If the full image update fails due to power failure or poor network connectivity, the device automatically rolls back to the previous working state.ĭevelopers like the ability to use the same mechanism to update the Linux kernel as well as applications, according to Ralph Nguyen, head of community development.

It’s a block-based rather than file-based system, which enhances robustness by eliminating the risk posed by different file versions or only partial updates.

It’s currently an on-premise solution, with a hosted version still in beta. Mender consists of a management server and client device, both under the Apache License, Version 2.0. “So we decided it was time for somebody to build an open source updater that everybody can use.” That seems wasteful and leads to instability of devices because it’s a difficult thing to get right,” said Eystein Stenberg, Mender chief technology officer and co-founder. About half the people we talked to had no way to do updates at all, which is scary the other half had built their own homegrown updater. “When we started out, there was no standard way to do software updates in IoT devices. San Francisco-based Mender provides an open source over-the-air (OTA) software updater for connected Linux devices focused on security, robustness and ease of use. The cyberattacks on Tesla and Jeep Cherokee embedded devices have made clear the security risks associated with the Internet of Things, not only of having systems commandeered but “bricked” - made useless as the malware strain BrickerBot does in a permanent denial-of-service attack.īetter updating of software would certainly help mitigate against such attacks, though updating remote devices can be tricky, due to bandwidth and processing restraints.
