Threat Defense Deployment with CDO

Note

Version 7.4 is the final release for the Firepower 2100.

Is This Chapter for You?

To see all available applications and managers, see Which Application and Manager is Right for You?. This chapter applies to the threat defense using Cisco Defense Orchestrator (CDO)'s cloud-delivered Firewall Management Center.

Note

CDO supports threat defense 7.2 and later.

About the Firewall

The hardware can run either threat defense software or ASA software. Switching between threat defense and ASA requires you to reimage the device. You should also reimage if you need a different software version than is currently installed. See Cisco Secure Firewall ASA and Secure Firewall Threat Defense Reimage Guide.

The firewall runs an underlying operating system called the Secure Firewall eXtensible Operating System (FXOS). The firewall does not support the FXOS Secure Firewall chassis manager; only a limited CLI is supported for troubleshooting purposes. See the Cisco FXOS Troubleshooting Guide for the Firepower 1000/2100 and Secure Firewall 3100/4200 with Firepower Threat Defense for more information.

Privacy Collection Statement—The firewall does not require or actively collect personally identifiable information. However, you can use personally identifiable information in the configuration, for example for usernames. In this case, an administrator might be able to see this information when working with the configuration or when using SNMP.

About Threat Defense Management by CDO

About the Cloud-delivered Firewall Management Center

The cloud-delivered Firewall Management Center offers many of the same functions as an on-premises management center and has the same look and feel. When you use CDO as the primary manager, you can use an on-prem management center for analytics only. The on-prem management center does not support policy configuration or upgrading.

CDO Onboarding Methods

Use one of the following methods to onboard a device.

Zero-Touch Provisioning

Send the threat defense to the remote branch office. Do not configure anything on the device, because zero-touch provisioning may not work with pre-configured devices.

Note

You can preregister the threat defense on CDO using the threat defense serial number before sending the device to the branch office.

At the branch office, cable and power on the threat defense.
Finish onboarding the threat defense using CDO.

Manual Provisioning

Use the manual onboarding wizard and CLI registration if you need to perform any pre-configuration or if you are using a manager interface that zero-touch provisioning does not support.

Threat Defense Manager Access Interface

This guide covers outside interface access because it is the most likely scenario for remote branch offices. Although manager access occurs on the outside interface, the dedicated Management interface is still relevant. The Management interface is a special interface configured separately from the threat defense data interfaces, and it has its own network settings.

The Management interface network settings are still used even though you are enabling manager access on a data interface.
All management traffic continues to be sourced from or destined to the Management interface.
When you enable manager access on a data interface, the threat defense forwards incoming management traffic over the backplane to the Management interface.
For outgoing management traffic, the Management interface forwards the traffic over the backplane to the data interface.

Manager Access Requirements

Manager access from a data interface has the following limitations:

You can only enable manager access on a physical, data interface. You cannot use a subinterface or EtherChannel, nor can you create a subinterface on the manager access interface. You can also use the management center to enable manager access on a single secondary interface for redundancy.
This interface cannot be management-only.
Routed firewall mode only, using a routed interface.
PPPoE is not supported. If your ISP requires PPPoE, you will have to put a router with PPPoE support between the threat defense and the WAN modem.
The interface must be in the global VRF only.
SSH is not enabled by default for data interfaces, so you will have to enable SSH later using the management center. Because the Management interface gateway will be changed to be the data interfaces, you also cannot SSH to the Management interface from a remote network unless you add a static route for the Management interface using the configure network static-routes command.

High Availability Requirements

When using a data interface with device high availability, see the following requirements.

Use the same data interface on both devices for manager access.
Redundant manager access data interface is not supported.
You cannot use DHCP; only a static IP address is supported. Features that rely on DHCP cannot be used, including DDNS and zero-touch provisioning.
Have different static IP addresses in the same subnet.
Use either IPv4 or IPv6; you cannot set both.
Use the same manager configuration (configure manager add command) to ensure that the connectivity is the same.
You cannot use the data interface as the failover or state link.

Central Administrator Pre-Configuration

This section describes how to obtain feature licenses for your firewall; how to install a new software version before you deploy; and how to log into CDO.

Obtain Licenses

All licenses are supplied to the threat defense by CDO. You can optionally purchase the following feature licenses:

Essentials—(Required) Essentials license.
IPS—Security Intelligence and Next-Generation IPS
Malware Defense—Malware defense
URL Filtering—URL Filtering
Cisco Secure Client—Secure Client Advantage, Secure Client Premier, or Secure Client VPN Only

For a more detailed overview on Cisco Licensing, go to cisco.com/go/licensingguide

Before you begin

Have an account on the Smart Software Manager.

If you do not yet have an account, click the link to set up a new account. The Smart Software Manager lets you create an account for your organization.
Your Smart Software Licensing account must qualify for the Strong Encryption (3DES/AES) license to use some features (enabled using the export-compliance flag).

