We released a user module with NetFlow/IPFIX probe and collector. The module captures a source and a destination IP address of each observed network communication and the amount of data exchanged. This can be used by network monitors such as PRTG to identify unusual traffic flows caused by misconfigurations, security incidents or policy violations.
Detailed description of the module configuration and operation can be found in the NetFlow/IPFIX Application Note.
The User Modules can be downloaded here.

This security advisory is a reaction on the recently discovered network vulnerabilities in Linux kernel (see below on particular names and links).
These vulnerabilities can, under certain circumstances, be used by an attacker against a range of our routers running current firmware (6.1.9) with the potential result of the router rebooting.
We have already prepared a patch which closes the vulnerabilities. The patch will be included in future firmware versions (6.1.10, 6.2.0) when these are released.
Until the new firmware versions are available, you may apply any of the recommended workaround. The easiest ...

A very important topic to cover in this article series is something we call security model of the router.
Before getting to that, let's look at the user model. There are a few user models being used in the operating systems based on Linux. Please note that this definition is something to make our security model more understandable and help with further understanding of the securing process, it is not a formal definition as used in information science.

You are about to read the first article in the series of articles about securing our routers. The series is tailored to our router devices, teaching and showing some general and specific principles and also describing possibilities and use cases. While some of the knowledge here is usable also outside of the router devices, you should keep in mind that we are focusing on our cellular routers running Conel OS 6.x here.
This first article is a basic building block. We are going to describe the device and its basic characteristics and possibilities of accessing the device with an accent on security. Also, some basic use cases are to be touched here and the terminology used for the rest of the series established.

Some time ago there has been questions about impact of IoTroop/Reaper Malware on our devices. A week ago there has been another inquiry. As it seems to be an (unexpected) pattern, this short information announcement is given to public.

It has been some time since we implemented and enabled notifications on the Engineering Portal. The notifications are primarily meant as something extra for our distributors and partners (as it requires an account on EP), but for example the RSS can be used by anybody without an account needed - read on.
The notification system we have is, thanks to the tagging system we use for all products and documents, quite unique however it could take some time getting used to. Also, we are still ...
