Threat actors may manipulate software dependencies (i.e. dependency confusion) and/or development tools prior to the customer receiving them in order to achieve data or system compromise. Software binaries and applications often depend on external software to function properly. spacecraft developers may use open source projects to help with their creation. These open source projects may be targeted by threat actors as a way to add malicious code to the victim spacecraft's dependencies.

|CM0001||Protect Sensitive Information||Organizations should look to identify and properly classify mission sensitive design/operations information (e.g., fault management approach) and apply access control accordingly. Any location (ground system, contractor networks, etc.) storing design information needs to ensure design info is protected from exposure, exfiltration, etc. Space system sensitive information may be classified as Controlled Unclassified Information (CUI) or Company Proprietary. Space system sensitive information can typically include a wide range of candidate material: the functional and performance specifications, any ICDs (like radio frequency, ground-to-space, etc.), command and telemetry databases, scripts, simulation and rehearsal results/reports, descriptions of uplink protection including any disabling/bypass features, failure/anomaly resolution, and any other sensitive information related to architecture, software, and flight/ground /mission operations. This could all need protection at the appropriate level (e.g., unclassified, CUI, proprietary, classified, etc.) to mitigate levels of cyber intrusions that may be conducted against the project’s networks. Stand-alone systems and/or separate database encryption may be needed with controlled access and on-going Configuration Management to ensure changes in command procedures and critical database areas are tracked, controlled, and fully tested to avoid loss of science or the entire mission. Sensitive documentation should only be accessed by personnel with defined roles and a need to know. Well established access controls (roles, encryption at rest and transit, etc.) and data loss prevention (DLP) technology are key countermeasures. The DLP should be configured for the specific data types in question.||AC-3(11) AC-4(23) AC-4(25) AC-4(6) CA-3 CM-12 CM-12(1) PL-8 PL-8(1) PM-11 PM-17 SA-3 SA-3(1) SA-3(2) SA-4(12) SA-5 SA-8 SA-9(7) SC-16 SC-8(1) SC-8(3) SI-21 SI-23 SR-12 SR-7||D3-AI D3-AVE D3-NVA D3-CH D3-CBAN D3-CTS D3-PA D3-FAPA D3-SAOR||A.8.4 A.8.11 A.8.10 A.5.14 A.8.21 A.5.8 A.5.2 A.5.8 A.8.25 A.8.31 A.8.33 7.5.1 7.5.2 7.5.3 A.5.37 A.8.27 A.8.28 A.5.33 A.8.10 A.5.22|
|CM0010||Update Software||Perform regular software updates to mitigate exploitation risk. Software updates may need to be scheduled around operational down times. Release updated versions of the software/firmware systems incorporating security-relevant updates, after suitable regression testing, at a frequency no greater than mission-defined frequency [i.e., 30 days]. Ideally old versions of software are removed after upgrading but restoration states (i.e., gold images) are recommended to remain on the system.||CM-3(2) CM-3(7) CM-3(8) CM-4 CM-4(1) CM-7(4) SA-10(4) SA-11 SA-3 SA-8 SA-9 SI-2 SI-2(6)||D3-SU||A.8.9 A.8.9 A.8.9 A.8.31 A.8.19 A.5.2 A.5.8 A.8.25 A.8.31 A.8.27 A.8.28 A.5.2 A.5.4 A.5.8 A.5.14 A.5.22 A.5.23 A.8.21 A.8.29 A.8.30 A.6.8 A.8.8 A.8.32|
|CM0011||Vulnerability Scanning||Vulnerability scanning is used to identify known software vulnerabilities (excluding custom-developed software - ex: COTS and Open-Source). Utilize scanning tools to identify vulnerabilities in dependencies and outdated software (i.e., software composition analysis). Ensure that vulnerability scanning tools and techniques are employed that facilitate interoperability among tools and automate parts of the vulnerability management process by using standards for: (1) Enumerating platforms, custom software flaws, and improper configurations; (2) Formatting checklists and test procedures; and (3) Measuring vulnerability impact.||CM-10(1) RA-3 RA-5 RA-5(11) RA-5(3) SA-11 SA-15(7) SA-3 SA-4(5) SA-8 SI-3||D3-AI D3-NM D3-AVE D3-NVA D3-PM D3-FBA D3-OSM D3-SFA D3-PA D3-PSA D3-PLA D3-PCSV D3-FA D3-DA D3-ID D3-HD D3-UA||6.1.2 8.2 9.3.2 A.8.8 A.8.8 A.5.2 A.5.8 A.8.25 A.8.31 A.8.27 A.8.28 A.8.29 A.8.30 A.8.7|

|CM0013||Dependency Confusion||Ensure proper protections are in place for ensuring dependency confusion is mitigated like ensuring that internal dependencies be pulled from private repositories vice public repositories, ensuring that your CI/CD/development environment is secure as defined in CM0004 and validate dependency integrity by ensuring checksums match official packages.||CM-10(1) CM-11 CM-2 RA-5 SA-11 SA-3 SA-8 SA-8(9) SA-9||D3-LFP D3-UBA D3-RAPA D3-MAC||A.8.9 A.8.19 A.8.8 A.5.2 A.5.8 A.8.25 A.8.31 A.8.27 A.8.28 A.5.2 A.5.4 A.5.8 A.5.14 A.5.22 A.5.23 A.8.21 A.8.29 A.8.30|
