Create an ad hoc risk entry in Splunk Enterprise Security

Creating an ad-hoc risk entry allows you to make a manual, one-time adjustment to an object's risk score. You can use it to add a positive or negative number to the risk score of an object.

  1. Select Security Intelligence > Risk Analysis.
  2. Click Create Ad-hoc Risk Entry.
  3. Complete the form.
  4. Click Save.
Risk Modifiers Description
Risk Score The number added to a Risk object. Can be a positive or negative integer.
Risk object Text field. Wildcard with an asterisk (*)
Risk object type Drop-down: select to filter by.


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 FrameworkFive Random Mapping Examples
    CIS 20CIS 3, CIS 9, CIS 11, CIS 7, CIS 12
    Kill Chain Reconnaissance, Actions on Objectives, Exploitation, Delivery, Lateral Movement
    MITRE ATT&CKT1015, T1138, T1084, T1068, T1085
    This field also contains mitre technique names for you to select because they are pre-populated for enrichment.
    NISTPR.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>.
