Creating a New Zone for the PortShield Interface
You may want to create a zone for a PortShield interface that has different attributes to it than
any of the default zones provide. To create a new zone for a PortShield interface, perform the
following:
1. In the Add PortShield Interface window, click on the Zone list box and click on the Create
New Zone option. The management software displays the General Settings dialog box.
2. Type a name in the Name field that will identify the new zone.
3. Click on the Security Type list box and click on a security type option that will classify the
zone as having a certain level of access. The choices are:
–
Trusted - This security type offers the highest level of security, indicating that only
trust, indicating that the least amount of scrutiny is applied to traffic coming from trusted
zones. Trusted security can be thought of as being on the LAN (protected) side of the
device. The LAN zone is always Trusted.
–
Public -This security type offers a higher level of security than an Untrusted zone, but
a lower level of trust than a Trusted zone. Public zones can be thought of as being a
secure area between the LAN (protected) side of the device and the WAN (unprotected)
side. The DMZ, for example, is a Public zone because traffic flows from it to both the
LAN and the WAN.
–
Wireless - This security type applies to the WLAN zone or any zone where the only
interface to the network consists of SonicWALL SonicPoint devices. You typical use
WiFiSec to secure traffic in a wireless zone.
