General Symmetric key

  • مقالة

This SIT is also included in the All credentials bundled SIT.

Format

A combination of 44 characters consisting of letters, digits, and special characters.

or

A combination of 88 characters consisting of letters, digits, and special characters.

Pattern

A combination of 43 characters:

  • a-z (not case-sensitive)
  • 0-9
  • forward slashes (/) or plus signs (+)
  • ends with an equal sign (=)

for example:

abcdefghijklmnopqrstuvwxyz0123456789/+ABCDE=

or

A combination of 86 characters:

  • a-z (not case-sensitive)
  • 0-9
  • forward slashes (/) or plus signs (+)
  • ends with two equal signs (=)

for example:

abcdefghijklmnopqrstuvwxyz0123456789/+ABCDEabcdefghijklmnopqrstuvwxyz0123456789/+ABCDE==

Credential example

Confidence Band Example
High N/A
Medium N/A
Low key=abcdefghijklmnopqrstuvwxyz0123456789/+ABCDE=;

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 in general authentication process.

It uses several primary resources:

  • Patterns of Base64 encoded 256-bits symmetric key.
  • Patterns of Base64 encoded 512-bits symmetric key.
  • Patterns of CredentialName, CredentialFeatures, AccountIdentityName, AccountIdentityValue, ResourceType, ResourceName, Id, AccountName.
  • 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.
