   Whenever you create new object records for observables, indicators, entities or objects a source record is created and a prompt message is displayed that the new object record is created and then the user is redirected to the aggregated record.
5. On the form, fill in the fields.

   表 : 1. Choose Entity&Value

   Entity	Select the entity object sighting record. 注: During any new object sighting record creation, an associated relationship record is required for aggregation.
   Sighting of	Indicates the that a particular entity or indicator was observed in an environment which can be an indication to a potential threat. 注: Select the sighting related record which is associated to the object selected in the Entity field so that related records can now be created and aggregate the sighting records.

   表 : 2. Object Sighting Details view

   Field	Description
   ID	Unique ID for a course of action to prevent an attack.
   Description	A description that provides more details and context about the Sighting.
   First Seen	The beginning of the time window during which the SDO referenced by which the property was sighted.
   Last Seen	The end of the time window during which the SDO referenced by which the property was sighted.
   Count	If present, this must be an integer between 0 and 999,999,999 inclusive and represents the number of times the SDO referenced by which the property was sighted.
   Is Summary	Indicates whether the Sighting should be considered the summary data. Summary data is an aggregation of previous Sightings reports and should not be considered primary source data.
   Is Internal	Indicates whether the Sighting is internal.
   TLP	TLP is used to ensure that sensitive information is shared with the appropriate audience. It employs four colors (White, Green, Amber, and Red) to indicate different degrees of sensitivity.
   Confidence	Enter the confidence for this course of action.
   Source	Specifies the threat source from which this object record is created.
   Revoked	Indicates that the revoked objects are no longer considered valid by the object creator.

   表 : 3. Insights

   Field	Description
   Notes	Add any additional notes for this intrusion set.

   表 : 4. Additional Information

   Field	Description
   Additional Context	Add any additional context for this attack pattern.
   Spec Version	The version of the STIX specification used to represent this object. The value of this property must be 2.1 for STIX Objects defined according to this specification.
   Lang	This property identifies the language of the text content in this object.
   Created Time In Source	Specifies the time the object is created in the source.
   Extensions	Indicates the extensions of attack pattern.
   Modified Time in Source	Specifies the time the object is modified in the source.
   Processing Status	Represents the processing status of this object, course of action.

6. Click Save.
   After you save, a prompt message is displayed indicating that A new observable record is created. Click Continue to edit the record and create new relationships.
7. Click Continue.
   重要:

   After you create a new observable record, Prevent System Updates check box is displayed.

   Select this check box to prevent any updates from the system after the observable or indicator or STIX objects records are created.

表 : 6. Related Records

Field	Description
External References	Lists the external references which refer to non-STIX information. This property is used to provide one or more external object identifiers.
Objects	Lists the objects associated with the sightings.
Indicators	Lists the related Indicators of Compromise (IoC) that have been identified by the threat source associated with this object.

1. You can link and unlink the related records associated with this object. For more information, see Link Threat Intel Related Records.
2. The various SDOs within the TI library also contains the potential relationships. To establish a relationships between any two objects, you use the Potential Relationships link from the Threat Intel Library to confirm the relationships between the objects. For more information, see Confirm object-object potential relationships.
3. Also, use the Related Records section from the objects form view to confirm the relationships between two Objects using the Potential Relationships section available on the form view. For more information on see, Confirm Potential Relationships from Related Records.
4. You can add objects to cases. For more information, see Add to Case.