Procedure

Step 1

Make sure your Smart Licensing account contains the available licenses you need.

When you bought your device from Cisco or a reseller, your licenses should have been linked to your Smart Software License account. However, if you need to add licenses yourself, use the Search All field on the Cisco Commerce Workspace.

Choose Products & Services from the results.

Search for the following license PIDs:

Note

If a PID is not found, you can add the PID manually to your order.

IPS, Malware Defense, and URL license combination:
- L-FPR2110T-TMC=
- L-FPR2120T-TMC=
- L-FPR2130T-TMC=
- L-FPR2140T-TMC=
When you add one of the above PIDs to your order, you can then choose a term-based subscription corresponding with one of the following PIDs:
- L-FPR2110T-TMC-1Y
- L-FPR2110T-TMC-3Y
- L-FPR2110T-TMC-5Y
- L-FPR2120T-TMC-1Y
- L-FPR2120T-TMC-3Y
- L-FPR2120T-TMC-5Y
- L-FPR2130T-TMC-1Y
- L-FPR2130T-TMC-3Y
- L-FPR2130T-TMC-5Y
- L-FPR2140T-TMC-1Y
- L-FPR2140T-TMC-3Y
- L-FPR2140T-TMC-5Y
Cisco Secure Client—See the Cisco Secure Client Ordering Guide.

Step 2

If you have not already done so, register CDO with the Smart Software Manager.

Registering requires you to generate a registration token in the Smart Software Manager. See the CDO documentation for detailed instructions.

(Optional) Check the Software and Install a New Version

To check the software version and, if necessary, install a different version, perform these steps. We recommend that you install your target version before you configure the firewall. Alternatively, you can perform an upgrade after you are up and running, but upgrading, which preserves your configuration, may take longer than using this procedure.

What Version Should I Run?

Cisco recommends running a Gold Star release indicated by a gold star next to the release number on the software download page. You can also refer to the release strategy described in https://www.cisco.com/c/en/us/products/collateral/security/firewalls/bulletin-c25-743178.html; for example, this bulletin describes short-term release numbering (with the latest features), long-term release numbering (maintenance releases and patches for a longer period of time), or extra long-term release numbering (maintenance releases and patches for the longest period of time, for government certification).

Procedure

Step 1

Power on the firewall and connect to the console port. See Power on the Firewall and Access the Threat Defense and FXOS CLI for more information.

You connect to the FXOS CLI. The first time you log in, you are prompted to change the password. This password is also used for the threat defense login for SSH.

Note

If the password was already changed, and you do not know it, you must perform a factory reset to reset the password to the default. See the FXOS troubleshooting guide for the factory reset procedure.

Example:


firepower login: admin
Password: Admin123
Successful login attempts for user 'admin' : 1

[...]

Hello admin. You must change your password.
Enter new password: ********
Confirm new password: ********
Your password was updated successfully.

[...]

firepower#

Step 2

At the FXOS CLI, show the running version.

scope ssa

show app-instance

Example:


Firepower# scope ssa
Firepower /ssa # show app-instance

Application Name     Slot ID    Admin State     Operational State    Running Version Startup Version Cluster Oper State
-------------------- ---------- --------------- -------------------- --------------- --------------- ------------------
ftd                  1          Enabled         Online               7.6.0.65        7.6.0.65        Not Applicable

Step 3

If you want to install a new version, perform these steps.

If you need to set a static IP address for the Management interface, see Perform Initial Configuration Using the CLI. By default, the Management interface uses DHCP.

You will need to download the new image from a server accessible from the Management interface.
Perform the reimage procedure in the FXOS troubleshooting guide.

After the firewall reboots, you connect to the FXOS CLI again.
At the FXOS CLI, you are prompted to set the admin password again.

For zero-touch provisioning, when you onboard the device, for the Password Reset area, be sure to choose No... because you already set the password.
Shut down the device. See Power Off the Device at the CLI.

Log Into CDO

For details on creating a CDO tenant and logging in, see the CDO doucmentation: https://docs.defenseorchestrator.com.

Deploy the Firewall With Low-Touch Provisioning

After you receive the threat defense from central headquarters, you only need to cable and power on the firewall so that it has internet access from the outside interface. The central administrator can then complete the configuration.

Provide the Firewall Serial Number to the Central Administrator

Before you rack the firewall or discard the shipping box, record the serial number so you can coordinate with the central adminstrator.

Procedure

Step 1

Unpack the chassis and chassis components.

Take inventory of your firewall and packaging before you connect any cables or power on the firewall. You should also familiarize yourself with the chassis layout, components, and LEDs.

Step 2

Record the firewall's serial number.

The serial number of the firewall can be found on the shipping box. It can also be found on a sticker on a pull-out tab on the front of the firewall.

Step 3

Send the firewall serial number to the CDO network administrator at your IT department/central headquarters.

