network, all users who authenticate successfully on that port are assigned to the DMZ
network.
When using a RADIUS server for authentication, you can assign authenticated users to
specific network segments, by configuring dynamic VLAN assignment on the RADIUS
server. Upon successful authentication, the RADIUS server sends RADIUS option 81
[Tunnel-Private-Group-ID] to the Safe@Office appliance, indicating to which network
segment the user should be assigned. For example, if a member of the Accounting team
connects to a network port and attempts to log in, the Safe@Office appliance relays the
information to the RADIUS server, which replies with RADIUS option 81 and the value
“Accounting”. The appliance then assigns the user’s port to the Accounting network,
granting the user access to all the resources of the Accounting team.
The Safe@Office appliance also enables you to automatically assign users to a
“Quarantine” network when authentication fails. All Quarantine network security and
network rules will apply to those users. For example, you can create security rules
allowing users on the Quarantine network to access the Internet and blocking them from
accessing sensitive company resources. You can also configure Traffic Shaper to grant
members of the Quarantine network a lower amount of bandwidth than authorized users.
You can choose to exclude specific network objects from 802.1x port-based security
enforcement. Excluded network objects will be able to connect to the Safe@Office
appliance's ports and access the network without authenticating. For information on
excluding network objects from 802.1x port-based security enforcement, see Using
Network Objects on page 227.
