Checksum

No

SITs that have checksums use a unique calculation to check if the information is valid. This means when the Checksum value is Yes, the service can make a positive detection based on the sensitive data alone. When the Checksum value is No additional (secondary) elements must also be detected for the service to make a positive detection.

Keyword Highlighting

Supported

When keyword highlighting is supported in the contextual summary for a sensitive information type or a trainable classifier, in the Contextual Summary view of activity explorer, the keywords in a document that were matched to a policy are highlighted.

Definition

A DLP policy has high confidence that it's detected this type of sensitive information if, within a proximity of 300 characters:

  • The regular expression CEP_Regex_AzureIoTConnectionString finds content that matches the pattern.
  • The regular expression CEP_CommonExampleKeywords doesn't find content that matches the pattern.
