Threat actors may intentionally degrade or manipulate the spacecraft’s onboard sensors or associated systems used for Space Domain Awareness (SDA). This allows an adversary to hide proximity operations, mislead threat detection logic, or disrupt autonomous responses by confusing local SDA feeds. Unlike debris field concealment, this technique targets the spacecraft's own perception systems through directed interference, spoofing, or environmental manipulation. There is a distinction with DE-0009.01 where threat actors could use debris or environment to hide themselves. Where with this sub-technique, the threat actor attacks your sensors so you can’t see them.

| CM0077 | Space Domain Awareness | The credibility and effectiveness of many other types of defenses are enabled or enhanced by the ability to quickly detect, characterize, and attribute attacks against space systems. Space domain awareness (SDA) includes identifying and tracking space objects, predicting where objects will be in the future, monitoring the space environment and space weather, and characterizing the capabilities of space objects and how they are being used. Exquisite SDA—information that is more timely, precise, and comprehensive than what is publicly available—can help distinguish between accidental and intentional actions in space. SDA systems include terrestrial-based optical, infrared, and radar systems as well as space-based sensors, such as the U.S. military’s Geosynchronous Space Situational Awareness Program (GSSAP) inspector satellites. Many nations have SDA systems with various levels of capability, and an increasing number of private companies (and amateur space trackers) are developing their own space surveillance systems, making the space environment more transparent to all users.* *https://csis-website-prod.s3.amazonaws.com/s3fs-public/publication/210225_Harrison_Defense_Space.pdf?N2KWelzCz3hE3AaUUptSGMprDtBlBSQG | CP-13 CP-2(3) CP-2(5) CP-2(7) PE-20 PE-6 PE-6(1) PE-6(2) PE-6(4) RA-6 SI-4(17) | D3-APLM D3-PM D3-HCI D3-SYSM | A.5.29 A.7.4 A.8.16 A.7.4 A.7.4 A.5.10 | |
| CM0079 | Maneuverability | Satellite maneuver is an operational tactic that can be used by satellites fitted with chemical thrusters to avoid kinetic and some directed energy ASAT weapons. For unguided projectiles, a satellite can be commanded to move out of their trajectory to avoid impact. If the threat is a guided projectile, like most direct-ascent ASAT and co-orbital ASAT weapons, maneuver becomes more difficult and is only likely to be effective if the satellite can move beyond the view of the onboard sensors on the guided warhead.* *https://csis-website-prod.s3.amazonaws.com/s3fs-public/publication/210225_Harrison_Defense_Space.pdf?N2KWelzCz3hE3AaUUptSGMprDtBlBSQG | CP-10(6) CP-13 CP-2 CP-2(1) CP-2(3) CP-2(5) PE-20 PE-21 | None | 7.5.1 7.5.2 7.5.3 A.5.2 A.5.29 A.8.1 A.5.30 A.5.29 A.5.10 | |
| CM0081 | Defensive Jamming and Spoofing | A jammer or spoofer can be used to disrupt sensors on an incoming kinetic ASAT weapon so that it cannot steer itself effectively in the terminal phase of flight. When used in conjunction with maneuver, this could allow a satellite to effectively “dodge” a kinetic attack. Similar systems could also be used to deceive SDA sensors by altering the reflected radar signal to change the location, velocity, and number of satellites detected, much like digital radio frequency memory (DRFM) jammers used on many military aircraft today. A spacebased jammer can also be used to disrupt an adversary’s ability to communicate.* *https://csis-website-prod.s3.amazonaws.com/s3fs-public/publication/210225_Harrison_Defense_Space.pdf?N2KWelzCz3hE3AaUUptSGMprDtBlBSQGate with an ASAT weapon. | CP-10(6) CP-13 CP-2 CP-2(1) CP-2(5) CP-2(7) PE-20 | D3-DO | 7.5.1 7.5.2 7.5.3 A.5.2 A.5.29 A.8.1 A.5.30 A.5.29 A.5.10 | |
| CM0086 | Filtering and Shuttering | Filters and shutters can be used on remote sensing satellites to protect sensors from laser dazzling and blinding. Filters can protect sensors by only allowing light of certain wavelengths to reach the sensors. Filters are not very effective against lasers operating at the same wavelengths of light the sensors are designed to detect because a filter that blocks these wavelengths would also block the sensor from its intended mission. A shutter acts by quickly blocking or diverting all light to a sensor once an anomaly is detected or a threshold is reached, which can limit damage but also temporarily interrupts the collection of data.* *https://csis-website-prod.s3.amazonaws.com/s3fs-public/publication/210225_Harrison_Defense_Space.pdf?N2KWelzCz3hE3AaUUptSGMprDtBlBSQG | CP-13 PE-18 SC-30(5) SC-5 SC-5(3) | D3-PH | A.5.29 A.5.10 A.7.5 A.7.8 | |
