STIXTypeSTIX Core Schema

STIXType defines a bundle of information characterized in the Structured Threat Information eXpression (STIX) language.


Suggested Practices

As of STIX 1.2, the contextual fields in STIX_Header have been deprecated. If you want to give context to set of STIX content you should use a Report. The Information_Source field is still available and should be used to indicate the source of content that’s included in the report (in other words, it’s equivalent to setting the Information_Source in each individual construct).


Fields

Field Name Type Description
@idoptional QName

Specifies a globally unique identifier for this STIX Package.

@idrefoptional QName

Specifies a globally unique identifier of a STIX Package specified elsewhere.

When idref is specified, the id attribute must not be specified, and any instance of this STIX Package should not hold content.

DEPRECATED: This field is deprecated and will be removed in the next major version of STIX. Its use is strongly discouraged except for legacy applications.

@timestampoptional dateTime

Specifies a timestamp for the definition of a specific version of a STIX Package. When used in conjunction with the id, this field is specifying the definition time for the specific version of the STIX Package. When used in conjunction with the idref, this field is specifying a reference to a specific version of a STIX Package defined elsewhere. This field has no defined semantic meaning if used in the absence of either the id or idref fields.

DEPRECATED: This field is deprecated and will be removed in the next major version of STIX. Its use is strongly discouraged except for legacy applications.

@versionoptional STIXPackageVersionEnum

Specifies the relevant STIX schema version for this content.

Observables0..1 ObservablesType

Characterizes one or more cyber observables.

DEPRECATION NOTICE: The use of the @idref attribute on observables at the top level of this list is deprecated and will be removed in the next major version of STIX. Its use is strongly discouraged except for legacy applications. Observables in this list should only be embedded, not referenced.

TTPs0..1 TTPsType

Characterizes one or more cyber threat adversary Tactics, Techniques or Procedures.

DEPRECATION NOTICE: The use of the @idref attribute on TTPs at the top level of this list is deprecated and will be removed in the next major version of STIX. Its use is strongly discouraged except for legacy applications. TTPs in this list should only be embedded, not referenced.

Exploit_Targets0..1 ExploitTargetsType

Characterizes one or more potential targets for exploitation.

DEPRECATION NOTICE: The use of the @idref attribute on exploit targets at the top level of this list is deprecated and will be removed in the next major version of STIX.
