Network Admission Control
Network Admission Control (NAC) protects data networks from computer viruses
by assessing the health of client workstations, ensuring that they receive the latest
available virus signature updates, and controlling their access to the network.
NAC works with antivirus software to assess the condition of a client, called the
client’s posture, before allowing the client access to the network. NAC ensures
that a network client has an up-to-date virus signature set which ha s not been
infected. If the client requires a signature update, NAC directs it to complete the
update. If the client has been compromised or if a virus outbreak is o ccurring on
the network, NAC places the client into a quarantined network segment until
disinfection is completed.
