 The vulnerability reports display the total number of vulnerabilities by severity (for example,
 Critical, High, Medium, Low, Info, Unknown). Below this, a table shows each vulnerability's detected date, status, severity, description, identifier, the scanner where it was detected, and activity (including related issues or available solutions). By default, the vulnerability report is filtered to display all detected and confirmed vulnerabilities.

+The Activity filter behaves differently from the other Vulnerability Report filters. The other filter options all OR together to show results from any vulnerability matching one of the filter criteria. With the Activity filter, the selected values form mutually exclusive sets to allow for precisely locating the desired vulnerability records. Additionally, not all options can be selected in combination. Selection behavior when using the Activity filter:
