ZTNA IP MAC based access control example

In this example, firewall policies are configured that use ZTNA tags to control access between on-net devices and an internal web server. This mode does not require the use of the access proxy, and only uses ZTNA tags for access control. Traffic is passed when the FortiClient endpoint meets two conditions.

It is tagged with the Domain-Users ZTNA tag, identifying the device as logged on to the Domain.
It has the High importance classification tag indicating the device is High importance and low risk.

Traffic is denied when the FortiClient endpoint is tagged with Malicious-File-Detected.

This example assumes that the FortiGate EMS fabric connector is already successfully connected.

To configure ZTNA in the GUI, go to System > Feature Visibility and enable Zero Trust Network Access.

To configure Zero Trust tagging rules on the FortiClient EMS:

Log in to the FortiClient EMS.
Go to Zero Trust Tags > Zero Trust Tagging Rules, and click Add.
In the Name field, enter Malicious-File-Detected.
In the Tag Endpoint As dropdown list, select Malicious-File-Detected.
Click Add Rule then configure the rule:
1. For OS, select Windows.
2. From the Rule Type dropdown list, select File and click the + button.
3. Enter a file name, such as C:\virus.txt.
4. Click Save.
Click Save.
Click Add again to add another rule.
In the Name field, enter Domain-Users.
In the Tag Endpoint As dropdown list, enter Domain-Users and press Enter.
Click Add Rule, then configure the rule:
1. For OS, select Windows.
2. From the Rule Type dropdown list, select User in AD Group.
3. For AD Group, select the Domain-Users AD group.
4. Click Save.

To configure a classification tag on the FortiClient EMS:

Go to Endpoint > All Endpoints.
Select the WIN10-01 computer that will be granted access. This computer should be already registered to FortiClient EMS.
In the Summary tab, under Classification Tags, click Add and then set to High Importance.
Go to Administration > Fabric Devices.
Select the connecting FortiGate, then click Edit.
Under Tag Types Being Shared, add Classification Tags.
Click Save.

To configure a firewall policy with IP/MAC based access control to deny traffic in the GUI:

Go to Policy & Objects > Firewall Policy and click Create New.
Set Name to block-internal-malicious-access.
Set Type to Standard.
Set Incoming Interface to port1.
Set Outgoing Interface to port2.
Set Source to all.
Set IP/MAC Based Access Control to the Malicious-File-Detected tag.
Set Destination to the address of the Web server. If no address is created, create a new address object for 10.88.0.3/32.
Set Service to ALL.
Set Action to DENY.
Enable Log Violation Traffic.
Configuring the remaining settings as needed.
Click OK.

To configure a firewall policy with IP/MAC based access control to allow access in the GUI:

Go to Policy & Objects > Firewall Policy and click Create New.
Set Name to allow-internal-access.
Set Type to Standard.
Set Incoming Interface to port1.
Set Outgoing Interface to port2.
Set Source to all.
Set IP/MAC Based Access Control to the Domain-Users ZTNA IP tag.
Set Logical And With Secondary Tags to Specify. This option allows for a second group of tags to be used with a logical And operator.
Set Secondary Tags as the High Class IP tag.
Set Destination to the address of the Web server.
Set Service to ALL.
Set Action to ACCEPT.
Enable Log Allowed Traffic and set it to All Sessions.
Configuring the remaining settings as needed.
Click OK.

To configure firewall policies with IP/MAC based access control to block and allow access in the CLI:

config firewall policy
    edit 10
        set name "block-internal-malicious-access"
        set srcintf "port1"
        set dstintf "port2"
        set ztna-status enable
        set srcaddr "all"
        set dstaddr "Webserver"
        set ztna-ems-tag "EMS1_ZTNA_Malicious-File-Detected"
        set schedule "always"
        set service "ALL"
        set logtraffic all
    next
    edit 12
        set name "allow-internal-access"
        set srcintf "port1"
        set dstintf "port2"
        set action accept
        set ztna-status enable
        set srcaddr "all"
        set dstaddr "Webserver"
        set ztna-ems-tag "EMS1_ZTNA_Domain-Users"
        set ztna-ems-tag-secondary "EMS1_CLASS_High"
        set schedule "always"
        set service "ALL"
        set logtraffic all
    next
end

When multiple tags are selected with set ztna-ems-tag <tags>, matching occurs using a logical OR operator. Therefore any single tag that match will return true.

The set ztna-tags-match-logic {and | or} option cannot be used to change the logical operator. This option is applied by wad to tags selected for ZTNA proxy-policy.

The set ztna-ems-tag-secondary <tags> option by default allows a second group of tags to be specified. This group and the primary group are joined by the logical and operator.

Testing the access to the web server from the on-net client endpoint

Access allowed:

On the WIN10-01 PC, open FortiClient.
On the Zero Trust Telemetry tab, make sure that you are connected to the EMS server.
Open a browser and enter the address of the server.
The FortiGate matches your security posture by verifying your ZTNA tags and matching the corresponding allow-internal-access firewall policy, and you are allowed access to the web server.

Access denied:

On the WIN10-01 PC, trigger the Zero Trust Tagging Rule by creating the file in C:\virus.txt.
Open a browser and enter the address of the server.
FortiGate checks your security posture. Because EMS has tagged the PC with the Malicious-File-Detected tag, it matches the block-internal-malicious-access firewall policy.
You are denied access to the web server.

