Does IGEL OS verify the firmware package via checksum or hash before actually starting the firmware update?


I assume that this is the case, but I was seeking an explicit answer to make sure. Do thin clients verify the firmware package via checksum or hash before actually starting the firmware update?


Short answer: yes. A broken download will result in a error message!


What if the download is not exactly broken, but not identical to the firmware file specified in the U.M.S.? Does the thin client do anything to verify that the firmware file(s) is indeed valid? Does it use hashes or checksums to verify that they are valid and downloaded correctly?


We use own partitioning system, partitions are compressed, thus data is obfuscated.

In addition, Checksums of IGEL partitions avoid loading of modified code

Our Configuration is written to a dedicated and compressed partition

Laden …

FAIL-SAFE FIRMWARE UPDATE

Firmware updates always finish completely

The device always keeps running

The device always stays bootable

Update process without critical phases

Critical updates always processed by two phases


Thank you for the explanation. To clarify, firmware updates are downloaded to a separate partition that is compressed, and, by virtue of being a separate Igel partition, it is verified via checksum? We’re more concerned with malicious modification (such as a man-in-the-middle attack) than with the inherent stability of the update process.


I have a customer project where I have to grab a little bit deeper into this topic, as soon as I have what I need I will share it with you!
