Data Manipulation: Runtime Data Manipulation

An attacker can use a controlled payload software or component to manipulate data of that or another component during the execution, if a MMU or a MPU is not implemented or is misconfigured. Only the most recent space qualified microprocessors (LEONII/III) have a MMU available, that provides only write protection. For secure spacecraft avionics, protection against read/write and execution access is necessary. The MMU or a MPU is extremely important if the payload is not trusted. [1] [2]
