Establish groups of monitored networks using IP addresses to allow Deep Discovery Inspector to determine whether attacks originate from within or outside the network.

  1. Click Add.
  2. Specify a group name.
  3. Specify an IP address range in the text box (up to 1,000 IP address ranges).

    Deep Discovery Inspector comes with a monitored network called Default, which contains the following IP address blocks reserved by the Internet Assigned Numbers Authority (IANA) for private networks:

    • 10.0.0.0 - 10.255.255.255

    • 172.16.0.0 - 172.31.255.255

    • 192.168.0.0 - 192.168.255.255

    Note:

    • If you did not remove Default, you do not need to specify these IP address blocks when adding a new monitored network.

    • Use a dash to specify an IP address range.

      Example: 192.168.1.0-192.168.1.255.

    • Use a slash to specify the subnet mask for IP addresses.

      Example: 192.168.1.0/255.255.255.0 or 192.168.1.0/24.

    • Up to three layers of sub-groups can be added.

  4. Select the network zone of network group:

    • Trusted: This is a secure network

    • Untrusted: There is a degree of doubt about the security of the network.

  5. Click Add.
  6. Click Finish.
