Threat actors may capture signals and/or network communications as they travel on-board the vehicle (i.e., EMSEC/TEMPEST), via RF, or terrestrial networks. This information can be decoded to determine commanding and telemetry protocols, command times, and other information that could be used for future attacks.

| CM0002 | COMSEC | Utilizing secure communication protocols with strong cryptographic mechanisms to prevent unauthorized disclosure of, and detect changes to, information during transmission. Systems should also maintain the confidentiality and integrity of information during preparation for transmission and during reception. Spacecraft should not employ a mode of operations where cryptography on the TT&C link can be disabled (i.e., crypto-bypass mode). The cryptographic mechanisms should identify and reject wireless transmissions that are deliberate attempts to achieve imitative or manipulative communications deception based on signal parameters. | AC-17(1) AC-17(10) AC-17(10) AC-17(2) AC-18(1) AC-2(11) AC-3(10) IA-4(9) IA-5 IA-5(7) IA-7 SA-8(18) SA-9(6) SC-10 SC-12 SC-12(1) SC-12(2) SC-12(3) SC-12(6) SC-13 SC-16(3) SC-28(1) SC-28(3) SC-7 SC-7(11) SC-7(18) SI-10 SI-10(3) SI-10(5) SI-10(6) SI-19(4) | A.8.16 A.5.16 A.5.17 A.5.14 A.8.16 A.8.20 A.8.22 A.8.23 A.8.26 A.8.20 A.8.24 A.8.24 A.8.26 A.5.31 A.5.33 A.8.11 | ||
| CM0003 | TEMPEST | The spacecraft should protect system components, associated data communications, and communication buses in accordance with TEMPEST controls to prevent side channel / proximity attacks. Encompass the spacecraft critical components with a casing/shielding so as to prevent access to the individual critical components. | PE-19 PE-19(1) PE-21 | A.7.5 A.7.8 A.8.12 | ||
