Security Requirements for MPLS VPNs
•The Processing server can be added dynamically. The Watchdog will discover their existence when
you start up ISC.
•Each Collection server is responsible for a set of collection zones. Each zone has one Collection
Server.
•Both Processing servers and Collection servers failover to the Master server automatically.
•Each device belongs to a zone, but a device can be relocated to a different zone as needed.
If the service provider has implemented one or more Processing servers or Collection servers, all the
servers—Master, Processing, and Collection servers—are listed in the Administration Control Center.
The Remote server can be installed from the Control Center as well.
All Remote servers are monitored by Watchdogs. Remote Watchdogs report statistics to the Master
Watchdog. You can start and stop all the servers from the Administration Control Center. Logs are
available for viewing in real time.
