a. Test the contingency plan for the system [Assignment: organization-defined frequency] using the following tests to determine the effectiveness of the plan and the readiness to execute the plan: [Assignment: organization-defined tests]. b. Review the contingency plan test results; and c. Initiate corrective actions, if needed.

| CM0008 | Security Testing Results | As penetration testing and vulnerability scanning is a best practice, protecting the results from these tests and scans is equally important. These reports and results typically outline detailed vulnerabilities and how to exploit them. As with countermeasure CM0001, protecting sensitive information from disclosure to threat actors is imperative. | D3-AI D3-AVE | |

| SV-MA-2 |
Heaters and flow valves of the propulsion subsystem are controlled by electric signals so cyberattacks against these signals could cause propellant lines to freeze, lock valves, waste propellant or even put in de-orbit or unstable spinning |
|
| SV-AV-4 |
Attacking the scheduling table to affect tasking |
|
| SV-MA-3 |
Attacks on critical software subsystems Attitude Determination and Control (AD&C) subsystem determines and controls the orientation of the satellite. Any cyberattack that could disrupt some portion of the control loop - sensor data, computation of control commands, and receipt of the commands would impact operations Telemetry, Tracking and Commanding (TT&C) subsystem provides interface between satellite and ground system. 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. |

Malicious Use of hardware commands - backdoors / critical commands |

| SV-AV-2 |
Satellites base many operations on timing especially since many operations are automated. Cyberattack to disrupt timing/timers could affect the vehicle (Time Jamming / Time Spoofing) |
|
| SV-AV-3 |
Affect the watchdog timer onboard the satellite which could force satellite into some sort of recovery mode/protocol |
|
| SV-AV-5 |
Using fault management system against you. Understanding the fault response could be leveraged to get satellite in vulnerable state. Example, safe mode with crypto bypass, orbit correction maneuvers, affecting integrity of TLM to cause action from ground, or some sort of RPO to cause S/C to go into safe mode; |

| SV-IT-1 |
Communications system spoofing resulting in denial of service and loss of availability and data integrity |

Communications system jamming resulting in denial of service and loss of availability and data integrity |

| SV-MA-6 |
Not planning for security on SV or designing in security from the beginning |

Testing only focuses on functional requirements and rarely considers end to end or abuse cases |

| SPARTA ID | Requirement | Rationale/Additional Guidance/Notes |
|---|---|---|
| SPR-258 | The [organization] shall test the contingency plan, with special consideration for space operations, to determine the effectiveness of the plan and readiness to execute the plan.{SV-MA-5}{CP-4} | Contingency plans must be validated under realistic mission conditions. Testing confirms feasibility during communication latency or constrained power states. Exercises reveal gaps in readiness. Preparedness reduces recovery time during incidents. |

| REC-0008 | Gather Supply Chain Information | Threat actors map the end-to-end pathway by which hardware, software, data, and people move from design through AIT, launch, and on-orbit sustainment. They catalog manufacturers and lots, test and calibration houses, logistics routes and waypoints, integrator touchpoints, key certificates and tooling, update and key-loading procedures, and who holds custody at each handoff. They correlate this with procurement artifacts, SBOMs, BOMs, and service contracts to locate where trust is assumed rather than verified. Particular attention falls on exceptions, engineering builds, rework tickets, advance replacements, depot repairs, and urgent field updates, because controls are frequently relaxed there. The result is a prioritized list of choke points (board fabrication, FPGA bitstream signing, image repositories, CI/CD runners, cloud artifact stores, freight forwarders) where compromise yields outsized effect. | |
| REC-0008.03 | Known Vulnerabilities | Adversaries correlate discovered component and software versions with public and private vulnerability sources to assemble a ready exploit catalog. Inputs include CPE/CVE mappings, vendor advisories, CWE-class weaknesses common to selected RTOS/middleware, FPGA IP core errata, cryptographic library issues, and hardware stepping errata that interact with thermal/power regimes. They mine leaked documents, demo code, bug trackers, and community forums; pivot from ground assets to flight by following shared libraries and tooling; and watch for lag between disclosure and patch deployment. Even when a vulnerability seems “ground-only,” it may expose build systems or update paths that ultimately control flight artifacts. | |
| EX-0009 | Exploit Code Flaws | The adversary executes actions on-board by abusing defects in software that runs on the vehicle, ranging from application logic in flight software to libraries, drivers, and supporting services. Outcomes range from arbitrary code execution and privilege escalation to silent logic manipulation (e.g., bypassing interlocks, suppressing alarms) that appears operationally plausible. The hallmark of this technique is that the attacker co-opts existing code paths, often rarely used ones, to run unintended behavior under nominal interfaces. 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-0009.03 | Known Vulnerability (COTS/FOSS) | Using knowledge of the software composition on-board, the adversary maps components and versions to publicly or privately known defects and then crafts inputs to trigger them. Typical targets include standard libraries (libc, STL), cryptographic and compression libraries, protocol stacks (CCSDS implementations, IP over space links, SpaceWire bridges), filesystems and parsers (FITS/CCSDS packetization, custom table formats), and vendor SDKs for radios, sensors, or payloads. Triggers arrive as well-formed but malicious packets, frames, or files whose edge-case fields exercise version-specific bugs, overflowing a parser, bypassing an authentication check, or causing a kernel/driver fault that reboots into a more permissive mode. Because these flaws are documented somewhere, exploitation emphasizes matching the exact build and build-time options used on the mission. | |
