Automatic Dependent Surveillance Broadcast is an aircraft surveillance method in which planes continuously transmit position data and receive data from nearby aircraft. It supports a more networked view of air traffic than traditional radar. Because it depends on digital transmission, it also introduces cybersecurity and data integrity concerns.
What Automatic Dependent Surveillance Broadcast Is
Automatic Dependent Surveillance Broadcast, or ADS-B, is a surveillance method that lets aircraft broadcast their position and related flight data to nearby aircraft and ground systems. It creates a more cooperative air picture than radar alone, but the broadcast nature of the signal means trust, authenticity, and availability all matter.
How ADS-B Works
ADS-B relies on avionics that determine an aircraft's own location and then transmit that information at regular intervals. Nearby receivers, including other aircraft and air traffic infrastructure, can then use the broadcast to build situational awareness. Because the signal is typically open and standardised, the system is efficient and scalable, but it also assumes the data being received is accurate and timely.
Why ADS-B Matters for Airspace Awareness
Compared with purely ground-based surveillance, ADS-B supports wider visibility, faster updates, and better support for traffic coordination in equipped airspace. That makes it valuable for collision avoidance, flight monitoring, and operational efficiency. It also means that the integrity of the broadcast becomes part of safe airspace management, because aircraft and controllers may act on what the system reports.
When organisations depend on ADS-B data, they should treat the feed as a safety-relevant data source rather than a guaranteed source of truth. Any uncertainty in reception, spoofed data, or missing coverage can degrade the picture that pilots and systems rely on.
Cybersecurity and Data Integrity Implications
ADS-B is exposed to the core problem of open broadcast systems: an attacker or interference source does not need privileged access to influence what is seen. False position reports, signal pollution, jamming, and replay-style deception can all distort the surveillance picture. The result is not just bad data, but potentially unsafe operational decisions if the information is trusted without corroboration.
Organisations therefore need complementary surveillance sources, strong monitoring of anomalies, and clear rules for how ADS-B is validated against other inputs. The same principle applies to resilience, because even without a malicious actor, coverage gaps and receiver failures can leave blind spots.
Risk and Threat Considerations
ADS-B creates a real exposure because it is designed for broadcast convenience, not secrecy or strong built-in authentication. That makes spoofing, jamming, and data manipulation credible concerns wherever operators rely on ADS-B as a primary surveillance input.
Failure mechanism: An attacker or interference source can inject false aircraft data, suppress legitimate signals, or exploit receiver trust in unauthenticated broadcasts, causing inaccurate traffic pictures.
Impact: The resulting confusion can affect separation assurance, situational awareness, incident response, and confidence in downstream aviation systems that consume the feed.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST SP 800-53 Rev 5, NIST CSF 2.0, CIS Controls v8 and NIST AI RMF set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-53 Rev 5 | SI-4 — System Monitoring | ADS-B integrity depends on monitoring anomalous or spoofed surveillance data. |
| SC-8 — Transmission Confidentiality and Integrity | ADS-B is a broadcast transmission problem where integrity of communicated data matters. | |
| Recommendation — Monitor ADS-B feeds for anomalies, spoofing indicators, and coverage degradation. Apply integrity controls and validate broadcast data against independent surveillance sources. | ||
| NIST CSF 2.0 | DE.CM-01 — Monitoring for Unauthorized Personnel, Connections, Devices, and Software | ADS-B requires continuous monitoring for abnormal or unauthorised signal behaviour. |
| Recommendation — Continuously monitor surveillance inputs for abnormal transmissions and signal tampering. | ||
| CIS Controls v8 | CIS-13 — Network Monitoring and Defense | ADS-B security depends on detecting interference, spoofing, and anomalous traffic patterns. |
| Recommendation — Use network monitoring to detect anomalous broadcasts, interference, and spoofing patterns. | ||
| NIST AI RMF | Govern | ADS-B is a safety-relevant digital aviation capability that benefits from structured risk governance. |
| Recommendation — Govern ADS-B use by defining trust assumptions, oversight, and escalation for surveillance anomalies. | ||
Practitioner Guidance
What to watch for: Treat ADS-B as one layer in a wider surveillance stack, not as a standalone source of truth. Operators should look for inconsistent tracks, unexpected jumps in aircraft position, coverage gaps, and suspiciously repeated or implausible messages.
Governance implication: Security and aviation operations teams should define when ADS-B can be trusted on its own, when corroboration is required, and how anomalies are escalated. That decision is as much about operational safety as it is about cyber defence.
