Command and Data Flow Manipulation - IMP-0011

Command and Data Flow Manipulation is the d deliberate alteration of the source, destination, path, delivery, availability, timing, sequence, or duplication of commands or data as they move within, to, or from a spacecraft. An adversary may inject an unauthorized command or alter a legitimate command before execution. The adversary may also prevent traffic from arriving, cause it to arrive at the wrong time or destination, or change its sequence. This mechanism applies to both external communications and internal spacecraft pathways. Passive observation alone does not qualify. Altering command or data content may also constitute Data Manipulation. Vector: Illustrative Application Collect: If the objective is Collect, an adversary could duplicate or redirect protected telemetry to an unauthorized destination. Pivot: If the objective is Pivot, an adversary could route activity through spacecraft communication paths to reach another connected asset or trust domain. Subvert: TIf the objective is Subvert, an adversary could delay or reorder commands and telemetry to disrupt operations and mislead defenders. Seize: If the objective is Seize, an adversary could suppress legitimate command traffic while forwarding unauthorized commands to assume control of mission functions. Disable: If the objective is Disable, an adversary could block command or data flows required for the spacecraft to conduct its intended mission or an essential mission function.
