Adding Fingerprints Parent topic

  1. Navigate to Data Protection → Data Identifiers → Fingerprints.
    The Fingerprints screen appears.
  2. Click Add.
    A new screen appears.
  3. Enter the Source information. The source information describes the content to fingerprint and tells the system where to locate the content.

    Source Information Fields and Options

    Field/Option
    Description
    Name
    Name accepts up to 100 alphanumeric characters. Special characters are not allowed.
    Description
    Description accepts up to 256 alphanumeric characters. Special characters are not allowed.
    Repository Type
    Different information is required depending on the repository type.
    Local or NFS repository
    Local is the local file system on the management server. If the repository is part of the local file system or a mounted file system on the management server, you must set the Path (for example, /home/dgate/tmp). Host is not required when files to be acquired are located in the local file directory on the server.
    NFS: If the repository is part of an exported directory on an NFS server, you must set the following parameters:
    • Host
    • Path
    The Local/NFS folder must have “execute” permission. Otherwise, the DLP server cannot acquire fingerprints for files in local/NFS folder. This is due to the fact that a Linux system requires execution permissions of a folder in order to list files in the folder. The DLP server needs to list the files to acquire the fingerprints.
    Windows™ Share
    If the repository is a shared drive or directory on a remote machine that is running Windows™, set the following parameters:
    • Host (for example, myHostName or myHostIP)
    • Path (for example, /path1/path2)
    • Logon credentials for the remote machine (UserID and password)
    SharePoint
    If the repository is Microsoft SharePoint™, you must set the following parameters:
    • Repository Type: SharePoint
    • Host (for example, http://ishare.example.com/eng/dlp/)
    • Path (for example, shared documents/path)
    • Logon credentials for SharePoint (UserID and password)
    Note
    Note
    DLP Endpoint supports SharePoint™ 2003 and 2007.
    Remote Crawler
    If the repository type is Remote Crawler, a drop-down list field appears so that you can select the Host (the remote crawler registered to the management server).
    Machines names where your remote crawlers are installed can be viewed at Administration → Crawler Management.
    Note
    Note
    “Windows™ Share” and “Sharepoint” using the “Remote Crawler” is preferred because it is more dependable and private. DLP does not need a password to access the source configured on the remote crawler but requires a separate Remote Crawler download and configuration. See Remote Crawler Management.
  4. Click Test Connection to ensure that DLP can access the repository.
    Note
    Note
    Skip this step if you selected a Remote Crawler repository type, since DLP hides the Test button. You already tested the repository connection when you installed the remote crawler and configured the repository for the remote crawler.
  5. Enter Filter criteria to apply limits to the content being fingerprinted. This prevents unnecessary acquisitions that could affect crawler performance or cause you to exceed the fingerprints storage limit of 2GB.

    Source Information Fields and Options

    Filter Criteria
    Description
    Include
    Includes specific files or file extensions for the fingerprint acquisition. For example, you could specify one or multiple files.
    • DLP does not support folders since you specify the path/folder in the Path field.
    • Separate multiple entries with a comma but do not place a space after the comma.
    • You can use up to 200 characters.
    Example: example.doc,*.docx
    Exclude
    Excludes specific folders, files, or file types during the acquisition.
    • You can use up to 200 characters.
    • Separate multiple entries with a comma but do not place a space after the comma.
    Date Restriction
    Restricts the acquisition to files that have been modified within the specified date range.
    Source File Size
    Specifies that fingerprints should only be acquired for files within a file size range (in bytes, KB or MB). By default, the minimum file size is 61 bytes and the maximum file sizes are as follows:
    • Binary file: 32MB
    • Archive file: 32MB
    • Document: 75MB but only the first 6MB of extracted text is fingerprinted
    Note
    Note
    You can reconfigure the default minimum and maximum fingerprint settings at Administration → Server Configuration → Fingerprint Settings.
  6. Choose from the following options:
    • Save: Saves the settings only. Fingerprints will be acquired according to a schedule.
    • Save & Acquire: Saves the settings and then runs the fingerprint acquisition.
    The fingerprint definition appears in the Fingerprints Source list along with the acquisition status.
    Note
    Note
    The Last Acquisition column displays the last date that DLP acquired fingerprints for the content defined in the fingerprint definition.
