Marking definitions
The marking definitions object represents a specific marking.
Data markings represent restrictions, permissions, and other guidance for how data can be used and shared.
For example, data may be shared with the restriction that it must not be reshared, or that it must be encrypted at rest.
In STIX, data markings are specified using the marking definition object. These definitions are applied to STIX Objects using object markings and to individual properties of STIX Objects via granular markings.
