Entitlement engine (XACML engine) of WSO2 Identity Server, is based on the Balana XACML 3.0 implementation. But If you search through WSO2 Identity Server distribution, it provides separate set of configurations to configure the entitlement engine. Basically for defining the attribute finders and policy finders, it uses a property file called “entitlement.properties” which can be […]
XACML
According to the XACML specification, there are lot of extension points that provide the flexibility to extend a XACML engine. Balana XACML 3.0 implementation supports most of those extension points. Such as 1. Attribute finders 2. Policy finders 3. custom XACML function 4. custom combining algorithms 5. custom datatypes. In this blog post, I will […]
Balana is one of open sourceXACML implementation that supports XACML 3.0. If you need to do some testing on Balana or integrate the Balana with any other component, this blog post would be useful. Here i am going to explain how we can get start of Balana. Approach 1. This is the easiest way. Just create […]
[Please note latest Balana source can be found from here https://svn.wso2.org/repos/wso2/trunk/commons/balana/ It is trunk and source will be moving to github ] It is pleased to announce the M1 release of WSO2 Balana 1.0.0 WSO2 Balana is an open source implementation of XACML, which support XACML 1.0, 1.1, 2.0 and 3.0 specifications.

XACML is the powerful way to build access control systems in your application. Here we are going to talk about how we can build a XACML driven authorization for on-line trading application called “K-Martket” This sample is shipped with Balana XACML implementation which can be found at here. Scenario would be as follows…. 1. K-Market […]
Resource filtering is one of useful and powerful feature that comes with XACML. Basically this would become more popular with XACML 3.0 due to multiple decision profile. With multiple decision profile, PEP can ask authorization for multiple resources for the PDP, Where your PEP can only filter out the permit results. Let try filtering sample […]
WSO2 Balana is the latest open source XACML implementation based on sun-xacml. Currently WSO2 Balana support XACML 3.0 specification with Multiple decision profile. You can find the Balana source from here. When you just go through the source of Balana. It is just similar to sun-xacml source and XACML 3.0 specification has been implemented as […]

However i am not going to talk about Balana today… But just want to share some knowledge with XACML 3.0 When I go through the XACML 3.0 Core specification, following are […]
In my previous post, I explained some important things about “EntitlementService“. According to them; when we are writing a PEP client, we need to consider about followings. Before, Please note that EntitlementService is admin service according the WSO2 Carbon platform. Therefore WSDL of admin service can not be seen by default and you can not access […]
XACML specification clearly defines the externalized architecture, by separating the PDP PEP components. PDP decides authorization decisions where PEP can talk to PDP and get those decisions. Therefore it is better to have a standard way of doing PEP and PDP communication. Because in a deployment any application (PEP) could communicate with any PDP irrespective […]