Your network administrator needs your firewall serial number to facilitate low-touch provisioning, connect to the firewall, and configure it remotely.

Communicate with the CDO administrator to develop an onboarding timeline.

Cable the Firewall

This topic describes how to connect the Firepower 2100 to your network so that it can be managed by CDO.

If you received a firewall at your branch office, and your job is to plug it in to your network, watch this video. The video describes your firewall and the LED sequences on the firewall that indicate the firewall's status. If you need to, you'll be able to confirm the firewall's status with your IT department just by looking at the LEDs.

Low-touch provisioning supports connecting to CDO on Ethernet 1/1 (outside).

Procedure

Step 1	Install the chassis. See the hardware installation guide.
Step 2	Connect the network cable from the Ethernet 1/1 interface to your wide area network (WAN) modem. Your WAN modem is your branch's connection to the internet and will be your firewall's route to the internet as well.
Step 3	Connect the inside interface (for example, Ethernet 1/2) to your inside switch or router. You can choose any interface for inside.
Step 4	Connect other networks to the remaining interfaces.
Step 5	(Optional) Connect the management computer to the console port. At the branch office, the console connection is not required for everyday use; however, it may be required for troubleshooting purposes.

Power On the Firewall

The power switch is located to the left of power supply module 1 on the rear of the chassis. It is a toggle switch that controls power to the system. If the power switch is in standby position, only the 3.3-V standby power is enabled from the power supply module and the 12-V main power is OFF. When the switch is in the ON position, the 12-V main power is turned on and the system boots.

Note

The first time you boot up the threat defense, initialization can take approximately 15 to 30 minutes.

Before you begin

It's important that you provide reliable power for your device (for example, using an uninterruptable power supply (UPS)). Loss of power without first shutting down can cause serious file system damage. There are many processes running in the background all the time, and losing power does not allow the graceful shutdown of your system.

Procedure

Step 1	Attach the power cord to the device and connect it to an electrical outlet.
Step 2	Press the power switch on the back of the device.
Step 3	Check the PWR LED on the front of the device; if it is solid green, the device is powered on.
Step 4	Observe the SYS LED on the front the device; when the device is booting correctly, the SYS LED flashes fast green. If there is a problem, the SYS LED flashes fast amber. If this happens, call your IT department.
Step 5	Observe the SYS LED on the front; when the device connects to the Cisco cloud, the SYS LED slowly flashes green. If there is a problem, the SYS LED flashes amber and green, and the device did not reach the Cisco Cloud. If this happens, make sure that your network cable is connected to the Ethernet 1/1 interface and to your WAN modem. If after adjusting the network cable, the device does not reach the Cisco cloud after about 10 more minutes, call your IT department.

What to do next

Communicate with your IT department to confirm your onboarding timeline and activities. You should have a communication plan in place with the CDO administrator at your central headquarters.
After you complete this task, your CDO administrator will be able to configure and manage the Firepower device remotely. You're done.

Onboard a Device with Zero-Touch Provisioning

Onboard the threat defense using zero-touch provisioning and the device serial number.

Procedure

Step 1

In the CDO navigation pane, click Inventory, then click the blue plus button ( plus sign ) to Onboard a device.

Step 2

Select the FTD tile.

Step 3

Under Management Mode, be sure FTD is selected.

Step 7

In Password Reset, click Yes.... Enter a new password and confirm the new password for the device, then click Next.

For low-touch provisioning, the device must be brand new or has been reimaged.

Note

If you did log into the device and reset the password, and you did not change the configuration in a way that would disable low-touch provisioning, then you should choose the No... option. There are a number of configurations that disable low-touch provisioning, so we don't recommend logging into the device unless you need to, for example, to perform a reimage.

Step 8

For the Policy Assignment, use the drop-down menu to choose an access control policy for the device. If you have no policies configured, choose the Default Access Control Policy.

Step 9

For the Subscription License, check each of the feature licenses you want to enable. Click Next.

Step 10

(Optional) Add labels to your device to help sort and filter the Inventory page. Enter a label and select the blue plus button ( plus sign ). Labels are applied to the device after it's onboarded to CDO.

From the Inventory page, select the device you just onboarded and select any of the option listed under the Management pane located to the right.

Deploy the Firewall With the Onboarding Wizard

This section describes how to configure the firewall for onboarding using the CDO onboarding wizard.

Cable the Firewall

This topic describes how to connect the Firepower 2100 to your network so that it can be managed by CDO.

You can connect to CDO on any data interface or the Management interface, depending on which interface you set for manager access during initial setup. This guide shows the outside interface.

