In January, I published an article through developerWorks on protecting your website with some of the new features of the ISAM for Web and ISAM for Mobile appliances.
It’s available here:

It makes use of Virtual Host Junctions, WebSEAL authentication levels and the comprehensive context based access engine and one time password capabilities in ISAM for Mobile.
It has some neat features including device registration through fingerprinting, and the ability for users to self manage their own registered device list.
If you can handle my commentary, here is a YouTube video demonstrating the scenario.