ZTNA IP MAC based access control example

It is tagged with the Domain-Users ZTNA tag, identifying the device as logged on to the Domain.
It has the High importance classification tag indicating the device is High importance and low risk.

Traffic is denied when the FortiClient endpoint is tagged with Malicious-File-Detected.

This example assumes that the FortiGate EMS fabric connector is already successfully connected.

To configure ZTNA in the GUI, go to System > Feature Visibility and enable Zero Trust Network Access.

To configure Zero Trust tagging rules on the FortiClient EMS:

Log in to the FortiClient EMS.
Go to Zero Trust Tags > Zero Trust Tagging Rules, and click Add.
In the Name field, enter Malicious-File-Detected.
In the Tag Endpoint As dropdown list, select Malicious-File-Detected.
Click Add Rule then configure the rule:
1. For OS, select Windows.
2. From the Rule Type dropdown list, select File and click the + button.
3. Enter a file name, such as C:\virus.txt.
4. Click Save.
Click Save.
Click Add again to add another rule.
In the Name field, enter Domain-Users.
In the Tag Endpoint As dropdown list, enter Domain-Users and press Enter.
Click Add Rule, then configure the rule:
1. For OS, select Windows.
2. From the Rule Type dropdown list, select User in AD Group.
3. For AD Group, select the Domain-Users AD group.
4. Click Save.

To configure a classification tag on the FortiClient EMS:

Go to Endpoint > All Endpoints.
Select the WIN10-01 computer that will be granted access. This computer should be already registered to FortiClient EMS.
In the Summary tab, under Classification Tags, click Add and then set to High Importance.
Go to Administration > Fabric Devices.
Select the connecting FortiGate, then click Edit.
Under Tag Types Being Shared, add Classification Tags.
Click Save.

To configure a firewall policy with IP/MAC based access control to deny traffic in the GUI:

Go to Policy & Objects > Firewall Policy and click Create New.
Set Name to block-internal-malicious-access.
Set Type to Standard.
Set Incoming Interface to port1.
Set Outgoing Interface to port2.
Set Source to all.
Set IP/MAC Based Access Control to the Malicious-File-Detected tag.
Set Destination to the address of the Web server. If no address is created, create a new address object for 10.88.0.3/32.
Set Service to ALL.
Set Action to DENY.
Enable Log Violation Traffic.
Configuring the remaining settings as needed.
Click OK.

To configure a firewall policy with IP/MAC based access control to allow access in the GUI:

Go to Policy & Objects > Firewall Policy and click Create New.
Set Name to allow-internal-access.
Set Type to Standard.
Set Incoming Interface to port1.
Set Outgoing Interface to port2.
Set Source to all.
Set IP/MAC Based Access Control to the Domain-Users ZTNA IP tag.
Set Logical And With Secondary Tags to Specify. This option allows for a second group of tags to be used with a logical And operator.
Set Secondary Tags as the High Class IP tag.
Set Destination to the address of the Web server.
Set Service to ALL.
Set Action to ACCEPT.
Enable Log Allowed Traffic and set it to All Sessions.
Configuring the remaining settings as needed.
Click OK.

To configure firewall policies with IP/MAC based access control to block and allow access in the CLI:

config firewall policy
    edit 10
        set name "block-internal-malicious-access"
        set srcintf "port1"
        set dstintf "port2"
        set ztna-status enable
        set srcaddr "all"
        set dstaddr "Webserver"
        set ztna-ems-tag "EMS1_ZTNA_Malicious-File-Detected"
        set schedule "always"
        set service "ALL"
        set logtraffic all
    next
    edit 12
        set name "allow-internal-access"
        set srcintf "port1"
        set dstintf "port2"
        set action accept
        set ztna-status enable
        set srcaddr "all"
        set dstaddr "Webserver"
        set ztna-ems-tag "EMS1_ZTNA_Domain-Users"
        set ztna-ems-tag-secondary "EMS1_CLASS_High"
        set schedule "always"
        set service "ALL"
        set logtraffic all
    next
end

When multiple tags are selected with set ztna-ems-tag <tags>, matching occurs using a logical OR operator. Therefore any single tag that match will return true.

The set ztna-tags-match-logic {and | or} option cannot be used to change the logical operator. This option is applied by wad to tags selected for ZTNA proxy-policy.

The set ztna-ems-tag-secondary <tags> option by default allows a second group of tags to be specified. This group and the primary group are joined by the logical and operator.

Testing the access to the web server from the on-net client endpoint

Access allowed:

On the WIN10-01 PC, open FortiClient.
On the Zero Trust Telemetry tab, make sure that you are connected to the EMS server.
Open a browser and enter the address of the server.
The FortiGate matches your security posture by verifying your ZTNA tags and matching the corresponding allow-internal-access firewall policy, and you are allowed access to the web server.

Access denied:

On the WIN10-01 PC, trigger the Zero Trust Tagging Rule by creating the file in C:\virus.txt.
Open a browser and enter the address of the server.
FortiGate checks your security posture. Because EMS has tagged the PC with the Malicious-File-Detected tag, it matches the block-internal-malicious-access firewall policy.
You are denied access to the web server.