Procedure

Step 1	Install the chassis. See the hardware installation guide.
Step 2	Connect the outside interface (for example, Ethernet 1/1) to your outside router.
Step 3	Connect the inside interface (for example, Ethernet 1/2) to your inside switch or router.
Step 4	Connect other networks to the remaining interfaces.
Step 5	Connect the management computer to the console port or the Ethernet 1/2 interface. If you perform intial setup using the CLI, you will need to connect to the console port. The console port may also be required for troubleshooting purposes. If you perform initial setup using the device manager, connect to the Ethernet 1/2 interface.

Power on the Firewall

The first time you boot up the threat defense, initialization can take approximately 15 to 30 minutes.

Before you begin

Procedure

Step 1

Attach the power cord to the device and connect it to an electrical outlet.

Step 2

Press the power switch on the back of the device.

Step 3

Check the PWR LED on the front of the device; if it is solid green, the device is powered on.

Step 4

Check the SYS LED on the front of the device; after it is solid green, the system has passed power-on diagnostics.

Note

Before you move the power switch to the OFF position, use the shutdown commands so that the system can perform a graceful shutdown. This may take several minutes to complete. After the graceful shutdown is complete, the console displays It is safe to power off now. The front panel blue locator beacon LED lights up indicating the system is ready to be powered off. You can now move the switch to the OFF position. The front panel PWR LED flashes momentarily and turns off. Do not remove the power until the PWR LED is completely off.

See the FXOS Configuration Guide for more information on using the shutdown commands.

Step 10	(Optional) Add labels to your device to help sort and filter the Inventory page. Enter a label and select the blue plus button (). Labels are applied to the device after it's onboarded to CDO. Figure 20. Done

What to do next

From the Inventory page, select the device you just onboarded and select any of the option listed under the Management pane located to the right.

Perform Initial Configuration

Perfom initial configuration of the threat defense using the CLI or using the device manager.

Perform Initial Configuration Using the CLI

Connect to the threat defense CLI to perform initial setup. When you use the CLI for initial configuration, only the Management interface and manager access interface settings are retained.When you perform initial setup using the device manager, all interface configuration completed in the device manager is retained when you switch to CDO for management, in addition to the Management interface and manager access interface settings. Note that other default configuration settings, such as the access control policy, are not retained.

Procedure

Step 1

Connect to the threat defense CLI on the console port.

The console port connects to the FXOS CLI.

Step 2

The first time you log in to FXOS, you are prompted to change the password. This password is also used for the threat defense login for SSH.

Note

If the password was already changed, and you do not know it, then you must reimage the device to reset the password to the default. See the FXOS troubleshooting guide for the reimage procedure.

Example:


firepower login: admin
Password: Admin123
Successful login attempts for user 'admin' : 1

[...]

Hello admin. You must change your password.
Enter new password: ********
Confirm new password: ********
Your password was updated successfully.

[...]

firepower#

Step 3

Connect to the threat defense CLI.

connect ftd

Example:


firepower# connect ftd
>

Step 4

The first time you log in to the threat defense, you are prompted to accept the End User License Agreement (EULA). You are then presented with the CLI setup script for the Management interface settings.

The Management interface settings are used even though you are enabling manager access on a data interface.

Note

You cannot repeat the CLI setup wizard unless you clear the configuration; for example, by reimaging. However, all of these settings can be changed later at the CLI using configure network commands. See Cisco Secure Firewall Threat Defense Command Reference.

Defaults or previously entered values appear in brackets. To accept previously entered values, press Enter.

See the following guidelines:

Do you want to configure IPv4? and/or Do you want to configure IPv6?—Enter y for at least one of these types of addresses. Although you do not plan to use the Management interface, you must set an IP address, for example, a private address.
Configure IPv4 via DHCP or manually? and/or Configure IPv6 via DHCP, router, or manually?—Choose manual. You cannot configure a data interface for management if the management interface is set to DHCP, because the default route, which must be data-interfaces (see the next bullet), might be overwritten with one received from the DHCP server.
Enter the IPv4 default gateway for the management interface and/or Enter the IPv6 gateway for the management interface—Set the gateway to be data-interfaces. This setting forwards management traffic over the backplane so it can be routed through the manager access data interface.
Manage the device locally?—Enter no to use CDO. A yes answer means you will use the device manager instead.
Configure firewall mode?—Enter routed. Outside manager access is only supported in routed firewall mode.

Example:


You must accept the EULA to continue.
Press <ENTER> to display the EULA:

You can register the sensor to a Firepower Management Center and use the
Firepower Management Center to manage it. Note that registering the sensor
to a Firepower Management Center disables on-sensor Firepower Services
management capabilities.

