Domino Fingerprinting Wizard - Attachment Filtering

Use the Attachment Filtering page of the Domino fingerprinting wizard to use the attachment type, size, or both to determine which attachments to scan.

Steps

  1. To scan for specific attachments, mark Filter by Type, then list the types of files to be fingerprinted, separated by semi-colons.

    Optionally use the “*” or “?” wildcards. For example, “*.doc; *.xls; *.ppt; *.pdf”.

  2. Use the Except field to list the file types to exclude from the scan, separated by semi-colons. Wildcards are permitted here as well.
  3. To filter based on file size, mark Filter by Size, then select one or both of the following options:
    • Mark Scan only files larger than, then select a file size from the spinner. By default, all files larger than 1 KB are scanned.
    • Mark Scan only files smaller than, then select a file size from the spinner. By default, all files smaller than 100,000 KB are scanned.
    Note: Files larger than 100 MB are fingerprinted for exact- matching. Two binary fingerprints are created: one with the first 100 MB, and another with the first and last 5 MB. When a large file is received, the first and last 5 MB are sent to analysis. They are compared to both of the fingerprints above to search for a match.
  4. Click Next to continue.
