Features of the Device 2.12 data model for TR-069 and USP

6 min read

In alignment with the release of TR-069 Amendment 6 and the User Services Platform/TR-369, the Broadband Forum updated its comprehensive data model that describes CWMP endpoints or USP agents. There’s a number of new features, some of which are tied to updates to CWMP, as well as new interfaces and applications that are managed by CWMP or USP. Here’s a short overview of the changes in Device:2.12. How do data models work? Keep reading


Managed IoT, security, and the User Services Platform

2 min read

The team here at QA Cafe is deeply involved in networking standards, especially the Broadband Forum and the TR-069 protocol. The Broadband Forum is expanding the reach of TR-069 with its User Services Platform, representing an evolution of TR-069 to managed a more varied and greater number of connected devices. As consumer electronics vendors enter the world of network connected devices, and networking vendors begin to enter the world of smart devices, there’s a lot of new challenges that management systems can solve.

Are your devices user interfaces vulnerable to common attack vectors?

7 min read

Security in home networking devices, particular home Wi-Fi routers, has come to the forefront in the last few years. While many of the discovered vulnerabilities are zero-day (meaning they are new vulnerabilities that can be exploited before they are known), some of the more recent attacks including VPNFilter, are exploiting common weaknesses in consumer router design that have been well known for some time. Security requirements vs. best practices Keep reading


What is IR-181 and how does it apply to TR-069 testing?

4 min read

Critical to testing TR-069 implementations is the ability to demonstrate that the underlying code that configures settings on the device interacts correctly with the commands sent via CWMP. We discussed this in another training article on setting up Wi-Fi using TR-069, but there are many more valuable tests of this kind to consider. Consequently, TR-069 testing should include some manner of “real-world” testing that can be used to demonstrate the interoperability of the deployment of an ACS and TR-069 enabled CPE. Keep reading