When registering the sensor to a Firepower Management Center, a unique
alphanumeric registration key is always required.  In most cases, to register
a sensor to a Firepower Management Center, you must provide the hostname or
the IP address along with the registration key.
'configure manager add [hostname | ip address ] [registration key ]'

However, if the sensor and the Firepower Management Center are separated by a
NAT device, you must enter a unique NAT ID, along with the unique registration
key.
'configure manager add DONTRESOLVE [registration key ] [ NAT ID ]'

Later, using the web interface on the Firepower Management Center, you must
use the same registration key and, if necessary, the same NAT ID when you add
this sensor to the Firepower Management Center.
>

Step 5

Configure the outside interface for manager access.

configure network management-data-interface

You are then prompted to configure basic network settings for the outside interface. See the following details for using this command:

The Management interface cannot use DHCP if you want to use a data interface for management. If you did not set the IP address manually during initial setup, you can set it now using the configure network {ipv4 | ipv6} manual command. If you did not already set the Management interface gateway to data-interfaces, this command will set it now.
When you add the threat defense to CDO, CDO discovers and maintains the interface configuration, including the following settings: interface name and IP address, static route to the gateway, DNS servers, and DDNS server. For more information about the DNS server configuration, see below. In CDO, you can later make changes to the manager access interface configuration, but make sure you don't make changes that can prevent the threat defense or CDO from re-establishing the management connection. If the management connection is disrupted, the threat defense includes the configure policy rollback command to restore the previous deployment.
If you configure a DDNS server update URL, the threat defense automatically adds certificates for all of the major CAs from the Cisco Trusted Root CA bundle so that the threat defense can validate the DDNS server certificate for the HTTPS connection. The threat defense supports any DDNS server that uses the DynDNS Remote API specification (https://help.dyn.com/remote-access-api/).
This command sets the data interface DNS server. The Management DNS server that you set with the setup script (or using the configure network dns servers command) is used for management traffic. The data DNS server is used for DDNS (if configured) or for security policies applied to this interface.

On CDO, the data interface DNS servers are configured in the Platform Settings policy that you assign to this threat defense. When you add the threat defense to CDO, the local setting is maintained, and the DNS servers are not added to a Platform Settings policy. However, if you later assign a Platform Settings policy to the threat defense that includes a DNS configuration, then that configuration will overwrite the local setting. We suggest that you actively configure the DNS Platform Settings to match this setting to bring CDO and the threat defense into sync.

Also, local DNS servers are only retained by CDO if the DNS servers were discovered at initial registration. For example, if you registered the device using the Management interface, but then later configure a data interface using the configure network management-data-interface command, then you must manually configure all of these settings in CDO, including the DNS servers, to match the threat defense configuration.
You can change the management interface after you register the threat defense to CDO, to either the Management interface or another data interface.
The FQDN that you set in the setup wizard will be used for this interface.
You can clear the entire device configuration as part of the command; you might use this option in a recovery scenario, but we do not suggest you use it for initial setup or normal operation.
To disable data managemement, enter the configure network management-data-interface disable command.

Step 6

Identify the CDO that will manage this threat defense using the configure manager add command that CDO generated. See Onboard a Device with the Onboarding Wizard to generate the command.

Example:


> configure manager add account1.app.us.cdo.cisco.com KPOOP0rgWzaHrnj1V5ha2q5Rf8pKFX9E Lzm1HOynhVUWhXYWz2swmkj2ZWsN3Lb account1.app.us.cdo.cisco.com
Manager successfully configured.

Perform Initial Configuration Using the Device Manager

When you use the device manager for initial setup, the following interfaces are preconfigured in addition to the Management interface and manager access settings:

Ethernet 1/1—"outside", IP address from DHCP, IPv6 autoconfiguration
Ethernet 1/2— "inside", 192.168.95.1/24
Default route—Obtained through DHCP on the outside interface

Note that other settings, such as the DHCP server on inside, access control policy, or security zones, are not configured.

If you perform additional interface-specific configuration within device manager before onboarding to CDO, then that configuration is preserved.

When you use the CLI, only the Management interface and manager access settings are retained (for example, the default inside interface configuration is not retained).

