Threat modelling AI applications
Data flows, trust boundaries and tools of an AI application are mapped to identify where untrusted inputs could manipulate the model or where data could leak.

Cybersecurity and cryptography protect AI sistem and the data they use. In this field the focus is threats specific to AI, such as prompt injection, poisoning and model theft, alongside conventional security of the software and infrastructure around models.
Cybersecurity and cryptography protect information sistem and data from unauthorised access, disruption and manipulation. They address threats that can spread rapidly across interconnected digital and physical systems. In artificial intelligence and data and compute, cybersecurity analysis identifies how a single compromise can propagate across sectors that share software, vendors or networks. It informs resilience requirements and cyber insurance. The canonical description is on STEM Commons.
Data flows, trust boundaries and tools of an AI application are mapped to identify where untrusted inputs could manipulate the model or where data could leak.
Provenance of datasets and model weights is recorded and verified with signatures and hashes before use.
Applications are tested with suites of injection attempts, and the success rate is tracked as defences change.

The model runs on the teaching values set by the controls. To calibrate it for a place, read it against these admitted layers and series, which this page’s map can draw:
Di seluruh enam pilar, dipimpin oleh Nexus Consortium
Controls are tested through red-team exercises, audits and formal analysis of cryptographic schemes. Incident data are used to check whether defences performed as intended.
| Pemeriksaan | Cara pelaksanaannya |
|---|---|
| Threat model review | Threat models are reviewed when the application or its tools change |
| Provenance verification | Model artefacts are checked against signed records |
| Regression testing | Security tests are rerun after each update |
Adversaries adapt, so historical data may not reflect future attacks. Software supply chains and legacy systems introduce weaknesses that are hard to inventory.
