                'embedded network devices to weaken defenses and provide new '
                'capabilities for themselves.  On such devices, the operating '
                'systems are typically monolithic and most of the device '
                'functionality and capabilities are contained within a single '

                'To change the operating system, the adversary typically only '
                'needs to affect this one file, replacing or modifying it.  '
                'This can either be done live in memory during system runtime '
                'for immediate effect, or in storage to implement the change '
                'on the next boot of the network device.',
