Operational dependency mapping identifies and models the dependencies of the organization's activities on each other and on the organization's performers (people, systems, and services.) This may include modeling the higher- and lower-level activities of an organization forming a hierarchy, or layering, of the dependencies in an organization's activities.

| ID | Name | Description | |
|---|---|---|---|
| IA-0001 | Compromise Supply Chain | Threat actors may manipulate or compromise products or product delivery mechanisms before the customer receives them in order to achieve data or system compromise. | |
| IA-0001.03 | Hardware Supply Chain | Threat actors may manipulate hardware components in the victim spacecraft prior to the customer receiving them in order to achieve data or system compromise. The threat actor can insert backdoors and give them a high level of control over the system when they modify the hardware or firmware in the supply chain. This would include ASIC and FPGA devices as well. A spacecraft component can also be damaged if a specific HW component, built to fail after a specific period, or counterfeit with a low reliability, breaks out. | |
| IA-0002 | Compromise Software Defined Radio | Threat actors may target software defined radios due to their software nature to establish C2 channels. Since SDRs are programmable, when combined with supply chain or development environment attacks, SDRs provide a pathway to setup covert C2 channels for a threat actor. | |
| IA-0004 | Secondary/Backup Communication Channel | Threat actors may compromise alternative communication pathways which may not be as protected as the primary pathway. Depending on implementation the contingency communication pathways/solutions may lack the same level of security (i.e., physical security, encryption, authentication, etc.) which if forced to use could provide a threat actor an opportunity to launch attacks. Typically these would have to be coupled with other denial of service techniques on the primary pathway to force usage of secondary pathways. | |
| IA-0004.02 | Receiver | Threat actors may target the backup/secondary receiver on the space vehicle as a method to inject malicious communications into the mission. The secondary receivers may come from different supply chains than the primary which could have different level of security and weaknesses. Similar to the ground station, the communication through the secondary receiver could be forced or happening naturally. | |
| IA-0005 | Rendezvous & Proximity Operations | Threat actors may perform a space rendezvous which is a set of orbital maneuvers during which a spacecraft arrives at the same orbit and approach to a very close distance (e.g. within visual contact or close proximity) to a target spacecraft. | |
| IA-0005.02 | Docked Vehicle / OSAM | Threat actors may leverage docking vehicles to laterally move into a target spacecraft. If information is known on docking plans, a threat actor may target vehicles on the ground or in space to deploy malware to laterally move or execute malware on the target spacecraft via the docking interface. | |
| IA-0006 | Compromise Hosted Payload | Threat actors may compromise the target spacecraft hosted payload to initially access and/or persist within the system. Hosted payloads can usually be accessed from the ground via a specific command set. The command pathways can leverage the same ground infrastructure or some host payloads have their own ground infrastructure which can provide an access vector as well. Threat actors may be able to leverage the ability to command hosted payloads to upload files or modify memory addresses in order to compromise the system. Depending on the implementation, hosted payloads may provide some sort of lateral movement potential. | |
| IA-0007 | Compromise Ground System | Threat actors may initially compromise the ground system in order to access the target spacecraft. Once compromised, the threat actor can perform a multitude of initial access techniques, including replay, compromising FSW deployment, compromising encryption keys, and compromising authentication schemes. Threat actors may also perform further reconnaissance within the system to enumerate mission networks and gather information related to ground station logical topology, missions ran out of said ground station, birds that are in-band of targeted ground stations, and other mission system capabilities. | |
| IA-0007.01 | Compromise On-Orbit Update | Threat actors may manipulate and modify on-orbit updates before they are sent to the target spacecraft. This attack can be done in a number of ways, including manipulation of source code, manipulating environment variables, on-board table/memory values, or replacing compiled versions with a malicious one. | |
| IA-0007.02 | Malicious Commanding via Valid GS | Threat actors may compromise target owned ground systems components (e.g., front end processors, command and control software, etc.) that can be used for future campaigns or to perpetuate other techniques. These ground systems components have already been configured for communications to the victim spacecraft. By compromising this infrastructure, threat actors can stage, launch, and execute an operation. Threat actors may utilize these systems for various tasks, including Execution and Exfiltration. | |
| IA-0009 | Trusted Relationship | Access through trusted third-party relationship exploits an existing connection that has been approved for interconnection. Leveraging third party / approved interconnections to pivot into the target systems is a common technique for threat actors as these interconnections typically lack stringent access control due to the trusted status. | |
| IA-0009.02 | Vendor | Threat actors may target the trust between vendors and the target space vehicle. Missions often grant elevated access to vendors in order to allow them to manage internal systems as well as cloud-based environments. The vendor's access may be intended to be limited to the infrastructure being maintained but it may provide laterally movement into the target space vehicle. Attackers may leverage security weaknesses in the vendor environment to gain access to more critical mission resources or network locations. In the space vehicle context vendors may have direct commanding and updating capabilities outside of the primary communication channel. | |
