This whitepaper discusses best practices for achieving successful implementation of NAC, covering topics such as:

• Key success criteria for a successful network access control (NAC) implementation
• Methods for integrating into existing infrastructure (i.e. Cisco only networks) and mixed-vendor network environments (i.e. Cisco, Extreme, Foundry, Juniper, etc.)
• Process steps for defining and implementing network access control policies and their enforcement actions to improve access control and security while minimizing disruptions
• Recommendations on the process for deploying network access control without affecting productivity