| CM0087 | Defensive Dazzling/Blinding | Laser systems can be used to dazzle or blind the optical or infrared sensors on an incoming ASAT weapon in the terminal phase of flight. This is similar to the laser infrared countermeasures used on aircraft to defeat heat-seeking missiles. Blinding an ASAT weapon’s guidance system and then maneuvering to a new position (if necessary) could allow a satellite to effectively “dodge” a kinetic attack. It could also be used to dazzle or blind the optical sensors on inspector satellites to prevent them from imaging a satellite that wants to keep its capabilities concealed or to frustrate adversary SDA efforts.* *https://csis-website-prod.s3.amazonaws.com/s3fs-public/publication/210225_Harrison_Defense_Space.pdf?N2KWelzCz3hE3AaUUptSGMprDtBlBSQG | CP-10(6) CP-13 CP-2 CP-2(1) CP-2(5) CP-2(7) PE-20 SC-30(5) | None | 7.5.1 7.5.2 7.5.3 A.5.2 A.5.29 A.8.1 A.5.30 A.5.29 A.5.10 | |
| CM0034 | Monitor Critical Telemetry Points | Monitor defined telemetry points for malicious activities (i.e., jamming attempts, commanding attempts (e.g., command modes, counters, etc.)). This would include valid/processed commands as well as commands that were rejected. Telemetry monitoring should synchronize with ground-based Defensive Cyber Operations (i.e., SIEM/auditing) to create a full space system situation awareness from a cybersecurity perspective. | AC-17(1) AU-3(1) CA-7(6) IR-4(14) PL-8 PL-8(1) SA-8(13) SC-16 SC-16(1) SC-7 SI-3(8) SI-4(7) | D3-NTA D3-PM D3-PMAD D3-RTSD | A.8.16 A.5.8 A.5.14 A.8.16 A.8.20 A.8.22 A.8.23 A.8.26 | |
| CM0032 | On-board Intrusion Detection & Prevention | Utilize on-board intrusion detection/prevention system that monitors the mission critical components or systems and audit/logs actions. The IDS/IPS should have the capability to respond to threats (initial access, execution, persistence, evasion, exfiltration, etc.) and it should address signature-based attacks along with dynamic never-before seen attacks using machine learning/adaptive technologies. The IDS/IPS must integrate with traditional fault management to provide a wholistic approach to faults on-board the spacecraft. Spacecraft should select and execute safe countermeasures against cyber-attacks.  These countermeasures are a ready supply of options to triage against the specific types of attack and mission priorities. Minimally, the response should ensure vehicle safety and continued operations. Ideally, the goal is to trap the threat, convince the threat that it is successful, and trace and track the attacker — with or without ground support. This would support successful attribution and evolving countermeasures to mitigate the threat in the future. “Safe countermeasures” are those that are compatible with the system’s fault management system to avoid unintended effects or fratricide on the system. | AU-14 AU-2 AU-3 AU-3(1) AU-4 AU-4(1) AU-5 AU-5(2) AU-5(5) AU-6(1) AU-6(4) AU-8 AU-9 AU-9(2) AU-9(3) CA-7(6) CM-11(3) CP-10 CP-10(4) IR-4 IR-4(11) IR-4(12) IR-4(14) IR-4(5) IR-5 IR-5(1) PL-8 PL-8(1) RA-10 RA-3(4) SA-8(21) SA-8(22) SA-8(23) SC-16(2) SC-32(1) SC-5 SC-5(3) SC-7(10) SC-7(9) SI-10(6) SI-16 SI-17 SI-3 SI-3(10) SI-3(8) SI-4 SI-4(1) SI-4(10) SI-4(11) SI-4(13) SI-4(16) SI-4(17) SI-4(2) SI-4(23) SI-4(24) SI-4(25) SI-4(4) SI-4(5) SI-4(7) SI-6 SI-7(17) SI-7(8) | D3-FA D3-DA D3-FCR D3-FH D3-ID D3-IRA D3-HD D3-IAA D3-FHRA D3-NTA D3-PMAD D3-RTSD D3-ANAA D3-CA D3-CSPP D3-ISVA D3-PM D3-SDM D3-SFA D3-SFV D3-SICA D3-USICA D3-FBA D3-FEMC D3-FV D3-OSM D3-PFV D3-EHB D3-IDA D3-MBT D3-SBV D3-PA D3-PSMD D3-PSA D3-SEA D3-SSC D3-SCA D3-FAPA D3-IBCA D3-PCSV D3-FCA D3-PLA D3-UBA D3-RAPA D3-SDA D3-UDTA D3-UGLPA D3-ANET D3-AZET D3-JFAPA D3-LAM D3-NI D3-RRID D3-NTF D3-ITF D3-OTF D3-EI D3-EAL D3-EDL D3-HBPI D3-IOPR D3-KBPI D3-MAC D3-SCF | A.8.15 A.8.15 A.8.6 A.8.17 A.5.33 A.8.15 A.8.15 A.5.29 A.5.25 A.5.26 A.5.27 A.5.8 A.5.7 A.8.12 A.8.7 A.8.16 A.8.16 A.8.16 A.8.16 | |
| CM0051 | Fault Injection Redundancy | To counter fault analysis attacks, it is recommended to use redundancy to catch injected faults. For certain critical functions that need protected against fault-based side channel attacks, it is recommended to deploy multiple implementations of the same function. Given an input, the spacecraft can process it using the various implementations and compare the outputs. A selection module could be incorporated to decide the valid output. Although sensor nodes have limited resources, critical regions usually comprise the crypto functions, which must be secured. | CP-4(5) PL-8 PL-8(1) SA-3 SA-8 SA-8(30) SI-13 SI-4(25) | D3-AH D3-SYSVA D3-ORA | A.5.8 A.5.2 A.5.8 A.8.25 A.8.31 A.8.27 A.8.28 | |
