This is state of the art for systems software now – which is not all that impressive.
Glantz explained that Ikea has more than 3,500 Red Hat Enterprise Linux (RHEL) servers deployed in Sweden and around the world. With Shellshock, every single one of those servers needed to be patched and updated to limit the risk of exploitation. So how did Ikea patch all those servers? Glantz showed a simple one-line Linux command and then jokingly walked away from the podium stating “That’s it, thanks for coming,” as the audience erupted into boisterous applause. On a more serious note, Glantz said that it took approximately 2.5 hours to test, deploy and upgrade Ikea’s entire IT infrastructure to defend against Shellshock. Eweek.
