# Reference B: Exposure determination matrix

This appendix details how Cortex Cloud determines whether the organization is exposed to an attack. Exposure is evaluated within the viewing user's SBAC scope (see [Supply Chain Attacks](/application-security/software-supply-chain-security/supply-chain-attacks.md#sbac)).

| Signal present in environment                  | Contributes to "exposed / active" | Effect on sidecar                                                                                                                                                                             |
| ---------------------------------------------- | --------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Compromised package associated with the attack | Yes                               | Impacted assets show affected repositories/assets; attack is active                                                                                                                           |
| Compromised tool associated with the attack    | Yes                               | Impacted assets show affected pipelines; attack is active. A tool-only attack produces **no findings** (tools do not generate findings in this release) — exposure surfaces through pipelines |
| CVE associated with the attack                 | Yes                               | Impacted assets reflect the CVE footprint (findings, repositories, and images); attack is active                                                                                              |
| Open issue related to the attack               | Yes                               | Attack is active; issue is linked for remediation                                                                                                                                             |
| **None of the above**                          | No                                | Sidecar shows **no exposure detected** / no-longer-exposed; no affected assets                                                                                                                |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/application-security/software-supply-chain-security/supply-chain-attacks/referenecs/reference-b-exposure-determination-matrix.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