Procedure

Step 1	Connect your management computer to the Ethernet1/2 interface.
Step 2	Log in to the device manager. Enter the following URL in your browser: https://192.168.95.1 Log in with the username admin, and the default password Admin123. You are prompted to read and accept the End User License Agreement and change the admin password.
Step 3	Use the setup wizard when you first log into the device manager to complete the initial configuration. You can optionally skip the setup wizard by clicking Skip device setup at the bottom of the page. After you complete the setup wizard, in addition to the default configuraton for the inside interface (Ethernet1/2), you will have configuration for an outside (Ethernet1/1) interface that will be maintained when you switch to CDO management. Configure the following options for the outside and management interfaces and click Next. Outside Interface Address—This interface is typically the internet gateway, and might be used as your manager access interface. You cannot select an alternative outside interface during initial device setup. The first data interface is the default outside interface. If you want to use a different interface from outside (or inside) for manager access, you will have to configure it manually after completing the setup wizard. Configure IPv4—The IPv4 address for the outside interface. You can use DHCP or manually enter a static IP address, subnet mask, and gateway. You can also select Off to not configure an IPv4 address. You cannot configure PPPoE using the setup wizard. PPPoE may be required if the interface is connected to a DSL modem, cable modem, or other connection to your ISP, and your ISP uses PPPoE to provide your IP address. You can configure PPPoE after you complete the wizard. Configure IPv6—The IPv6 address for the outside interface. You can use DHCP or manually enter a static IP address, prefix, and gateway. You can also select Off to not configure an IPv6 address. Management Interface You will not see Management Interface settings if you performed intial setup at the CLI. The Management interface settings are used even though you are enabling the manager access on a data interface. For example, the management traffic that is routed over the backplane through the data interface will resolve FQDNs using the Management interface DNS servers, and not the data interface DNS servers. DNS Servers—The DNS server for the system's management address. Enter one or more addresses of DNS servers for name resolution. The default is the OpenDNS public DNS servers. If you edit the fields and want to return to the default, click Use OpenDNS to reload the appropriate IP addresses into the fields. Firewall Hostname—The hostname for the system's management address. Configure the Time Setting (NTP) and click Next. Time Zone—Select the time zone for the system. NTP Time Server—Select whether to use the default NTP servers or to manually enter the addresses of your NTP servers. You can add multiple servers to provide backups. Select Start 90 day evaluation period without registration. Do not register the threat defense with the Smart Software Manager; all licensing is performed in CDO. Click Finish. You are prompted to choose Cloud Management or Standalone. For the CDO cloud-delivered management center, choose Standalone, and then Got It. The Cloud Management option is for legacy CDO/FDM functionality.
Step 4	(Might be required) Configure the Management interface. See the Management interface on Device > Interfaces. The Management interface must have the gateway set to data interfaces. By default, the Management interface receives an IP address and gateway from DHCP. If you do not receive a gateway from DHCP (for example, you did not connect this interface to a network), then the gateway will default to data interfaces, and you do not need to configure anything. If you did receive a gateway from DHCP, then you need to instead configure this interface with a static IP address and set the gateway to data interfaces.
Step 5	If you want to configure additional interfaces, including an interface other than outside or inside that you want to use for the manager access, choose Device, and then click the link in the Interfaces summary. See Configure the Firewall in the Device Manager for more information about configuring interfaces in the device manager. Other device manager configuration will not be retained when you register the device to CDO.
Step 6	Choose Device > System Settings > Central Management, and click Proceed to set up the management center management.
Step 7	Configure the Management Center/CDO Details. Figure 21. Management Center/CDO Details For Do you know the Management Center/CDO hostname or IP address, click Yes. CDO generates the configure manager add command. See Onboard a Device with the Onboarding Wizard to generate the command. configure manager add `cdo_hostname` `registration_key` `nat_id` `display_name` Example: Figure 22. configure manager add command components Copy the `cdo_hostname` , `registration_key` , and `nat_id` parts of the command into the Management Center/CDO Hostname/IP Address, Management Center/CDO Registration Key, and NAT ID fields.
Step 8	Configure the Connectivity Configuration. Specify the FTD Hostname. This FQDN will be used for the outside interface, or whichever interface you choose for the Management Center/CDO Access Interface. Specify the DNS Server Group. Choose an existing group, or create a new one. The default DNS group is called CiscoUmbrellaDNSServerGroup, which includes the OpenDNS servers. This setting sets the data interface DNS server. The Management DNS server that you set with the setup wizard is used for management traffic. The data DNS server is used for DDNS (if configured) or for security policies applied to this interface. You are likley to choose the same DNS server group that you used for Management, because both management and data traffic reach the DNS server through the outside interface. On CDO, the data interface DNS servers are configured in the Platform Settings policy that you assign to this threat defense. When you add the threat defense to CDO, the local setting is maintained, and the DNS servers are not added to a Platform Settings policy. However, if you later assign a Platform Settings policy to the threat defense that includes a DNS configuration, then that configuration will overwrite the local setting. We suggest that you actively configure the DNS Platform Settings to match this setting to bring CDO and the threat defense into sync. Also, local DNS servers are only retained by CDO if the DNS servers were discovered at initial registration. For the Management Center/CDO Access Interface, choose outside. You can choose any configured interface, but this guide assumes you are using outside.
Step 9	If you chose a different data interface from outside, then add a default route. You will see a message telling you to check that you have a default route through the interface. If you chose outside, you already configured this route as part of the setup wizard. If you chose a different interface, then you need to manually configure a default route before you connect to CDO. See Configure the Firewall in the Device Manager for more information about configuring static routes in the device manager.
Step 10	Click Add a Dynamic DNS (DDNS) method. DDNS ensures CDO can reach the threat defense at its Fully-Qualified Domain Name (FQDN) if the threat defense's IP address changes. See Device > System Settings > DDNS Service to configure DDNS. If you configure DDNS before you add the threat defense to CDO, the threat defense automatically adds certificates for all of the major CAs from the Cisco Trusted Root CA bundle so that the threat defense can validate the DDNS server certificate for the HTTPS connection. The threat defense supports any DDNS server that uses the DynDNS Remote API specification (https://help.dyn.com/remote-access-api/).
Step 11	Click Connect. The Registration Status dialog box shows the current status of the switch to CDO. After the Saving Management Center/CDO Registration Settings step, go to CDO, and add the firewall. If you want to cancel the switch to CDO, click Cancel Registration. Otherwise, do not close the device manager browser window until after the Saving Management Center/CDO Registration Settings step. If you do, the process will be paused, and will only resume when you reconnect to the device manager. If you remain connected to the device manager after the Saving Management Center/CDO Registration Settings step, you will eventually see the Successful Connection with Management Center or CDO dialog box, after which you will be disconnected from the device manager. Figure 23. Successful Connection

