How does adaptive partitioning help with security?
QNX adaptive partitioning technology is a great security tool because it allows the system designer to isolate parts of the system from each other. Adaptive partitioning, for example, can be used to guarantee CPU time to a maintenance process that allows remote login. If, for example, the system is under a denial-of-service attack and all of the CPU is being used to lock out other processes, the maintenance process can still run within its partition while the rest of the system is restarted or repaired. Adaptive partitioning can similarly be used to isolate untrusted parts of the system CPU resources are allocated such that the partition with the untrusted content can never use more than the budgeted resources.
