    Network access control vendors pass endpoint security testing

    Posted June 21, 2010 - 1:33 pm

    One of the main promises of NAC is that you can ensure that endpoint security tools are up to date and that non-compliant machines can be identified or blocked. As regulatory compliance has grown in importance, NAC vendors have reacted by building strong feature sets aimed at endpoint security and compliance. In our NAC testing, we had good, and sometimes great, results across the board when it came to endpoint security.

    NAC: What went wrong?

    Posted May 24, 2010 - 11:33 am

    After spending four months in the lab testing the 12 leading network access control products, we’ve come to this conclusion: Five years of hype, buzzwords, white papers, product launches, standards battles and vendor shakeouts have resulted in very little in the way of clarity. Agreement on what NAC really means and the right approach to NAC remain as elusive today as in 2005, when the first NAC products burst on the scene.

  • Two-factor authentication through Windows Server 2008 NPS

    Posted May 10, 2010 - 11:19 am

    Increasingly, whether due to regulatory requirements or a basic recognition that static passwords just don't provide adequate security, organizations are implementing some form of strong authentication. Like all new efforts, before you start you want to be reasonably assured that you will succeed. In this tutorial we will document how to add two-factor authentication to various Microsoft remote access solutions through the Windows Server 2008 Network Policy Server. For two-factor authentication, we will be using the WiKID Strong Authentication Server - Enterprise Edition. WiKID is a dual-sourced, software-based two-factor authentication system.
