With today's security challenges and threats growing more sophisticated, perimeter defense alone is no longer sufficient. Few organizations are closed entities with well-defined security perimeters, which has led to the creation of perimeterless networks with ubiquitous access. Organizations need to have internal security systems that are more comprehensive, pervasive, and tightly integrated than in the past.

Cisco® Network Admission Control (NAC) Appliance, formerly known as Cisco Clean Access, provides a powerful host security policy inspection, enforcement, and remediation solution that is designed to meet these new challenges. Cisco NAC Appliance allows you to enforce host security policies on all hosts (managed and unmanaged) as they enter the interior of the network, regardless of their access method, ownership, device type, application set, or operating system. Cisco NAC Appliance provides proactive protection at the network entry point.

Cisco NAC Appliance provides you with all the information needed to understand, design, configure, deploy, and troubleshoot the Cisco NAC Appliance solution. You will learn about all aspects of the NAC Appliance solution including configuration and best practices for design, implementation, troubleshooting, and creating a host security policy.
