25 Barracuda NG Network Access Client - Administrator’s Guide
2.4 Access Control Service Trustzone
Each Access Control Service belongs to a so-called trustzone. To enable a company to enforce their
security policies across multiple Barracuda NG Firewalls the Barracuda NG Control Center provides
Access Control Service Trustzones as global objects. This advanced feature allows all Access Control
Services within the same trust zone to share the same set of security policies. In addition they share
a signing key, so that a mutual trust relationship can be established.
On stand-alone Barracuda NG Firewalls, configuration of the trustzone is located in the configuration
node
Virtual Servers > <servername> > Assigned Services > <servicename> (Access Control
Service) > Access Control Service Trustzones.
The Barracuda NG Control Center provides Access Control Service Trustzones either within the
Global Settings directory or specifically as Range Settings or Cluster Settings. As usual these objects
permit access only to administrators with appropriate administrative scope and appropriate
permission.
Access Control Objects provide an hierarchical override mechanism. Objects on cluster level sharing the same name
as global or range objects override the global definition(s). This mechanism works like the one using global firewall
objects for the Barracuda NG Firewall.
