9. FAQs

Q. How does the Control Status get calculated?

Using a field named "scoreInPercentage" from the Defender API, which is equivalent to points achieved in the UI (but the UI shows it in points, while the API provides it in %), to determine if the configuration is done properly or not.

Examples

1. In the UI, the “Points Achieved“ is shown as 1/1, then the API response corresponding to that will be 100%, and the status will be "Completed." If the Status in the UI is "Completed," then in SAFE UI, the Control Status will be Qualified because the configuration is done properly.

2. In the UI, the "Points Achieved" is shown as 0/10, then the API response corresponding to that will be 0%, and the status will be "To address." If the Status in UI is “To address," then in SAFE UI, the Control Status will be Failed because the configuration is not done properly and needs to be remediated.

3. In the UI, the "Points Achieved" is shown as 0.89/9, then the API response corresponding to that will be 11%, and the status will be "To address." If the Status on UI is "To address," then in SAFE UI, the Control Status will be Failed because the configuration is not done properly and needs to be remediated.
