Prabath Siriwardena, WSO2’s senior director of security architecture, has a lot to be proud of. He’s an accomplished author, speaks at conferences such as Qcon, ApacheCon, WSO2Con, EIC, IDentity Next, OSCON and OSDC, and has over a decade of experience working with Fortune 100 companies.
We caught up with Prabath recently to get his take on the significance of GDPR, the future of open source IAM solutions, his personal journey at WSO2, and why he believes the world always needs fresh ideas.
1. What has your journey at WSO2 been like, Prabath?
I completed 10 years at WSO2 last year, having joined on the 1st of November 2007. It’s been a great journey with an awesome set of people around me - both the colleagues at work and the customers. I’ve learned a lot from both these groups. The joy of working at WSO2 is that you always get an opportunity to help someone solve a challenging problem. It can be as simple as building a federated login scenario with a SaaS vendor to more complicated use cases like building an identity architecture to accommodate millions of users. Overall it’s a very satisfying, rewarding journey - looking back, I’ve enjoyed every second of it.
2. What’s the most recent problem you’ve helped solve?
I get the opportunity to talk to and work with many WSO2 customers, each problem is quite interesting. Engaging with customers allows me to understand their pain points. Once you know their pain points, you can work with them to find and build a solution.
Let me give you one example. Recently we worked with a customer based in San Francisco, California, a large company with hundreds of departments. Each department has its own applications and an identity store. The employee records are scattered between those different identity stores - and a given employee has to maintain multiple records under each department if they have to access any of the applications provided by that department. This has been the way the company operated for several years. A real productivity killer - but, convincing 100+ departments to build a unified identity platform across the company was challenging, both technically and politically. We’ve had several long discussions with their technical teams and is now in the process of building a unified identity platform with WSO2 Identity Server, in a phased approach.
3. GDPR has surely caught on and everyone is throwing this term around. But there’s a deadline approaching and we need to act fast. What’s the simplest way an enterprise can get started and what do they need to keep in mind?
GDPR is a historical milestone in all the initiatives brought up so far to protect consumer privacy. Even though it’s more applicable to EU, it has a global impact in the way it’s designed. Becoming GDPR compliant starts with a self-assessment - understand what data you collect from your employees, partners, suppliers, customers, and any other entities you work with. Then you need to see how the data is being stored and processed. If you occupy third parties in the process of data collection - or if you share data with third parties for further processing, then you also need to worry about them being GDPR compliant. Once that’s done, you can come up with a phased approach to be GDPR compliant. It’s always recommended that you consult a lawyer or any GDPR consultancy firm to validate your approach and get their guidelines. GDPR is a law, so you should not mess with it!
There are no all-in-one or tailor-made solutions for GDPR. This is where WSO2 Identity Server has a key role to play. WSO2 Identity Server, as an identity provider, gets directly involved in processing personal data. We have made the product GDPR compliant and also provide a portal for consent management.
4. What’s the future like for open source IAM solutions?
A decade back, the IAM market was mostly dominated by Oracle and IBM. The entry barrier was high and was not justifying the cost over the benefits.
Today the number of companies occupying an IAM solution is much better. Cloud-based IAM solutions and open source IAM solutions increasingly reduce the cost of entry. According to Gartner, by 2021 open source IAM components will be used for one or more IAM functions by 30% of organizations, up from 20% at the end of 2016. Apart from open source, there are a large number of companies that use homegrown IAM solutions - around 20%. In the next few years, I would expect these companies using homegrown IAM solutions to select an open source IAM product. Unless you have a dedicated set of engineers, who have expertise on IAM, it’s hard to keep up with the pace in which the IAM industry is evolving.
Another important fact I would like to highlight here is open source licensing. Not all open source licenses give you the same level of freedom. Apache 2.0 is the most business-friendly open source license. You can do anything with a product released under Apache 2.0. All WSO2 products are released under the Apache 2.0 license and WSO2 is the 8th largest open source software company. There are more than 100 Universities in USA and Canada, using WSO2 Identity Server for free, with no support from WSO2. That’s the beauty of real open source.
5. What are the benefits of an open source IAM solution?
There are multiple reasons why someone would pick an open source IAM vendor over commercial off-the-shelf (COTS) software. At one point, COTS had an edge over the features, but no more. Most of the open source IAM products out there can compete with any COTS product, in terms of features, and of course, perform better.
Then the cost. Most of the open source products do not have any licensing cost, but a production support model. This definitely reduces the initial product purchasing cost. One key reason I see why people go for open source IAM products is the ‘freedom’. The freedom to examine the source code, freedom to extend the capabilities, and freedom to make business decisions.
That’s about scalability, how about security? Irrespective of a product being open source or not, you need to worry about the security of the product. At WSO2, we put a lot of effort into building all WSO2 products in a secure manner. We use both open source (OWASP ZAP) and commercial code scanning tools (Veracode, IBM AppScan). All these tools are integrated into the build system and no product releases are done without fixing any of the reported issues.
6. How did you start working in IAM?
It just happened. When I joined WSO2 in 2007, I was assigned to the WSO2 Identity Server team. At that time it was called, ‘Identity Solution’ - and we only had 4 members in the team. WSO2 was founded in 2005, where SOAP, SOA, web services were at the top of the hype. We had a strong, solid foundation in that space. Both of our founders are pioneers in the web services domain, and authored many key web services specifications. Axis2, Synapse, Rampart, WSS4J are top open source Apache projects initiated and mostly contributed by WSO2 employees at that time. Apache Rampart is the web services security module for Axis2 - and it has all WS-Security, WS-Security Policy, WS-Trust specifications covered. Around 2006/2007 we were closely working with Microsoft for interop testing, and that was the time Microsoft came up with an open specification called ‘Information Cards’, which is based on WS-Security and WS-Trust. Since we already had them implemented in Rampart, it only needed a little more effort on top of that to build support for Information Cards. That’s how the WSO2 Identity Server was born in 2007 - and it was one of the very first implementations of Information Cards in Java.
7. What is your proudest accomplishment in recent times?
WSO2 Identity Server celebrated its 10th anniversary in December 2017. Looking back, there are many proud moments that were accomplished as a team. Today, WSO2 Identity Server is a globally recognized brand and is one of the top open source IAM products. There are more than 40 million users globally using WSO2 Identity Server for authentication on daily basis. There are more than 100 paying customers, which we are extremely proud of. Just to name a few, Nissan, HP, GE, Verizon, Vodafone, Seagate, Department of Homeland Security (DHS), Verifone, Align Tech, WEST, Nutanix, Trimble and many more. It’s extremely satisfying to see how the product evolved over the last 10 years and is now trusted by many Fortune 100 and Fortune 500 companies to build the most critical parts of their core business on top of WSO2 Identity Server.
8. What advice would you like to give a budding developer or an architect to better their career?
Failing to innovate is the biggest failure in anyone’s life. The world does not lack technical skills, but fresh ideas. Fresh ideas are born when you start feeling your problems and those of others. You may choose to live with the pain or get rid of it by fixing the problem. The latter leads to innovation. There is always room for improvement, room for innovation. Capitalize on those and enjoy what you do.
