Threat actors may capture the RF communications as it pertains to the downlink of the victim SV. This information can contain important telemetry such as onboard status and mission data.

| 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 | ||
