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

|CM0002||COMSEC||A component of cybersecurity to deny unauthorized persons information derived from telecommunications and to ensure the authenticity of such telecommunications. COMSEC includes cryptographic security, transmission security, emissions security, and physical security of COMSEC material. It is imperative to utilize 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 AC-17(1) AC-17(10) AC-17(10) AC-17(2) AC-18 AC-18(1) AC-2(11) AC-3(10) CA-3 IA-4(9) IA-5 IA-5(7) IA-7 PL-8 PL-8(1) 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(10) SC-7(11) SC-7(18) SC-7(5) SC-8(1) SC-8(3) SI-10 SI-10(3) SI-10(5) SI-10(6) SI-19(4) SI-3(8)||D3-ET D3-MH D3-MAN D3-MENCR D3-NTF D3-ITF D3-OTF D3-CH D3-DTP D3-NTA D3-CAA D3-DNSTA D3-IPCTA D3-NTCD D3-RTSD D3-PHDURA D3-PMAD D3-CSPP D3-MA D3-SMRA D3-SRA||A.5.14 A.6.7 A.8.1 A.8.16 A.5.14 A.8.1 A.8.20 A.5.14 A.8.21 A.5.16 A.5.17 A.5.8 A.5.14 A.8.16 A.8.20 A.8.22 A.8.23 A.8.26 A.8.12 A.5.33 A.8.20 A.8.24 A.8.24 A.8.26 A.5.31 A.5.33 A.8.11|
|CM0073||Traffic Flow Analysis Defense||Utilizing techniques to assure traffic flow security and confidentiality to mitigate or defeat traffic analysis attacks or reduce the value of any indicators or adversary inferences. This may be a subset of COMSEC protections, but the techniques would be applied where required to links that carry TT&C and/or data transmissions (to include on-board the spacecraft) where applicable given value and attacker capability. Techniques may include but are not limited to methods to pad or otherwise obfuscate traffic volumes/duration and/or periodicity, concealment of routing information and/or endpoints, or methods to frustrate statistical analysis.||SC-8 SI-4(15)||D3-NTA D3-ANAA D3-RPA D3-NTCD||A.5.10 A.5.14 A.8.20 A.8.26|
|CM0036||Session Termination||Terminate the connection associated with a communications session at the end of the session or after an acceptable amount of inactivity which is established via the concept of operations.||AC-12 SC-10 SI-14(3)||D3-SDA||A.8.20|
|CM0072||Protocol Update / Refactoring||A protocol is a set of rules (i.e., formats and procedures) to implement and control some type of association (e.g., communication) between systems. Protocols can have vulnerabilities within their specification and may require updating or refactoring based on vulnerabilities or emerging threats (i.e., quantum computing).||CM-3 CP-11 SI-2||D3-NM D3-NVA D3-AI D3-AVE D3-SYSM D3-SYSVA D3-OAM D3-ORA D3-PMAD||8.1 9.3.3 A.8.9 A.8.32 A.5.29 A.6.8 A.8.8 A.8.32|
|CM0029||TRANSEC||Utilize TRANSEC in order to prevent interception, disruption of reception, communications deception, and/or derivation of intelligence by analysis of transmission characteristics such as signal parameters or message externals. For example, jam-resistant waveforms can be utilized to improve the resistance of radio frequency signals to jamming and spoofing. Note: TRANSEC is that field of COMSEC which deals with the security of communication transmissions, rather than that of the information being communicated.||AC-17 AC-18 AC-18(5) CA-3 CP-8 PL-8 PL-8(1) SC-16 SC-40 SC-40(1) SC-40(3) SC-40(4) SC-5 SC-8(1) SC-8(3) SC-8(4)||D3-MH D3-MAN D3-MENCR D3-NTA D3-DNSTA D3-ISVA D3-NTCD D3-RTA D3-PMAD D3-FC D3-CSPP D3-ANAA D3-RPA D3-IPCTA D3-NTCD D3-NTPM D3-TAAN||A.5.14 A.6.7 A.8.1 A.5.14 A.8.1 A.8.20 A.5.14 A.8.21 A.5.29 A.7.11 A.5.8 A.5.33|
