Procedures for Out-of-Band and Inline NAC

Policy Manager is not required for out‐of‐band NAC that utilizes RFC 3580‐compliant switches (Enterasys and third‐party switches). In this case, a VLAN is specified in NAC Manager to authorize connecting end‐systems with a particular level of network access, using dynamic VLAN assignment.

2. Define Network Security Domains

A different Security Domain should be defined for each area of the network that has its own unique requirements for end‐system authentication, assessment, and authorization.

A Security Domain defines a set of NAC Gateways and NAC Controllers that have common authentication, assessment, and authorization requirements for end‐systems connecting to the network. For NAC Gateways, the domain also includes the associated switches that are uniquely assigned to the gateways.

A Security Domain can be composed of both NAC Controller and NAC Gateway appliances. Each NAC Gateway can only be assigned to one Security Domain and therefore all ports on a particular switch (for example, a stack of SecureStack C2 switches or a Matrix N7 chassis) can only be associated to one Security Domain. Likewise, a NAC Controller can only be assigned to one Security Domain.
