Part 6 - Securing Web Services with Single Sign-On
Web Services are arguably the most heterogenous distributed technology ever. A typical Web services setup will make use of many different technologies, object models and programming languages, which might include simple Perl scripts and standalone Web services implemented in C++ or Java, through to sophisticated applications build on top of J2EE application servers. Being able to interact across such diverse environments is one of the strengths of Web services, but it has a price: it becomes difficult to secure such systems. It is hard to find a common security standard for all involved technologies. Today we will talk about single sign-on, the security architecture that brings a flexible an interoperable way of securing heterogenous systems. Continue Reading
