WebSEAL is a high-performance, multi-threaded Web server that applies fine-grained security policy to the Tivoli Access Manager protected Web object space. WebSEAL can provide single sign-on solutions and incorporate back-end Web application server resources into its security policy. WebSEAL normally acts as a reverse Web
proxy by receiving
HTTP/HTTPS requests from a
Web browser and delivering content from its own
Web server or from junctioned back-end Web
application servers. Requests passing through WebSEAL are evaluated by the Tivoli Access Manager authorization service to determine whether the user is authorized to access the requested resource.
