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_SQLServerConnectionString finds content that matches the pattern.
A keyword from CEP_GlobalFilter isn't found.
The regular expression CEP_PasswordPlaceHolder doesn't find content that matches the pattern.
The regular expression CEP_CommonExampleKeywords doesn't find content that matches the pattern.
