Credential example

https://account.azurewebsites.net/api/function?code=abcdefghijklmnopqrstuvwxyz0123456789%2F%2BABCDEF0123456789%3D%3D

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

This SIT is designed to match the security information that's used to request Azure Function API when its authorization level is set a value other than anonymous.

It uses several primary resources:

  • Patterns of Base64 encoded 320-bits symmetric key.
  • Patterns of URL Encoded 320-bits symmetric key.
  • Patterns of CredentialName, CredentialFeatures, AccountIdentityName, AccountIdentityValue, ResourceType, ResourceName.
  • Patterns of mockup values, redactions, and placeholders.
  • A dictionary of vocabulary.

The patterns are designed to match actual credentials with reasonable confidence. The patterns don't match credentials formatted as examples. Mockup values, redacted values, and placeholders, like credential type or usage descriptions, in the position where an actual secret value should present won't be matched.
