APIs and scripts for validating STIX 2.x documents.
The STIX Validator checks that STIX JSON content conforms to the requirements specified in the STIX 2.1 specification. In addition to checking conformance with the JSON schemas, the validator checks conformance with requirements that cannot be specified in JSON schema, as well as with established “best practices.” This validator is non-normative; in cases of conflict with the STIX 2.1 specification, the specification takes precedence.
The STIX 2.1 specification contains two types of requirements: mandatory “MUST” requirements, and recommended “SHOULD” best practice requirements. The validator checks documents against the “MUST” requirements using JSON schemas. Some of these mandatory requirements cannot be implemented in JSON Schema, however, so the validator uses Python functions to check them. The “SHOULD” requirements are all checked by Python functions, and options may be used to ignore some or all of these recommended “best practices.”
The only exception to this is the mandatory requirement that an object’s ‘type’ be one of those defined by a STIX Object in the specification. This rules out custom objects, so this check was made optional.
The validator also color-codes its output to make it easier to tell at a glance whether validation passed.
The easiest way to install the STIX validator is with pip:
$ pip install stix2-validator
As A Script
The validator comes with a bundled script which you can use to validate a JSON file containing STIX content:
$ stix2_validator <stix_file.json>
As A Library
You can also use this library to integrate STIX validation into your own tools. You can validate a JSON file:
from stix2validator import validate_file, print_results results = validate_file("stix_file.json") print_results(results)
You can also validate a JSON string using validate_string(), or a Python dictionary representing a STIX object using validate_instance(). For more information, see the full documentation here.
