Challenges of Future IAM (concerned with Mergers , Acquisitions, Startups)

When the companies bring in external users to work within the enterprise activities, via mergers, acquisitions, outsourcing and allowing end users come via social login, a problem is raised due to the variety of protocols each of these external parties may use for identity management. Most of the time these external parties would not agree to share their user base with sensitive information of the users, which is a major asset of them. In this case identity federation or cross domain authentication comes into provide a solution to this problem. There are identity federation protocols that have evolved with the time mainly OpenID, SAML, WS-Federation and OpenID connect to address the requirement of federated authentication. Even though these protocols have been able to cater for it, while the acquisitions and merges grows up in numbers the solutions still suffers from two major limitations, namely[1], Federation Silos

When there is federation requirement, organizations would choose on…

Future of Identity and Access Management (IAM)

When a business needs a rapid growth or a new technology integrated, partnering and acquiring strategies are commonly put forward. WhatsApp been acquired by Facebook, Skype been acquired by Microsoft are such popular acquisitions done by the giants in the industry. According to the Wall Street Journal “2015 the biggest year ever for mergers and acquisitions” globally[1]. When this is considered from the aspects of enterprise identity management, it means the rapid merge of external users to current enterprise system. While this merge needs to happen rapidly in order to take the competitive advantage, privacy and security aspects cannot be ignored. Quocirca which is a primary research and analysis company also confirms that “many businesses now have more external users than internal ones. Many organisations are putting in place advanced identity and access management tools to facilitate the administration and security issues raised by this.”[2]. 
The impact of these merges and acquisi…

Worth of Bitcoins

Bitcoins seems to be an interesting subject and is been taking the hype recently.

If we look at the value of a Bitcoin over the range of years, at 2015 it was worth $250 and now it is going beyond value of $2500 at the moment. This is capable of attracting more people towards it. We will proceed with more posts to understand Bitcoins, how to use it and any useful information for anyone interested in moving forward with Bitcoins, which I think is the currency of the future.

Following captured from on 8th June 2017 shows the value deviation of bitcoin from it's very start.

Why Identity Mediation? And a Language ?

As identified and predicted by several prominent analyst firms(Forrester, Gartner) , acquiring and merging has been the frequent mechanism for enterprises to expand in the recent past and the years to come. With this expansion there is a rising need for enterprises to handle the enterprise across identity and access management procedures in a secured way that is fast enough to have the competitive advantage of the merged or acquired assets. With different enterprises having variety of standards and protocols in use for identity and access management, catering for this requirement is absolutely challenging given the time factor. A similar situation has been addressed by Enterprise Service Bus(ESB) concept few years back, when the requirements raised to mediate between different transport protocols and data formats when communication is required between disparate enterprise systems that are legacy and modern.

We are trying to apply the same concepts around ESB in the arena of identity …

WSO2 Identity Server - Extension Points - Part 3 - XACML

This is the third of a series of posts on extension points available in WSO2 Identity Server, with relevance to separate protocols.
Previous posts can be found at, WSO2 Identity Server - Extension Points - Part 1 - SAMLWSO2 Identity Server - Extension Points - Part 2 - OAuth With the XACML architecture there are 4 main separate components as, PIP (Policy Information Point) - serves information required for policy evaluation.PAP (Policy Administration Point) - serves capabilities to govern the policies.PDP (Policy Decision Point) - make decision on incoming requests whether to permit or deny based on the defined policies and information collected from PIP.PEP (Policy Enforcement Point) - the interception point which checks and honors the policy decision.
WSO2 Identity Server can act as all these 4 components. In this post we will check on the extendability of these components and their usages. Policy Information Point(PIP) modules Usage:
When the information available locally is not eno…

WSO2 Identity Server - Extension Points - Part 2 - OAuth

OAuth2 is widely used in the enterprise today for authorization aspects of APIs. This is the second post on the extension points available in WSO2 Identity Server after WSO2 Identity Server - Extension Points - Part 1 - SAML

All the implementation using following extension point needs to be configured at <IS_HOME>/repository/conf/identity/identity.xml file under the element OAuth.
1. Custom OAuth grant handlerUsage: When we need to support an OAuth flow that is different from standard grant types. Validates the grant, scopes, and access delegation.
2. Client Auth Handler
Usage: When the client credential authentication needs to be customized. By default we validate the client id and secret.
