VMware NSX security tag action

If an endpoint instance in a VMware NSX environment is compromised, this action will assign the configured security tag to the compromised endpoint.

This action is only available when the automation trigger is set to compromised host.

To set up the NSX quarantine action, you need to:

1. Configure a VMware NSX SDN connector
2. Configure an NSX security tag automation stitch
3. Configure FortiAnalyzer logging on the FortiGate

Configure a VMware NSX SDN connector

The FortiGate retrieves security tags from the VMware NSX server through the connector.

To configure a VMware NSX SDN connector in the GUI:

1. Go to Security Fabric > External Connectors.
2. Click Create New.
3. Select VMware NSX.
4. Configure the settings as needed.

   

5. Click OK.

To configure a VMware NSX SDN connector in the CLI:

config system sdn-connector
    edit "nsx"
        set type nsx
        set server "172.18.64.32"
        set username "admin"
        set password xxxxxxxxxxxx
    next
end

Configure an NSX security tag automation stitch

Security tags are retrieved from the VMware NSX server through the NSX SDN connector.

To configure an automation stitch with an NSX security tag in the GUI:

1. Go to Security Fabric > Automation and click Create New.
2. Enter the stitch name (pcui-test).
3. Configure the trigger:
   1. Click Add Trigger.
   2. Click Create and select Compromised Host.
   3. Enter the trigger name (pcui-test).
   4. Click OK.
   5. Select the trigger in the list and click Apply.
4. Configure the VMware NSX Security Tag action:
   1. Click Add Action.
   2. Click Create and select VMware NSX Security Tag.
   3. Enter the following:

      Name	pcui-test_quarantine-nsx
      Specify NSX server(s)	Enable and select the SDN connector
      Security tag	Select an existing tag, or create a new one

      

   4. Click OK.
   5. Select the action in the list and click Apply.
5. Click OK.

To configure an automation stitch with an NSX security tag in the CLI:

1. Create the automation trigger:

   config system automation-trigger
       edit "pcui-test"
       next
   end

2. Create the automation action:

   config system automation-action
       edit "pcui-test_quarantine-nsx"
           set action-type quarantine-nsx
           set security-tag "pcui-tag2"
           set sdn-connector "nsx"
       next
   end

3. Create the automation stitch:

   config system automation-stitch
       edit "pcui-test"
           set trigger "pcui-test"
           config actions
               edit 1
                   set action "pcui-test_quarantine-nsx"
                   set required enable
               next
           end
       next
   end

Configure FortiAnalyzer logging on the FortiGate

The FortiAnalyzer is used to send endpoint compromise notification to the FortiGate.

See Configuring FortiAnalyzer for more information.

To configure FortiAnalyzer logging in the GUI:

1. Go to Security Fabric > Fabric Connectors and double-click the Logging & Analytics card.
2. In the Settings > FortiAnalyzer tab, ensure the Status is Enabled, and configure the settings as needed.

   

3. Click OK.

To configure FortiAnalyzer logging in the CLI:

config log fortianalyzer setting
    set status enable
    set server "172.18.64.234"
    set serial "FL-8HFT000000000"
    set upload-option realtime
    set reliable enable
end

When an endpoint instance is compromised

When an endpoint instance, such as pcui-ubuntu2, in the VMware NSX environment is compromised, the automation stitch is triggered. The FortiGate then assigns the configured security tag, pcui-tag2 in this example, to the compromised NSX endpoint instance.
