Info

Security can be applied at two levels:► Enable gateway-level authentication► Enable operation-level authorizationEnable gateway-level authenticationProviding gateway-level authentication is actually nothing more than protectingthe URLs /axisengine and /soaprpcrouter with HTTP Basic Authentication. TheseURLs are of the channel application wsgwsoap1.ear and wsgwsoap2.ear. Weneed to modify the web.xml files of these EAR files. Extract EAR files, againextract wsgwsoap1.war, wsgwsoap2.war files and finally extract web.xml files tomodify.Example 7-5 BASIC security enabling for wsgwsoap1.ear and wsgwsoap2.earSOAP Entry Servlets/axisengine/soaprpcrouteryour role name - for example "meterable"BASICyour realm name - for example "WSGW Metered AccessArea"your security role - for example "WSGW meterablerole"your role nameMake sure to enable Global Security for HTTP Basic Authentication inWebSphere Application Server using the Admin Console as mentioned in “HTTPBasic Authentication” on page 143Note: Make a copy of the wsgwsoap1.ear and wsgwsoap2.ear beforemodifying them for enabling gateway-level authentication.156 IBM WebSphere V5.0 Security Handbook
Enable operation-level authorizationFirst of all, make sure you have enabled Gateway-level authentication beforeenabling operation-level authorization. The operation-level authorization is onlypossible for those Web Services that are deployed onto Web Services GateWay(WSGW) with the option Authorization Policy-Control access to this serviceselected.Providing Operation-level authorization is also nothing more than extendingWebSphere security for the beans to Web Services. That is the reason whyoperation-level authentication is also called Web Service Security - Role-basedauthorization.The implementation consists of writing a wrapper enterprise bean for the actualWeb Service component, making sure that the method calls are matching. Nowimplementing WebSphere Application Server's authorization methodology intothe wrapper enterprise bean will ensure that the Web Service component isinvoked only when the caller has appropriate authorization levels. We need toprotect the service component and the enterprise bean in the .ear file and applyauthorization rules to the EAR file.The following procedure will show you how to implement operation-levelauthorization:1. Create an EAR file:a. Go to /scripts/auth folder in the command prompt.b. Run the following command:WSGWAuthGen Where the is the URL for the gateway and isthe Name of the service as deployed onto the gateway (case-sensitive).For example:WSGWAuthGen http://myserver:port_number/wsgw CalendarThe your_service.ear file should now be created in the/scripts folder.2. Assign roles to protect methods:a. In WebSphere Application Assembly Tool (AAT), select File -> Open andfind the file wsgwauth.ear file under/installableApps.b. The following steps will import the your_service.ear archive into thewsgwauth.ear archive.i. In the navigation pane, open the pop-up menu for EJB Modules andselect Import.Chapter 7.
