Efforts to modernize enterprise infrastructure have never been more complex. While the need is certainly there on multiple fronts – competitive edge, cost savings and new business initiatives, to name just a few – new hurdles seem to pop up no matter where an IT administrator might look. That includes not just management issues such as cap/ex costs and user resistance, but also an increasing pancake stack of integration layers within and among applications. New-generation software tools, legacy development tools, back-end data resources, hardware infrastructure – all elements need to play nicely, but few really do.

Enter single sign-on – and open source software – as a way to facilitate the interoperability required.

The benefits of single sign-on (SSO) – often viewed as a security-specific solution – go far beyond simple IT modernization. Certainly, anything that eases the integration burden of new additions to the enterprise software portfolio or SOA stack is a good thing.

But SSO can also yield direct bottom-line savings in reduced support costs. Users ringing help-desk phones about lost passwords to a dozen or more local and Web-based applications will certainly consume IT personnel less if they only have to worry about a single credential. With industry estimates putting the cost of one help-desk password problem request at about $30 per incident, many organizations can completely cost-justify an SSO project right there.

IT management will also have an easier time enforcing more stringent security measures, including strong passwords and session encryption, if users know they only need to imprint a single such credential in their heads. IT administrators will also run into far fewer broad security exposure situations, such as the lost laptop that contained Word documents with executive-level passwords to half-a-dozen critical applications mixed in with the user’s online IDs, including the one for the bank.

The idea of single sign-on (SSO) has been around for years. It’s the central part of any identity management solution. The idea is simple – user authentication across multiple systems with a single set of credentials. But until recently, actual reports of full-on enterprise-wide single sign-on solutions have been as frequent – and reliable – as Yeti sightings.
