Spoofing
Description
The adversary forges inputs that subsystems treat as trustworthy truth, time tags, sensor measurements, bus messages, or navigation signals, so onboard logic acts on fabricated reality. Because many control loops and autonomy rules assume data authenticity once it passes basic sanity checks, carefully shaped spoofs can trigger mode transitions, safing, actuator commands, or payload behaviors without touching flight code. Spoofing may occur over RF (e.g., GNSS, crosslinks, TT&C beacons), over internal networks/buses (message injection with valid identifiers), or at sensor/actuator interfaces (electrical/optical stimulation that produces plausible readings). Effects range from subtle bias (drifting estimates, skewed calibrations) to acute events (unexpected slews, power reconfiguration, recorder re-indexing), and can also pollute downlinked telemetry or science products so ground controllers interpret a false narrative. The hallmark is that the spacecraft chooses the adversary’s action path because the forged data passes through normal processing chains.

EU regulation articles
Authentication obligations bind inputs to verifiable identities; spoofed inputs lacking valid authentication tokens are rejected by subsystems applying these procedures.
Integrity protection on inputs (sensor measurements, time tags, bus messages) resists fabricated content being treated as authoritative truth.
Spoofing attacks input authenticity; 85(1)'s cryptographic concept defines the authentication mechanisms (TT&C MACs, crosslink auth, sensor source verification) that defeat spoofed inputs.
Spoofing parent (primary: Art. 85(1)/(3)) cascades to 85(2) — key lifecycle includes counter discipline against spoofed-input acceptance.
85(3)(a)'s end-to-end authentication between satellite control centres and space segment is the cryptographic posture that defeats RF-layer spoofing.
Spoofed-input artefacts (estimator drift, unscheduled mode transitions, off-axis actuator commands) are detectable through cross-source-fusion and behavioural-anomaly monitoring the entity's incident-handling capability under Art. 21(2)(b) must operate.
Art. 21(2)(h) is an organisational cryptography-policy obligation and does not reach the external GNSS/PNT signal spoofing that dominates this technique, which is interdicted at the signal layer (GNSS signal authentication such as Galileo OSNMA/PRS), not by the operator's crypto policy. It relates to the entity's cryptographic posture but neither mitigates nor governs signal spoofing.
Secure-authentication procedures bind inputs to verifiable identities; spoofed inputs that lack the required authentication tags or counters are rejected by subsystems applying these procedures.
Monitoring-and-logging procedures must surface inputs that violate authenticator expectations, time/sequence consistency or sensor-fusion bounds — the observable signatures of spoofing.
ENISA controls
On-board message encryption is relevant to spacecraft-bus message protection, but the confidentiality excerpt does not provide the authenticity checks needed to actively counter spoofed bus inputs.
Real-time physics-model verification of data inputs to bus and payload is the named defense against forged readings producing implausible state.
Authentication of users, devices, and assets — including bus-level authentication — ensures forged inputs cannot pass through normal processing chains.
Cross-reference controls
Supported by two independent derivations that agree, neither of them SafeMode's invention. Through NIST 800-53: SafeMode's curated mapping records EX-0014 against IA-3 Device Identification and Authentication, and CSF 2.0's own crosswalk names that control as an informative reference for PR.AA-03. Through SPARTA: SPARTA's catalog maps EX-0014 to countermeasure CM0031 Authentication, and that countermeasure's own CSF references include PR.AA-03. Recorded as `addresses` rather than `mitigates` because a CSF subcategory states an outcome to be achieved while the underlying control states the mechanism that achieves it, which is the mechanism-versus-mandate ceiling in decisions entry 15.
Derived by composition, not from a source that names this pair. D3FEND publishes that Application Protocol Command Analysis counters T1565.002 Transmitted Data Manipulation; SafeMode's curated mapping records EX-0014 as addressing that same adversary behaviour in the space domain. Analysing application-protocol remote commands is directly the telecommand-validation problem: on-board command handlers and the ground command chain both inspect opcode, argument, and sequencing structure before acting. Recorded at moderate confidence because the supporting chain is two documented edges rather than one source attesting the pair directly.
Derived by composition, not from a source that names this pair. D3FEND publishes that Protocol Metadata Anomaly Detection counters T1565.002 Transmitted Data Manipulation; SafeMode's curated mapping records EX-0014 as addressing that same adversary behaviour in the space domain. Protocol metadata anomaly detection applies to the telecommand and telemetry link and to internal bus framing, both of which carry structured, baselineable metadata. Recorded at moderate confidence because the supporting chain is two documented edges rather than one source attesting the pair directly.
T1565.002 'Transmitted Data Manipulation' addresses adversary alteration of data in transit to influence outcomes; SPARTA EX-0014 'Spoofing' is the parent-level equivalent for spoofing signals/data sent to the spacecraft. Cross-tactic moderate (impact vs execution).
T1692 'Unauthorized Message' addresses adversary sending unauthorised messages to deceive control systems — SPARTA EX-0014 'Spoofing' parent covers spoofing signals/data sent to the spacecraft, which create unauthorised message-class entities. Cross-tactic moderate (evasion/impair vs execution).
The practice names spoofing, but its subject is the communications link, whereas the parent spoofing technique spans forged sensor measurements, internal bus messages, and navigation signals as well. The dominant scope sits outside the practice, so this is addresses rather than mitigates.

EX-0014 (parent Spoofing) is multi-modal data spoofing across bus, time, sensor, PNT, and ballistic paths (its sub-techniques EX-0014.01 through EX-0014.05). SC-23 session authenticity interdicts only the bus and session path; the sensor mode (data consumed below any session layer) and the GNSS mode (RF front-end signal spoofing) never pass through an authenticated session, so session authenticity covers a non-dominant slice of the parent's dominant scope. A parent cannot have tighter session-authenticity coverage than its most-session-oriented child EX-0014.02, which was itself downgraded, so the relationship is addresses.
