Threat Object Type	Type of the threat object. For example: file_hash

Use security framework annotations in an ad-hoc risk entry

Use annotations to add context from industry-standard mappings to your ad-hoc risk entry results. Only MITRE ATT&CK definitions are pre-populated for enrichment.

Annotations
Annotations are enriched with industry-standard context.

1. Scroll to Annotations.
2. Add annotations for the common framework names listed. These fields are for use with industry-standard mappings, but also allow custom values. Industry-standard mappings include values such as the following:

   Security Framework	Five Random Mapping Examples
   CIS 20	CIS 3, CIS 9, CIS 11, CIS 7, CIS 12
   Kill Chain	Reconnaissance, Actions on Objectives, Exploitation, Delivery, Lateral Movement
   MITRE ATT&CK	T1015, T1138, T1084, T1068, T1085 This field also contains mitre technique names for you to select because they are pre-populated for enrichment.
   NIST	PR.IP, PR.PT, PR.AC, PR.DS, DE.AE

3. Click Save.

Dashboard example
Consider MITRE ATT&CK annotations as an example. You see them in dashboards by ID, such as T1015, rather than by the technique name.

Unmanaged Annotations
Unmanaged annotations are not enriched with any industry-standard context.

1. Scroll to Unmanaged Annotations.
2. Click + Framework to add your own framework names and their mapping categories. These are free-form fields.
3. Click Save.

Search example
Consider unmanaged annotations as an example. If you search the risk index directly, you see your unmanaged annotations.

index=risk

Search results
Unmanaged annotations display results as annotations._all with your <unmanaged_attribute_value>, and annotations._frameworks with your <unmanaged_framework_value>.
