A junior developer is informed about the impact of new malware on an Advanced RISC Machine (ARM) CPU, and the code must be fixed accordingly. Based on the debug, the malware is able to insert itself in another process memory location. Which of the following technologies can the developer enable on the ARM architecture to prevent this type of malware?
Correct Answer: A
ARM's "Execute Never" (XN) feature is the architecture's equivalent of a no-execute (NX) or Data Execution Prevention (DEP) bit. By marking all writable memory regions as non-executable, you block any injected code, such as that placed in another process's heap or stack, from ever running. This prevents the malware from inserting itself into memory and then executing its payload.
