Section B: Policy configuration
This section explains how to configure policy settings in order to manage
vulnerabilities.
Defining assets for a discovery scan
Use the Discovery policy type on the Policy Management page on the appliance to
configure a policy that defines the parameters used to perform a discovery scan on
a portion of a network.
Before you begin
Before it can perform OS fingerprinting on an asset, your agent must find one
open and one closed port. To find an open and a closed port, the agent scans ports
1–1023 and any other ports specified in the applicable Network Services policy.
About this task
In a discovery task, a range of IP addresses is scanned to locate active network
interfaces, and the type of device associated with each active network interface is
determined through OS identification.
Procedure
1. Click Scan →Policy Management in the navigation pane.
2. Select Discovery from the Policy Types list, and then click Add.
3. Type a name for the scan policy.
4. Type the IP addresses (in dotted-decimal or CIDR notation) of the assets to
discover in the IP range(s) to scan box as in the following examples:
vType an IP address, and then pressENTER.
vType a range of IP addresses, and then pressENTER.
Example: 172.1.1.100-172.1.1.200
vType a combination of both choices above, and then press ENTER.
Note: A red box appears around the IP range(s) to scan box until the data is
validated.
5. If you want to ping each IP address before scanning to exclude unreachable
hosts from the scan, select the Ping hosts in this range, before scanning, to
exclude unreachable hosts check box.
6. If you want to add newly discovered assets to the group where you have
defined the scan, rather than to the Ungrouped Assets group, select the Add
newly discovered assets to group check box.
