Importing custom rules

The Behavioral Detection Engine supports importing custom detection rules in .json format. In the
Cylance
 console, you can import custom detection rules into custom rule groups from the
CylanceOPTICS
 > Behavioral Detection Engine > Custom Rules
 tab. You can also export legacy rule sets in .json format and import them.
Before you import a custom detection rule, create a custom rule group. The custom rule group that you created appears as a card on the
Custom Rules
 screen.
Use these steps to export the legacy rule sets from the
Cylance
 console, create a custom rule group, and then import the legacy rule sets to the custom rule group:
  1. Navigate to
    CylanceOPTICS
     > Configurations > Rules
    .
  2. Beside the rule that you want to export, click
    Export
     and save the .json file with the rule conditions.

     > Behavioral Detection Engine > Custom Rules
    .
  4. In the
    Custom Rule
     tab, click
    Add
     and then add a new custom rule group.
  5. Click the custom rule group, and then on the right side, click
    Add > Import custom rules
    , and specify the .json file.

    . After validation, click
    Add
     to complete the import.

  7. On the
    Behavioral Detection Engine
     screen,
    open the BDE policy > Detection And Response
     tab where you can enable alerts, observations, and automated responses for your custom rules. The custom rule group will appear as a new card at the bottom of the
    Detection And Response
     tab when editing a BDE policy, under the
    Custom rules
     section.