Configure a Basic Security Policy

This section describes how to configure a basic security policy with the following settings:

Inside and outside interfaces—Assign a static IP address to the inside interface. You configured basic settings for the outside interface as part of the manager access setup, but you still need to assign it to a security zone.
DHCP server—Use a DHCP server on the inside interface for clients.
NAT—Use interface PAT on the outside interface.
Access control—Allow traffic from inside to outside.
SSH—Enable SSH on the manager access interface.

Configure Interfaces

When you use zero-touch provisioning or the device manager for initial setup, the following interfaces are preconfigured:

Ethernet 1/1—"outside", IP address from DHCP, IPv6 autoconfiguration
Ethernet 1/2— "inside", 192.168.95.1/24
Default route—Obtained through DHCP on the outside interface

If you performed additional interface-specific configuration within device manager before registering with the management center, then that configuration is preserved.

In any case, you need to perform additional interface configuration after you register the device. Enable the threat defense interfaces, assign them to security zones, and set the IP addresses. .

The following example configures a routed mode inside interface with a static address and a routed mode outside interface using DHCP.

Procedure

Step 1	Choose Devices > Device Management, and click Edit () for the firewall.
Step 2	Click Interfaces. Figure 24. Interfaces
Step 3	Click Edit () for the interface that you want to use for inside. The General tab appears. Figure 25. General Tab Enter a Name up to 48 characters in length. For example, name the interface inside. Check the Enabled check box. Leave the Mode set to None. From the Security Zone drop-down list, choose an existing inside security zone or add a new one by clicking New. For example, add a zone called inside_zone. Each interface must be assigned to a security zone and/or interface group. An interface can belong to only one security zone, but can also belong to multiple interface groups. You apply your security policy based on zones or groups. For example, you can assign the inside interface to the inside zone; and the outside interface to the outside zone. Then you can configure your access control policy to enable traffic to go from inside to outside, but not from outside to inside. Most policies only support security zones; you can use zones or interface groups in NAT policies, prefilter policies, and QoS policies. Click the IPv4 and/or IPv6 tab. IPv4—Choose Use Static IP from the drop-down list, and enter an IP address and subnet mask in slash notation. For example, enter 192.168.1.1/24 Figure 26. IPv4 Tab IPv6—Check the Autoconfiguration check box for stateless autoconfiguration. Figure 27. IPv6 Tab Click OK.
Step 4	Click Edit () for the interface that you want to use for outside. The General tab appears. Figure 28. General Tab You already pre-configured this interface for manager access, so the interface will already be named, enabled, and addressed. You should not alter any of these basic settings because doing so will disrupt the management center management connection. You must still configure the Security Zone on this screen for through traffic policies. From the Security Zone drop-down list, choose an existing outside security zone or add a new one by clicking New. For example, add a zone called outside_zone. Click OK.
Step 5	Click Save.

Configure the DHCP Server

Enable the DHCP server if you want clients to use DHCP to obtain IP addresses from the threat defense.

Procedure

Step 1	Choose Devices > Device Management, and click Edit () for the device.
Step 2	Choose DHCP > DHCP Server. Figure 29. DHCP Server
Step 3	On the Server page, click Add, and configure the following options: Figure 30. Add Server Interface—Choose the interface from the drop-down list. Address Pool—Set the range of IP addresses from lowest to highest that are used by the DHCP server. The range of IP addresses must be on the same subnet as the selected interface and cannot include the IP address of the interface itself. Enable DHCP Server—Enable the DHCP server on the selected interface.
Step 4	Click OK.
Step 5	Click Save.

Configure NAT

A typical NAT rule converts internal addresses to a port on the outside interface IP address. This type of NAT rule is called interface Port Address Translation (PAT).

Procedure

Step 1

Choose Devices > NAT, and click New Policy > Threat Defense NAT.

Step 2

Name the policy, select the device(s) that you want to use the policy, and click Save.

The policy is added the management center. You still have to add rules to the policy.

Step 3

Click Add Rule.

