Deploying a single Network Security software node

features such as the ability to block specified traffic from entering the
network.
Passive deployment: Both software and appliance nodes can be deployed in
■
passive mode, and positioned near the network, where they do not impede
network performance as a point of failure. No service is ever lost, even if the
node fails. The possibility of failure can be mitigated by failover groups that
maintain the availability of all nodes.
See "Establishing high availability failover"
Symantec Network Security can be deployed as one or more single nodes that

7100 Series appliance node, a fictitious network, and a possible intruder:
