Embedded RTOS Maker Raises Linux Security Issues

drquizas writes "Embedded RTOS provider Green Hills recently delivered an address where they raised the question of whether Linux can be considered secure enough to be used in defense applications. Much of the usual FUD is present in the remarks, although an interesting question is raised regarding what defense and other government contractors are required to do in testing code (in this case anyway): is the closed code here being held to a higher standard than its open-source equivalent, and does this change the 'security through obscurity' argument?"
