+
+DTR scans images for vulnerabilities. At times, however, it may report image vulnerabilities that you know have been fixed, and whenever that happens the warning can be dismissed.
+
+1. Access the DTR web interface.
+
+2. Click **Repositories** in the left-hand menu, and locate the repository that has been scanned.
+
+
+    ![](../../images/scan-images-for-vulns-3.png){: .with-border}
+
+3. Click **View details** to review the image scan results, and select **Components** to see the vulnerabilities for each component packaged in the image.
+
+4. Select the component with the vulnerability you want to ignore, navigate to the vulnerability, and click **hide**.
+
+    ![Vulnerability list](../../images/override-vulnerability-2.png){: .with-border}
+
+    Once dismissed, the vulnerability is hidden system-wide and will no longer be reported as a vulnerability on affected images with the same layer IDs or digests. In addition, DTR will not reevaluate the promotion policies that have been set up for the repository.
+
+    If after hiding a particular vulnerability you want the promotion policy for the image to be reevaluated, click **Promote**.
