Components

openNAC Enterprise solution is the next step in the evolution of data Network Access Control Solutions. openNAC is a simple but feature-rich and flexible solution to build and control enterprise Network Access, that combines existing OpenSource technologies with advanced features.

The first step to build a reliable, useful and successful openNAC is to define a clear design. This design needs to be aligned with the expected NAC use cases, and it needs to describe which data center components are going to be part of the openNAC Infrastructure. This comprises: - All the infrastructure components such as Core, Sensor, Analytics, Third parties and Network devices - Planned sizing of openNAC (characteristics of the workload, numbers of users, types of authentication and so on) - Provisioning workflow, ie, how end users are going to be isolated and using the NAC Solution.

In order to get the most out of a openNAC infrastructure, we recommend that you create a plan with the features, number of users, types of authentication, scalability, and high availability characteristics you want in your deployment. This Chapter provides information to plan an openNAC. With this information, you will be able to easily architect and size your deployment, as well as understand the technologies involved in the management and their relationship.
