Create a Classification

Use classifications in your Shadow/Web DLP Policies to identify sensitive data. A range of built-in classifications are provided for complying with various regulations, or you can create custom classifications, using criteria such as keywords, regular expressions, file type, and more.

  1. Go to Policy > DLP Policies > Classifications

    • Advanced Pattern. Regular expressions or phrases used to match data, such as dates or credit card numbers. Select a Skyhigh Security built-in advanced pattern, or customize your own. Set a threshold to reduce false positives by editing the number.
      TIP: Click the name of a Skyhigh Security Advanced Pattern to view all its details. You can also click Check Usage to see if the selected Advanced Pattern is being used in other classifications.
    • Dictionary. Collections of related keywords and phrases such as profanity or medical terminology. Add a Skyhigh Security built-in dictionary, or customize your own. Set a threshold to reduce false positives by editing the number. 
      TIP: Click the name of a Skyhigh Security Dictionary to view the keywords and phrases included in the Dictionary. You can also click Check Usage to see if the selected Dictionary is being used in other classifications.
    • Keywords. Specify a string value. You can add multiple keywords, separated by commas. Keywords are not reusable in other classifications. Enter keywords, separated by a comma. Any match will count as a detection. 
    • File Size. Specify the minimum or maximum size of the files you are interested in. ‘Between’ allows you to define a range. Choose from:
      • is less than
      • is greater than
      • is between
    • True File Type. Specify the true file type to determine which files to detect. For example, a .cpp file saved as a .txt file can be detected using the true file type classification criteria. Select from the Skyhigh Security built-in true file types.
      TIP: Click the name of a Skyhigh Security True File Type to view its details.
    • File ExtensionSupported file types you want to apply the classification criteria, such as MP3 and PDF. Select Skyhigh Security built-in file extensions, or customize your own.
    • Location in File. Select the section of the file to look for the classification criteria. For Microsoft Word documents, Header, Body, and Footer can be identified. For PowerPoint documents, WordArt is considered the Header, and everything else is identified as the Body. For all other documents, matches are only found in the body of the text
      Select from:
      • Header
      • Body
      • Footer
      • within the first characters
         
  5. Enter the Keywords separated by commas: Confidential, Sensitive, Secret
