10. Create a Security Vulnerability Assessment Worksheet

  1. Reset the filters or reload the tool
  2. Use one of the following methods to select attacks of interest from the data in the tool.
    • Use cursor to highlight individual items
    • Use filters to select groups of items, for example, enter a text string, such as "buffer overflow", or "SQL injection", or, select one or more reference lists, such as "OWASP 2021" or "CWE Hardware". Afterward, use the "Select Data" button and "Select Filtered Data"
