Click 'Network Management' > 'Discoveries' to open the scan configuration area

Introduction

Click 'Network Management' > 'Discoveries' to open this interface.

  • The discovery feature lets you scan networks and active directory (AD) servers to identify all devices on the network.
     
  • The scan will identify both managed and unmanaged devices. You can configure EM to alert you if a scan finds new devices.
     
  • You can run simple network scans from a ‘probe device’ situated in the target network. The probe device must be a managed Windows endpoint which has already been added to Endpoint Manager.
     
  • You can scan Active Directory servers either with or without the use of a probe device.
     
  • All discovered devices are shown in 'Network Management' > 'Devices' > 'Discovered Devices':


Notes:

  • All newly discovered devices are 'Unmanaged'. This means you can’t yet control them with Endpoint Manager. You need to install the communication client on the devices to enroll them.
     
  • All discovered devices are placed into a group of your choice. You can then create a client installation package for the group and use Comodo's auto-deployment tool to install it. This will enroll the devices to the endpoint manager.
     
  • You can change the owner and group of these devices after they have been enrolled. Full auto-enrollment of discovered devices is coming in later releases.

Preliminaries

  • Optional – Make sure your probe device is in place. It can be any managed Windows endpoint inside the network that you want to scan. This device will launch the scans you request on the target network. The probe is required for network and SNMP scans but is optional for Active Directory scans.
     
  • Create a new group for discovered devices under the company of your choice:
     
    • Login to Comodo One/ Dragon
       
    • Click 'Application' > 'Endpoint Manager'
       
    • Click 'Devices' > 'Device List' > 'Group Management' > 'Create Group'.
       
    • Name the group, for example, 'Discovered Devices - Company X'.
       
    • Do not add any existing devices to this group. Leave it empty. The group is pure to segment the discovered devices. You can move devices to different groups after they have been enrolled.

Create a discovery scan

There are two types of discovery task:

  • Network -  Scan an IP range using a probe device. The probe must be a managed Windows device connected to the network. You can run a concurrent SNMP scan when you run a network scan.
     
  • Active Directory – Scan an Active Directory domain for devices. You can configure the scan with or without a probe device. If not specified, EM will directly scan the AD server.

Network Discovery Scan

  • Login to Comodo One/ Dragon
     
  • Click 'Application' > 'Endpoint Manager'
     
  • Click 'Network Management' > 'Discoveries'
     
  • Click 'Create Discovery'


 

  • Discovery Name  - Create a label for the discovery task. Ideally, the label should help you identify the target or purpose of the task in the future.
     
  • Select 'by Network'
     
  • Click 'Next' to add probe devices.


 

  • Select Device(s) – Start typing the name of the device you want to use as the probe and select from the suggestions.
     
    • A probe device is a managed Windows endpoint inside the network that you want to scan. The device must already be enrolled to Endpoint Manager and have communication client (CC) 6.32 or higher installed. This device will launch the scans you request on the target network.
       
    • You can also add additional devices for fail-over. The device added first will be used as the probe. If the first device is offline then EM will use the next device for the scan.
       
  • Enable SNMP for discovery – Run a simple network management protocol (SNMP) scan alongside the network scan.
     
    • If enabled, the SNMP scan will run simultaneously with the IP range scan.
       
    • The SNMP results are shown as a separate row in the 'Network Management' > 'Devices' > 'Discovered Devices' interface.
       
    • Community String - This is a passcode sent with each SNMP Get-Request to authenticate access to a router or other device. If the community string is correct, then the device responds with the requested information.
       
  • Run immediately after discovery is created - The discovery scan will start after it is saved.
     
  • Click 'Create'

The discovery task configuration screen opens:


 

  • General - Specify the IP addresses you want to scan. Set the customer and device group to which new devices should be assigned. Choose your probe device.
  • Auto Enrollment - Windows devices only. Set the customer and device group to which you want to assign discovered Windows devices. Complete the instructions in the ‘Auto Enrollment’ tab on the probe and target devices.
     
  • Notifications - Select which events you want to be notified about. Events include when the scan ends, when a new device is found, and when a new IP is found. (Optional)
     
  • Schedule - You can automate the discovery scans by scheduling them to run daily, weekly or monthly. (Optional)
     
  • Discovery Logs - View the results of previous scans run under this task. You can see the date, type and other general details about a scan. Click 'Details' then 'Click Here' to view a list of devices found by the scan.
     
  • Next, click 'Edit' on the right to configure scan targets and options.

General Settings
 


 

  • Discovery name -  This is pre-populated with the label you created in the previous step. Edit the name, if required.
