Score Calculation

In order to normalize the score fetched from the Security Advisor into a 1-1000 range, perform the following steps:

  1. 1-900 score is first converted to the range of 0 to 1 using this formula:
    score = (behavior_score - minvalue) / (maxvalue - minvalue)
  2. Convert result of above formula in the range of 1 to 1000 using the below formula:
    score = (score * 999) + 1

The result will be the user’s score in the 1-1000 range for the user.

Validate the Security Advisor Plugin for User Risk Exchange

In order to validate the workflow, you must have Security Advisor scores. Syncing Intervals are defined during plugin configuration.

  1. Go to User Risk Exchange and click Users.
