The [organization] shall maintain documentation tracing the strategies, tools, and methods implemented to mitigate supply chain risk .{SV-SP-3,SV-SP-4,SV-AV-7}{PM-30,RA-3(1),SA-12(1),SR-5}
|
Examples include: (1) Transferring a portion of the risk to the developer or supplier through the use of contract language and incentives; (2) Using contract language that requires the implementation of SCRM throughout the system lifecycle in applicable contracts and other acquisition and assistance instruments (grants, cooperative agreements, Cooperative Research and Development Agreements (CRADAs), and other transactions). Within the DOD some examples include: (a) Language outlined in the Defense Acquisition Guidebook section 13.13. Contracting; (b) Language requiring the use of protected mechanisms to deliver elements and data about elements, processes, and delivery mechanisms; (c) Language that articulates that requirements flow down supply chain tiers to sub-prime suppliers. (3) Incentives for suppliers that: (a) Implement required security safeguards and SCRM best practices; (b) Promote transparency into their organizational processes and security practices; (c) Provide additional vetting of the processes and security practices of subordinate suppliers, critical information system components, and services; and (d) Implement contract to reduce SC risk down the contract stack. (4) Gaining insight into supplier security practices; (5) Using contract language and incentives to enable more robust risk management later in the lifecycle; (6) Using a centralized intermediary or “Blind Buy” approaches to acquire element(s) to hide actual usage locations from an untrustworthy supplier or adversary;

|
The [organization] shall protect against supply chain threats to the system, system components, or system services by employing security safeguards as defined by NIST SP 800-161 Rev.1.{SV-SP-3,SV-SP-4,SV-AV-7,SV-SP-11}{PM-30,RA-3(1),SA-8(9),SA-8(11),SA-12,SI-3,SR-1}
|
The chosen supply chain safeguards should demonstrably support a comprehensive, defense-in-breadth information security strategy. Safeguards should include protections for both hardware and software. Program should define their critical components (HW & SW) and identify the supply chain protections, approach/posture/process.
|
|
The [organization] shall employ [organization]-defined techniques to limit harm from potential adversaries identifying and targeting the Program supply chain.{SV-SP-3,SV-SP-4,SV-AV-7,SV-SP-11}{SR-3(2),SC-38}
|
Examples of security safeguards that the organization should consider implementing to limit the harm from potential adversaries targeting the organizational supply chain, are: (1) Using trusted physical delivery mechanisms that do not permit access to the element during delivery (ship via a protected carrier, use cleared/official couriers, or a diplomatic pouch); (2) Using trusted electronic delivery of products and services (require downloading from approved, verification-enhanced sites); (3) Avoiding the purchase of custom configurations, where feasible; (4) Using procurement carve outs (i.e., exclusions to commitments or obligations), where feasible; (5) Using defensive design approaches; (6) Employing system OPSEC principles; (7) Employing a diverse set of suppliers; (8) Employing approved vendor lists with standing reputations in industry; (9) Using a centralized intermediary and “Blind Buy” approaches to acquire element(s) to hide actual usage locations from an untrustworthy supplier or adversary Employing inventory management policies and processes; (10) Using flexible agreements during each acquisition and procurement phase so that it is possible to meet emerging needs or requirements to address supply chain risk without requiring complete revision or re-competition of an acquisition or procurement; (11) Using international, national, commercial or government standards to increase potential supply base; (12) Limiting the disclosure of information that can become publicly available; and (13) Minimizing the time between purchase decisions and required delivery.

|
|
The [organization] (and Prime Contractor) shall conduct a supplier review prior to entering into a contractual agreement with a contractor (or sub-contractor) to acquire systems, system components, or system services.{SV-SP-3,SV-SP-4,SV-AV-7,SV-SP-11}{SR-6}
|
|
|
The [organization] shall employ [Selection (one or more): independent third-party analysis, Program penetration testing, independent third-party penetration testing] of [Program-defined supply chain elements, processes, and actors] associated with the system, system components, or system services.{SV-SP-3,SV-SP-4,SV-AV-7,SV-SP-11}{SR-6(1)}

The [organization] shall employ [Program-defined Operations Security (OPSEC) safeguards] to protect supply chain-related information for the system, system components, or system services.{SV-SP-3,SV-SP-4,SV-AV-7,SV-SP-11}{SR-7,SC-38,CP-2(8)}
|
OPSEC safeguards may include: (1) Limiting the disclosure of information needed to design, develop, test, produce, deliver, and support the element for example, supplier identities, supplier processes, potential suppliers, security requirements, design specifications, testing and evaluation result, and system/component configurations, including the use of direct shipping, blind buys, etc.; (2) Extending supply chain awareness, education, and training for suppliers, intermediate users, and end users; (3) Extending the range of OPSEC tactics, techniques, and procedures to potential suppliers, contracted suppliers, or sub-prime contractor tier of suppliers; and (4) Using centralized support and maintenance services to minimize direct interactions between end users and original suppliers.

|
* Identifying the class (e.g., exfiltration, Trojans, etc.), nature, or effect of cyberattack (e.g., exfiltration, subverted control, or mission interruption) is necessary to determine the type of response. The first order of identification may be to determine whether the event is an attack or a non-threat event (anomaly). The objective requirement would be to predict the impact of the detected signature.
* Unexpected conditions can include RF lockups, loss of lock, failure to acquire an expected contact and unexpected reports of acquisition, unusual AGC and ACS control excursions, unforeseen actuator enabling's or actions, thermal stresses, power aberrations, failure to authenticate, software or counter resets, etc. Mitigation might include additional TMONs, more detailed AGC and PLL thresholds to alert operators, auto-capturing state snapshot images in memory when unexpected conditions occur, signal spectra measurements, and expanded default diagnostic telemetry modes to help in identifying and resolving anomalous conditions.

Cyber-safe mode is an operating mode of a spacecraft during which all nonessential systems are shut down and the spacecraft is placed in a known good state using validated software and configuration settings. Within cyber-safe mode authentication and encryption should still be enabled. The spacecraft should be capable of reconstituting firmware and SW functions to preattack levels to allow for the recovery of functional capabilities. This can be performed by self-healing, or the healing can be aided from the ground. However, the spacecraft needs to have the capability to replan, based on available equipment still available after a cyberattack. The goal is for the vehicle to resume full mission operations. If not possible, a reduced level of mission capability should be achieved.
