I have written my web services using apache axis2. Now I want to make my web services secure to avoid unauthorized access.
Is there any way in apache axis by which we can redirect each web service request to a particular web service ? so that it will do authentication and on successful authentication it will forward the request to respective web service.
Thanks,
Ajinkya.
you can use Apache Rampart[1] for this. Instead of redirecting to another web service you can use UT (user name token) to authenticate the uses. Using WS-Security is the correct way to secure a web service. This[2] would help you.
If you interested WSO2 AS[3] provides a integrated environment for web service deployment and add security using its GUI. Further since it is based on WSO2 carbon platform you can integrate your user store with WSO2 AS and then authentication is provided out of the box.

I am new to this wso2 evaluating wso2,
I am using Identity Server I have web application , want to apply web SSO feature using WSo2, I had check there are soap web service present in wso2 for UserAdmin,
https://server-info:9443/services/UserAdmin.UserAdminHttpsSoap12Endpoint/ using soap client for test , for dev have to write java client for request
but did not find any web services related WEB SSO for example I require authentication web service which will accept Username/password return some token information and using that token I can store in session for single sign out
Is there any web service/ API in wso2 provide authentication? or what is best approach for implement SSO using wso2 for web applications.
Thanks
If you are looking for SSO with WSO2IS, WSO2IS supports several standard ways to achieve it. They are,
SAML2 SSO
OpenId Connect
OpenId
Passive STS (for windows based applications)
From above, most popular way is to use SAML2 SSO or Openid connect. Your web application also must support to talk with WSO2IS using above standards. Say, if you need to achieve SSO using SAML2 SSO. You application needs to send the SAML2 Request and process the SAML2 Response in standard way as mentioned in SAML2 SSO spec. You can find a sample web application that has been implemented to work with WSO2IS from here. This blog contains all configuration details that you need to do in WSO2IS side as well. You can even use the sample web application with other SAML2 IDP as sample web application is talking in standard way. Also. if you are looking for Openid connect, you can find another sample web application from here with config details. I hope this would be a good starting points for you.
Does anyone know if the WSO2 Identity Server exposes a web service endpoint/URI to which I can send XACML requests via HTTP(S)? I am aware that they provide an API for doing this, but I have a situation where I can't use that, but I can do HTTP requests.
Thanks,
Jim
P.S. For the record, I think I've found my answer, mostly deduced from this page:
http://wso2.com/library/articles/2013/11/fine-grained-xacml-authoriation-with-pip-points/
That page tells how to enable WSO2 to unhide the WSDL for the EntitlementService web service.
Yes, you can enable the entitlement service wsdl and call it from external systems according to your requirement to send requests. By default this admin service is disabled. You can read more about it at PDP PEP Communication – how WSO2 Identity Server defines
WSO2 Identity Server : I am new to WSO2 Identity Server. Could somebody help to get list of REST call and soap call supported by WSO2 Identity Server
This blog post has an example of using WSO2-IS APIs.
Take a look at the answer to the following question also. WSO2 identity server api
WSO2 products are manage internally SOAP web services known as admin services. The admin service wsdl as bellow.
https://localhost:9443/services/UserAdmin?wsdl
Note: you cannot view the wsdl of admin service by default due to security reason. Configure the following steps to enable and invoke the admin service wsdl.
Set the <HideAdminServiceWSDLs> element to false in <IS_HOME>/repository/conf/carbon.xml file.
<HideAdminServiceWSDLs>false</HideAdminServiceWSDL>
Restart the server.
Also you can use OSGi console to get the list of SOAP Services exposed in Identity Server and view the available service components details. To enable osgi console doing following steps.
Get osgi console by executing the following command.
<IS_Home>/bin/wso2server.bat –DosgiConsole
After successfully started the server press ‘Enter’ key and osgi>console will be displayed.
To get all admin services that are deployed on this server.
osgi> listAdminServices
List down all hidden services that are deployed on this server.
osgi>listHiddenServices
All services expose Web Service APIs which can be used for to gain access to back end functionality.
I have a webapp which has jsps. am not using any struts or mvc framework. We have JAX-RS service build using Apache CXF.
Now i want to do following
Allow user to login with username and password.
For all subsequent calls to webservice, same authentication info should be used.
Logged in user has some details (profile photo, full name), which i want to keep it constant across session.
Also, its role are defined. Based on role(s) only certain jax-rs calls will be allowed.
Roles are also used in JSP to restrict access to functionality.
Web services can be accessed outside so authentication and authorization info should be used.
As far as i understand, We should not use session in jax-rs services. What is the best way to handle above situation ?
The best way depends on how you estimate it.
My way of doing this is to
Run Rest service and JSP on the same instance
Use web.xml and CXF to set up security policy, which allows user/pw authentication and authorization, ROLES binded to both jax-rs urls and JSP urls.
Based on 2, jax-rs services can be called directly outside, but user/pw is required as you specified.
Hope this can help you a bit.
Think cxf security validation as any other http or https validation. you have to intercept the request and pass it to the rest service. You can use any of the tools like siteminder, else can write CXF interceptor to do your own security validation. In the interceptor you can call SSO kind of token generator server in case you have the infrastucture or call the DB if your architecture is built that way. You can use caching to reduce the resource hits and can look at custom or hibernate cache. enabling Https has to be done in server configuration. If you have certificate , you can use the same else you can generate your own using openssl.
I have the following scenario:
I have an application (html files + javascripts hosted in a webserver)
There is a SOAP web service that we need to develop.
Web service will be called from java script (AJAX calls).
User will access the application in intranet scenario. Users are validated against active drectory.
Requirement states that user need to be logging in using logged in users network credentials. There should not be a login screen shown to user.
Web service interfaces need to be invoked with logged in users credentials. A login inteface of web service specifically needs to be called as first call.
I have a specific question on how to pass user credential to web service.
I am planning to configure Integrated windows authentication (NTLM) for web application to avoid login screen.
However I do not know a way to capture and send user id and password to login interface of web service.
Most of the questions and answers around this topic has been for microsoft technlogies. Any specific ideas?
Further research and several blog posts pointed me to Kerberos authentication and a single sign on framework. With NTLM i cannot delegate credentials to web service. However with Kerberos i can. I will be using SPNEGO and delegate the credentials after authentication. Please refer to below link for further details.