| IA-0011 | Auxiliary Device Compromise | Threat actors may exploit the auxiliary/peripheral devices that get plugged into space vehicles. It is no longer atypical to see space vehicles, especially CubeSats, with Universal Serial Bus (USB) ports or other ports where auxiliary/peripheral devices can be plugged in. Threat actors can execute malicious code on the space vehicles by copying the malicious code to auxiliary/peripheral devices and taking advantage of logic on the space vehicle to execute code on these devices. This may occur through manual manipulation of the auxiliary/peripheral devices, modification of standard IT systems used to initially format/create the auxiliary/peripheral device, or modification to the auxiliary/peripheral devices' firmware itself. | |
| EX-0005 | Exploit Hardware/Firmware Corruption | Threat actors can target the underlying hardware and/or firmware using various TTPs that will be dependent on the specific hardware/firmware. Typically, software tools (e.g., antivirus, antimalware, intrusion detection) can protect a system from threat actors attempting to take advantage of those vulnerabilities to inject malicious code. However, there exist security gaps that cannot be closed by the above-mentioned software tools since they are not stationed on software applications, drivers or the operating system but rather on the hardware itself. Hardware components, like memory modules and caches, can be exploited under specific circumstances thus enabling backdoor access to potential threat actors. In addition to hardware, the firmware itself which often is thought to be software in its own right also provides an attack surface for threat actors. Firmware is programming that's written to a hardware device's non-volatile memory where the content is saved when a hardware device is turned off or loses its external power source. Firmware is written directly onto a piece of hardware during manufacturing and it is used to run on the device and can be thought of as the software that enables hardware to run. In the space vehicle context, firmware and field programmable gate array (FPGA)/application-specific integrated circuit (ASIC) logic/code is considered equivalent to firmware. | |
| EX-0005.01 | Design Flaws | Threat actors may target design features/flaws with the hardware design to their advantage to cause the desired impact. Threat actors may utilize the inherent design of the hardware (e.g. hardware timers, hardware interrupts, memory cells), which is intended to provide reliability, to their advantage to degrade other aspects like availability. Additionally, field programmable gate array (FPGA)/application-specific integrated circuit (ASIC) logic can be exploited just like software code can be exploited. There could be logic/design flaws embedded in the hardware (i.e., FPGA/ASIC) which may be exploitable by a threat actor. | |
| EX-0009 | Exploit Code Flaws | Threats actors may identify and exploit flaws or weaknesses within the software running on-board the target spacecraft. These attacks may be extremely targeted and tailored to specific coding errors introduced as a result of poor coding practices or they may target known issues in the commercial software components. | |
| EX-0009.02 | Operating System | Threat actors may exploit flaws in the operating system code, which controls the storage, memory management, provides resources to the FSW, and controls the bus. There has been a trend where some modern spacecraft are running Unix-based operating systems and establishing SSH connections for communications between the ground and spacecraft. Threat actors may seek to gain access to command line interfaces & shell environments in these instances. Additionally, most operating systems, including real-time operating systems, include API functionality for operator interaction. Threat actors may seek to exploit these or abuse a vulnerability/misconfiguration to maliciously execute code or commands. | |
| PER-0002 | Backdoor | Threat actors may find and target various backdoors, or inject their own, within the victim spacecraft in the hopes of maintaining their attack. | |
| PER-0002.01 | Hardware | Threat actors may find and target various hardware backdoors within the victim spacecraft in the hopes of maintaining their attack. Once in orbit, mitigating the risk of various hardware backdoors becomes increasingly difficult for ground controllers. By targeting these specific vulnerabilities, threat actors are more likely to remain persistent on the victim spacecraft and perpetuate further attacks. | |
| DE-0004 | Masquerading | Threat actors may gain access to a victim spacecraft by masquerading as an authorized entity. This can be done several ways, including through the manipulation of command headers, spoofing locations, or even leveraging Insider's access (i.e., Insider Threat) | |
| LM-0001 | Hosted Payload | Threat actors may use the hosted payload within the victim spacecraft in order to gain access to other subsystems. The hosted payload often has a need to gather and send data to the internal subsystems, depending on its purpose. Threat actors may be able to take advantage of this communication in order to laterally move to the other subsystems and have commands be processed. | |
| LM-0004 | Visiting Vehicle Interface(s) | Threat actors may move from one spacecraft to another through visiting vehicle interfaces. When a vehicle docks with a spacecraft, many programs are automatically triggered in order to ensure docking mechanisms are locked. This entails several data points and commands being sent to and from the spacecraft and the visiting vehicle. If a threat actor were to compromise a visiting vehicle, they could target these specific programs in order to send malicious commands to the victim spacecraft once docked. | |
| EXF-0006 | Modify Communications Configuration | Threat actors can manipulate communications equipment, modifying the existing software, hardware, or the transponder configuration to exfiltrate data via unintentional channels the mission has no control over. | |
| EXF-0006.01 | Software Defined Radio | Threat actors may target software defined radios due to their software nature to setup exfiltration channels. Since SDRs are programmable, when combined with supply chain or development environment attacks, SDRs provide a pathway to setup covert exfiltration channels for a threat actor. | |
| EXF-0006.02 | Transponder | Threat actors may change the transponder configuration to exfiltrate data via radio access to an attacker-controlled asset. | |

