You can do this by marking those detections as ignored. When you ignore a detection, you'll be prompted to give a reason - false positive, acceptable risk or not applicable. The status label is grayed out in the list and, by default, the detection will not appear in future reports on the same web application unless you specifically configure them to include ignored detection.
On the Ignore Detections (s) window go to Reactivate the Ignore detection(s) after section . Specify the number of days or a date after which the detection should reactivated again. Show meShow me
The Ignore option is not available for Information Gathered detections.
To ignore a detection, select or hover over a detection row (vulnerability or sensitive content), and from the Quick Actions menu, click Ignore. To ignore detections in bulk, select multiple detections, and from the Actions menu, click Ignore.
