• Several protocols have emerged to address some of key areas of web service security based on Authorization, Authentication, Confidentiality, Integrity.

• Popular Specifications– SAML (Security Assertion Markup Language)

• authentication and authorization of web service– XML Digital Signatures

• encryption of XML messages – WS-Security

• WS-security addresses most of the above issues.• More information on Thursday by Dr. Sriram Krishnan
