Web Services Security (WSS or WS-Security) describes enhancements to SOAP messaging in order to provide quality of protection through message integrity, and single message authentication. These mechanisms can be used to accommodate a wide variety of security models and encryption technologies.
The scope of the Web Services Security Technical Committee is the support of security mechanisms in the following areas:
- Using XML Signature (new window) to provide SOAP message integrity for Web services
- Using XML Encryption (new window) to provide SOAP message confidentiality for Web services
- Attaching and/or referencing security tokens in headers of SOAP messages.
Options include:
- Username token
- SAML (new window)
- XrML (new window)
- Kerberos
- X.509
- Carrying security information for potentially multiple, designated actors
- Associating signatures with security tokens
- Each of the security mechanisms will use implementation and language neutral XML formats defined in XML Schema (new window).
