## K.1 Including security information in a SPDX document

SPDX 2.x has the concept of an External Reference for a Package to "reference an external source of additional information, metadata, enumerations, asset identifiers, or downloadable content believed to be relevant to the Package."
SPDX 2.x has the concept of an External Reference for a Package to "reference an external source of additional information, metadata, enumerations, asset identifiers, or downloadable content believed to be relevant to the Package."

The specification for External Reference identifiers (Annex F) has four defined categories:
- Security: CPE, SWID tag identifier, or reference to security information

- Security: CPE, SWID tag identifier, or reference to security information
- Package-Manager: package identifier and locator
- Persistent-id: identifier which is guaranteed to remain stable (persistent) over time
- Persistent-id: identifier which is guaranteed to remain stable (persistent) over time
- Other: Use if none of the above match your use case

This section provides usage scenarios of how to leverage the Security and Persistent-id category external references specified above to refer to external security information. A complete SPDX document using these can be found in the examples directory within the SPDX code repository. Multiple instances and types of external security information may be included within a SPDX document.

Note that identifiers (e.g. CPE, GitBOM, SWID) are spread throughout Annex F and sometimes locators refer to identifiers.

### K.1.1 Linking to an advisory

Including a reference to a Common Vulnerabilities and Exposures (CVE) advisory applicable to a package is shown in the example below. A SPDX creator should include current publicly known vulnerabilities at the time of document creation. SPDX consumers should always assume vulnerabilities enumerated by a SPDX creator to be out-of-date.

Providing a link to such data at the time the SBOM is published provides a pointer for where to find this relevant vulnerability information without promulgating vulnerability information inside the SBOM. This is advantageous because the vulnerability information has a short shelf-life (it will change frequently) while the SBOM component data isn’t likely to change if the software has not changed.
