Digital System

A digital system is a group of interacting or interrelated digital artifacts that act according to a set of rules to form a unified whole. A digital system, surrounded and influenced by its environment, is described by its boundaries, structure and purpose and expressed in its functioning. Systems are the subjects of study of systems theory.

D3FEND Techniques

Name	Description
D3-SYSM	System mapping encompasses the techniques to identify the organization's systems, how they are configured and decomposed into subsystems and components, how they are dependent on one another, and where they are physically located.
D3-SYSVA	System vulnerability assessment relates all the vulnerabilities of a system's components in the context of their configuration and internal dependencies and can also include assessing risk emerging from the system's design as a whole, not just the sum of individual component vulnerabilities.

SPARTA Countermeasures

ID	Name	Description
CM0009	Threat Intelligence Program	A threat intelligence program helps an organization generate their own threat intelligence information and track trends to inform defensive priorities and mitigate risk. Leverage all-source intelligence services or commercial satellite imagery to identify and track adversary infrastructure development/acquisition. Countermeasures for this attack fall outside the scope of the mission in the majority of cases.
CM0022	Criticality Analysis	Conduct a criticality analysis to identify mission critical functions, critical components, and data flows and reduce the vulnerability of such functions and components through secure system design. Focus supply chain protection on the most critical components/functions. Leverage other countermeasures like segmentation and least privilege to protect the critical components.
CM0046	Long Duration Testing	Perform testing using hardware or simulation/emulation where the test executes over a long period of time (30+ days). This testing will attempt to flesh out race conditions or time-based attacks.
CM0051	Fault Injection Redundancy	To counter fault analysis attacks, it is recommended to use redundancy to catch injected faults. For certain critical functions that need protected against fault-based side channel attacks, it is recommended to deploy multiple implementations of the same function. Given an input, the spacecraft can process it using the various implementations and compare the outputs. A selection module could be incorporated to decide the valid output. Although sensor nodes have limited resources, critical regions usually comprise the crypto functions, which must be secured.
CM0072	Protocol Update / Refactoring	A protocol is a set of rules (i.e., formats and procedures) to implement and control some type of association (e.g., communication) between systems. Protocols can have vulnerabilities within their specification and may require updating or refactoring based on vulnerabilities or emerging threats (i.e., quantum computing).
