After some delay, a new version of OS for our routers has been released. The version is marked as 6.1.8 and it will be either the last or one of the last ones before 6.2.0 hits public (note that 6.2.0 is already in beta as announced in the 6.2.0-beta article)
While only the patchelevel version number has increased, the release is not a pure patchlevel release.
It for sure contains usual load of fixes and security updates, but next to that, there are a few improvements as well. To name a ...
This article main topic is about v2 factory settings and default use case, also discussing a few LAN attacks on high-level.
When you get a cellular router from Advantech CZ, the default settings fall into one of the three cases:
As for the first possibility - router pre-configured exactly to your needs: as described in the first article, there are several ways how ...
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.
New version of firmware for Advantech cellular routers has been released. The release was done for majority of models with usual exceptions (SL302, SR305 and Spectre v2 routers - please see firmware distribution overview).
As a patchlevel release it contains a number of bug fixes and also security fixes (most importantly the OpenSSL library update). Also the stability of v3 routers under very high loads has been improved.
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.
New version of firmware for our routers is available on Engineering Portal.
Except the SR305 and SL302 which are destined for NAM market and thus a firmware change is a subject of certification, the 6.1.6 is available for majority of routers. Details of distributions can be found in the Firmware Distribution overview document.

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 ...

PCN is a name for a specific type of document. The abbreviation means Product Change Notification. It is a kind of a document we issue when there is important change in one or more products we are manufacturing.
Not every change in a product requires a PCN. The documents are here so that we can communicate changes that may have impact on our partners, distributors and customers. Other changes, like, replacing one end-of-life component with equivalent one, may not be significant enough for creating a ...

The Firmware Over-The-Air (FOTA) user module is an additional feature of Advantech routers. This module will assure the correct firmware for cellular module is chosen, downloaded and installed into the router automatically. Only the firmware of the cellular module is updated (not the firmware of the router).
The user module is easy to use – it can be activated with just one checkbox. The router must be connected to the Internet in order to use FOTA updates. The module checks for the new cellular module firmware every 24 hours. It is also possible to check ...