Computations occur within the RF portion of the TT&C subsystem, presenting cyberattack vector Command and Data Handling (C&DH) subsystem is the brains of the satellite. It interfaces with other subsystems, the payload, and the ground. It receives, validate, decodes, and sends commands to other subsystems, and it receives, processes, formats, and routes data for both the ground and onboard computer. C&DH has the most cyber content and is likely the biggest target for cyberattack. Electrical Power Subsystem (EPS) provides, stores, distributes, and controls power on the satellite. An attack on EPS could disrupt, damage, or destroy the satellite. |

|
| SV-AC-8 |

Once access to an SDR is gained, the attacker could alter what the SDR thinks is correct frequencies and settings to communicate with the ground. |
|
| SV-SP-7 |
Software can be broken down into three levels (operating system and drivers’ layer, data handling service layer, and the application layer). Highest impact on system is likely the embedded code at the BIOS, kernel/firmware level. Attacking the on-board operating systems. Since it manages all the programs and applications on the computer, it has a critical role in the overall security of the system. Since threats may occur deliberately or due to human error, malicious programs or persons, or existing system vulnerability mitigations must be deployed to protect the OS. |
|

The TT&C is the lead contributor to satellite failure over the first 10 years on-orbit, around 20% of the time. The failures due to gyro are around 12% between year one and 6 on-orbit and then ramp up starting around year six and overtake the contributions of the TT&C subsystem to satellite failure. Need to ensure equipment is not counterfeit and the supply chain is sound. |

Based on the results of the risk assessment, the Program may require the developer to implement protective measures or other processes to ensure the integrity of the ASIC. {SV-SP-5} {SR-1,SR-5} |
| The developer shall use a DMEA certified environment to develop, code and test executable software (firmware or bit-stream) that will be programmed into a one-time programmable FPGA or be programmed into non-volatile memory (NVRAM) that the FPGA executes. {SV-SP-5} {SR-1,SR-5} |
| For FPGA pre-silicon artifacts that are developed, coded, and tested by a developer that is NOT DMEA accredited Trusted, the contractor/developer shall be subjected to a development environment and pre-silicon artifacts risk assessment by the Program. The assessment shall use Aerospace security guidance and requirements in TOR-2019-00506 Vol. 2, and TOR-2019-02543 ASIC and FPGA Risk Assessment Process and Checklist. Based on the results of the risk assessment, the Program may require the developer to implement protective measures or other processes to ensure the integrity of the FPGA pre-silicon artifacts. {SV-SP-5} {SR-1,SR-5} |
| In the event we want to levy the Government Microelectronics Assessment for Trust (GOMAT) framework outright, to perform ASIC and FPGA threat/vulnerability risk assessment, the following requirements would apply: {SV-SP-5} {SR-1,SR-5} * The GOMAT framework shall be used to perform an initial risk assessment via Aerospace TOR-2019-02543 ASIC/FPGA Risk Assessment Process and Checklist. * The GOMAT framework shall be used to provide ASIC/FPGA lifecycle security guidance and requirements via Aerospace TOR-2019-00506 Volumes & 2 “ASIC and FPGA Lifecyle Security: Threats and Countermeasures”. * The GOMAT framework shall be used to perform development environment vulnerability assessment via Aerospace TOR-2019-02543 ASIC/FPGA Risk Assessment Process and Checklist. * The GOMAT framework shall be used to perform development environment vulnerability (DEV) assessment using the tailored DEV requirements from Aerospace TOR-2019-00506 Volume 2. * The GOMAT framework shall be used to perform hardware Trojan horse (HTH) detection independent verification and validation (IV&V). * The GOMAT framework shall be used to perform incremental and final risk assessments via Aerospace TOR-2019-02543 ASIC/FPGA Risk Assessment Process and Checklist. * The GOMAT framework shall be used to recommend mitigations, based on the findings of the risk assessments, to address identified security concerns and vulnerabilities. |
