The following list highlights key features:
■ Enforcement options – NAC 800 provides multiple enforcement
options for quarantining endpoints that do not comply with your
security policy (Inline, DHCP, and 802.1X). This enables NAC 800 to
enforce compliance across complex, heterogeneous networks.
■ High availability and load balancing – A multi-server NAC 800 deploy-
ment is mutually supporting. Should one server fail, other nodes
within a cluster will automatically provide coverage for the affected
network segment.
Load balancing is achieved by an algorithm that spreads the endpoint
testing load across all Enforcement servers in a cluster.
■ Multiple-user, role-based access – In enterprise deployments
numerous individuals, each with varying responsibilities, typically
require access to information within NAC 800. Role-based access
enables system administrators to control who has access to the data,
the functions they are allowed to perform, and the information they
can view and act on. Role-based access ensures the integrity of the
enterprise-wide NAC 800 deployment and creates the separation of
duties that conforms to security best-practices.
