High-Level Requirements

The Program shall ensure all mission critical elements (hardware and software) comply with high levels of assurance for confidentiality, integrity, and availability to meet mission objectives.

Low-Level Requirements

Requirement Rationale/Additional Guidance/Notes
The spacecraft shall have on-board intrusion detection/prevention system that monitors the mission critical components or systems. {SV-AC-1,SV-AC-2,SV-MA-4} {SC-7} During SCRM, criticality analysis will aid in determining supply chain risk. For mission critical functions/components, extra scrutiny must be applied to ensure supply chain is secured.
The Program shall conduct a criticality analysis to identify mission critical functions and critical components and reduce the vulnerability of such functions and components through secure system design. {SV-SP-3,SV-SP-4,SV-AV-7,SV-MA-4} {SR-1,RA-9,SA-15(3),CP-2(8)}
The Program shall use all-source intelligence analysis on threats to mission critical capabilities and/or system components to inform risk management decisions. {SV-MA-4} {RA-3(2)} Risk assessment is an iterative process. The first assessment occurs early in the process to assess the base design, select mitigating and program specific controls. Assessments continue as the design development continues in order to assess and mitigate new risks and/or threats. This continues throughout the lifecycle because new risks/threats can develop from new vulnerabilities.
The Program shall conduct an assessment of risk, including the likelihood and magnitude of harm, from the unauthorized access, use, disclosure, disruption, modification, or destruction of the spacecraft and the information it processes, stores, or transmits. {SV-MA-4} {RA-3}
The Program's risk assessment shall include the full end to end communication pathway from the ground to the spacecraft. {SV-MA-4} {RA-3}
The Program shall document risk assessment results in [risk assessment report]. {SV-MA-4} {RA-3}
The Program shall review risk assessment results [At least annually if not otherwise defined in formal organizational policy]. {SV-MA-4} {RA-3}
The Program shall update the risk assessment [At least annually if not otherwise defined in formal institutional policy] or whenever there are significant changes to the information system or environment of operation (including the identification of new threats and vulnerabilities), or other conditions that may impact the security state of the spacecraft. {SV-MA-4} {RA-3} Not all defects (i.e., buffer overflows, race conditions, and memory leaks) can be discovered statically and require execution of the system. This is where space-centric cyber testbeds (i.e., cyber ranges) are imperative as they provide an environment to maliciously attack components in a controlled environment to discover these undesirable conditions. Technology has improved to where digital twins for spacecraft are achievable, which provides an avenue for cyber testing that was often not performed due to perceived risk to the flight hardware.
The Program shall coordinate penetration testing on [program-defined mission critical SV components (hardware and/or software)]. {SV-MA-4} {CA-8}

ID Name Description
REC-0001 Gather Spacecraft Design Information Threat actors may gather information about the victim SV's design that can be used for future campaigns or to help perpetuate other techniques. Information about the SV can include software, firmware, encryption type, purpose, as well as various makes and models of subsystems.
REC-0001.01 Software Threat actors may gather information about the victim SV's internal software that can be used for future campaigns or to help perpetuate other techniques. Information (e.g. source code, binaries, etc.) about commercial, open-source, or custom developed software may include a variety of details such as types, versions, and memory maps. Leveraging this information threat actors may target vendors of operating systems, flight software, or open-source communities to embed backdoors or for performing reverse engineering research to support offensive cyber operations.
REC-0001.02 Firmware Threat actors may gather information about the victim SV's firmware that can be used for future campaigns or to help perpetuate other techniques. Information about the firmware may include a variety of details such as type and versions on specific devices, which may be used to infer more information (ex. configuration, purpose, age/patch level, etc.). Leveraging this information threat actors may target firmware vendors to embed backdoors or for performing reverse engineering research to support offensive cyber operations.
REC-0001.03 Cryptographic Algorithms Threat actors may gather information about any cryptographic algorithms used on the victim SV's that can be used for future campaigns or to help perpetuate other techniques. Information about the algorithms can include type and private keys. Threat actors may also obtain the authentication scheme (i.e., key/password/counter values) and leverage it to establish communications for commanding the target SV or any of its subsystems. Some SVs only require authentication vice authentication and encryption, therefore once obtained, threat actors may use any number of means to command the spacecraft without needing to go through a legitimate channel. The authentication information may be obtained through reconnaissance of the ground system or retrieved from the victim SV.
REC-0001.04 Data Bus Threat actors may gather information about the data bus used within the victim SV that can be used for future campaigns or to help perpetuate other techniques. Information about the data bus can include the make and model which could lead to more information (ex. protocol, purpose, controller, etc.), as well as locations/addresses of major subsystems residing on the bus. Threat actors may also gather information about the bus voltages of the victim SV. This information can include optimal power levels, connectors, range, and transfer rate.
