Description |

SAML is a standard for exchanging authentication and authorization data between security domains. SAML uses security tokens containing assertions to pass information about a principal (usually an end user) between a SAML authority, (identity provider), and a SAML consumer, (service provider). SAML assertions are usually made about a subject, (user) represented by the <Subject> element. The confidentially of the data in a message as the message is passed through an intermediary web service may be required to be restricted by the intermediary web service. The intermediary web service may leak or distribute the data contained in a message if not encrypted or protected. |

Ask the application representative for the design document. Review the design document for web services using WS-Security tokens. If the application does not utilize WS-Security tokens, this check is not applicable. Verify all WS-Security tokens are transmitted via an approved encryption method. If the design document does not exist, or does not indicate all WS-Security tokens are only transmitted via an approved encryption method, this is a finding. |

Encrypt assertions or use equivalent confidentiality when sensitive assertion data is passed through an intermediary. |
