Webinar - Build and deploy safer products with new methods of security testing

1 min read

Security testing can be easy with the right tools! With an increase in cybercriminals targeting home/SOHO gateways and Wi-Fi APs, testing has never been more important. In this webinar, you’ll learn how monitoring the behavior of a device under test, by analyzing its live network traffic can help uncover issues that may not come to light with regular penetration testing. This revolutionary testing method validates that your device is following best practices or deployment policies prior to being deployed. Keep reading

3 testing tips for building robust managed devices using TR-181

6 min read

Powerful protocols like USP/TR-369, and its predecessor, TR-069, help the broadband and consumer electronics industries produce devices that can be configured, monitored, and controlled in a standardized way. That standardization means that the implementation of these protocols must be tested to ensure that they conform and will interoperate in the larger ecosystem. In addition to the management protocol and its interface, however, is the underlying implementation and its API into the device’s drivers, applications, and other interfaces. Keep reading

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
