• Created Domains for different teams to access this secure device based on Rule Based Management Configurations as a part of administration.
• Created a Multi Protocol Gateway that accepted all requests. XSLT was used for checking for a WS security username xml tag. For internal users, the message wasn’t encrypted. The necessary rule to perform the authentication and authorization using a AAA action was called.
• Requests coming from external clients lacked username token, which was encrypted, these were routed to a specific rule where signature was verified and subsequent decryption of the request was done. Then a check for WS Security username token or SAML assertion was performed, and then routing to the appropriate rule was done to perform authentication and authorization using a AAA action.
• LDAP was used for Authentication and Authorization which was integrated with the Data power
