Title : Cisco NAC Appliance : Enforcing Host Security with Clean Access


The Cisco Self Securing Network platform is currently structured around several cornerstone technologies of which the Cisco Clean Access technology is a leading component. The Cisco Clean Access technology is one of several industry wide Network Admission Control (NAC) technologies which rely on a combination of client-server components. The Cisco Clean Access suite includes a client component which could be host-installed applet or a browser based applet that can read basic configuration data from a host machine and communicate compliance to enterprise defined rules/policies which are pre-defined on a clean access server appliance and other coorperating systems. The book, Cisco NAC Appliance is a good guide for administrators deploying this complex set of solutions brought from Perfigo Inc. after Perfigo’s acquisition by Cisco 2006.

The book’s organization and tone is aimed at security architects, security managers and security administrators. While a security architect will better understand the various deployment options and thus the place of the Cisco NAC framework in an enterprise, security managers will get a comprehensive enough view of the Cisco NAC framework to make the judgment call on actual deployment of the infrastructure and of course make decisions on cost/facility and better grapple with the potential cost benefit requests from enterprise’s executive and the security administrator will have a quick guide handbook to help wade through the myriads of documentations from Cisco on its evolving SAFE architecture in general and the NAC framework in particular.

The organization of this book is excellent for the intended audience; six parts covering the basics of host security landscape, design of Cisco NAC appliance, developing a host security policy, the Cisco NAC configuration, some deployment best practices, and of course NAC appliance maintenance and troubleshooting. The six parts are laid out in fifteen accessible chapters spanning more than 500 pages with generous amount of configuration examples and screenshots.

With Cisco now having more than 45% market share in the endpoint access control market, books like these can only increase in importance as a guide to organizations grappling with the decision on what and where to deploy these technologies.

And for this volume, the taste of the pudding remains in the eating. So if you don’t have a copy yet, go grab one (so long as you are interested in some endpoint security solutions now or at some point in the future). As for rating, I’ll give it my best rating so far, four star out of five.
