Providing access control to dynamic URLs The current Web environment gives users immediate access to rapidly changing information. Many Web applications dynamically generate Uniform Resource Locators (URLs) in response to each user request. These dynamic URLs may exist only for a short time. Despite their temporary nature, dynamic URLs still need strong protection from unwanted use or access. Dynamic URL components Some sophisticated Web application tools use standard Web browsers to communicate with application servers through the CGI interface of a Web server. All these tools use dynamic URLs and hidden form elements to communicate the requested operation (with its parameter value) to the application server. A dynamic URL augments the standard URL address with information about the specific operation and its parameter values. The query string portion of the URL provides operations, parameters, and values to the Web application interface. Mapping ACL and POP objects to dynamic URLs WebSEAL uses the protected object space model, access control lists (ACL), and protected object policies (POP) to secure dynamically generated URLs, such as those generated by database requests. Each request to WebSEAL is resolved to a specific object as the first step in the authorization process. An ACL/POP applied to the object dictates the required protection on any dynamic URL mapped to that object. Because dynamic URLs exist only temporarily, it is not possible to have entries for them in a pre-configured authorization policy database. Tivoli Access Manager solves this problem by providing a mechanism where many dynamic URLs can be mapped to a single static protected object. Mappings from objects to patterns are kept in a plain text configuration file: /opt/pdweb/www/lib/dynurl.conf The location of this file (relative to the server-root) is defined by the dynurl-map parameter in the [server] stanza of the WebSEAL configuration file: [server] dynurl-map = lib/dynurl.conf You must create this file; the file does not exist by default. The existence of this file (with entries) enables the dynamic URL capability. http://www.ibm.com/sales/web/fortecgi.cgi?name=catalog&product=shirt&color=red Protocol Web Server Directory Path to CGI Program Operation, Parameters, and Values for Web Application Interface CGI Program File Base URL Query String Figure 21.
