker support Access Control Lists (ACLs)? TIA!

Hi Lili

Yes, HiveMQ definitely supports Access Control Lists (ACLs)! They are great for ensuring that only the right people and devices have access to the right topics, keeping your implementation secure. We actually have a detailed blog post that dives into securing a Unified Namespace (UNS) architecture for IIoT: [Securing the Unified Namespace Architecture for IIoT](https://www.hivemq.com/blog/securing-unified-namespace-architecture-for-iiot)

What other security features are you considering for your PoC? I’d love to help you out with any questions or concerns you have!

TFS! This is useful. I found this article around [Acess Control and Role Based Access Control](https://docs.hivemq.com/hivemq/latest/control-center/configuration.html#access-control) too. If I have more questions, I will come back again.Thanks!