The Add NAT Rule dialog box appears.

Step 4

Configure the basic rule options:

NAT Rule—Choose Auto NAT Rule.
Type—Choose Dynamic.

Step 5

On the Interface Objects page, add the outside zone from the Available Interface Objects area to the Destination Interface Objects area.

Step 6

On the Translation page, configure the following options:

Original Source—Click Add ( add icon ) to add a network object for all IPv4 traffic (0.0.0.0/0).

Note

You cannot use the system-defined any-ipv4 object, because Auto NAT rules add NAT as part of the object definition, and you cannot edit system-defined objects.

Translated Source—Choose Destination Interface IP.

Step 7

Click Save to add the rule.

The rule is saved to the Rules table.

Step 8

Click Save on the NAT page to save your changes.

Allow Traffic from Inside to Outside

If you created a basic Block all traffic access control policy when you registered the threat defense, then you need to add rules to the policy to allow traffic through the device. The following procedure adds a rule to allow traffic from the inside zone to the outside zone. If you have other zones, be sure to add rules allowing traffic to the appropriate networks.

Procedure

Step 1	Choose Policy > Access Policy > Access Policy, and click Edit () for the access control policy assigned to the threat defense.
Step 2	Click Add Rule, and set the following parameters: Figure 37. Source Zone Figure 38. Destination Zone Figure 39. Apply Name—Name this rule, for example, inside-to-outside. Selected Sources—Select the inside zone from Zones, and click Add Source Zone. Selected Destinations and Applications—Select the outside zone from Zones, and click Add Destination Zone. Leave the other settings as is.
Step 3	Click Apply. The rule is added to the Rules table.
Step 4	Click Save.

Configure SSH on the Manager Access Data Interface

If you enabled management center access on a data interface, such as outside, you should enable SSH on that interface using this procedure. This section describes how to enable SSH connections to one or more data interfaces on the threat defense.

The threat defense uses the CiscoSSH stack, which is based on OpenSSH. CiscoSSH supports FIPS compliance and regular updates, including updates from Cisco and the open source community.

Note

SSH is enabled by default on the Management interface; however, this screen does not affect Management SSH access.

The Management interface is separate from the other interfaces on the device. It is used to set up and register the device to the management center. SSH for data interfaces shares the internal and external user list with SSH for the Management interface. Other settings are configured separately: for data interfaces, enable SSH and access lists using this screen; SSH traffic for data interfaces uses the regular routing configuration, and not any static routes configured at setup or at the CLI.

For the Management interface, to configure an SSH access list, see the configure ssh-access-list command in the Cisco Secure Firewall Threat Defense Command Reference. To configure a static route, see the configure network static-routes command. By default, you configure the default route through the Management interface at initial setup.

To use SSH, you do not also need an access rule allowing the host IP address. You only need to configure SSH access according to this section.

You can SSH only to a reachable interface (including an interface in a user-defined virtual router); if your SSH host is located on the outside interface, you can only initiate a management connection directly to the outside interface. When you enable SSH in a user-defined virtual router, and you want VPN users to access SSH, be sure to terminate the VPN on the same virtual router. If the VPN is terminated on another virtual router, then you must configure route leaks between the virtual routers.

SSH supports the following ciphers and key exchange:

Encryption—aes128-cbc, aes192-cbc, aes256-cbc, aes128-ctr, aes192-ctr, aes256-ctr
Integrity—hmac-sha2-256
Key exchange—dh-group14-sha256

Note

After you make three consecutive failed attempts to log into the CLI using SSH, the device terminates the SSH connection.

Before you begin

You can configure SSH internal users at the CLI using the configure user add command. By default, there is an admin user for which you configured the password during initial setup. You can also configure external users on LDAP or RADIUS by configuring External Authentication in platform settings.

You need network objects that define the hosts or networks you will allow to make SSH connections to the device. You can add objects as part of the procedure, but if you want to use object groups to identify a group of IP addresses, ensure that the groups needed in the rules already exist. Select Objects > Object Management to configure objects.

Note

You cannot use the system-provided any network object. Instead, use any-ipv4 or any-ipv6.

Procedure

Step 1	Choose Devices > Platform Settings and create or edit the threat defense policy.
Step 2	Select SSH Access.
Step 3	Identify the interfaces and IP addresses that allow SSH connections. Use this table to limit which interfaces will accept SSH connections, and the IP addresses of the clients who are allowed to make those connections. You can use network addresses rather than individual IP addresses. Click Add to add a new rule, or click Edit to edit an existing rule. Configure the rule properties: IP Address—The network object or group that identifies the hosts or networks you are allowing to make SSH connections. Choose an object from the drop-down menu, or click + to add a new network object. Available Zones/Interfaces—Add the zones that contain the interfaces to which you will allow SSH connections. For interfaces not in a zone, you can type the interface name into the field below the Selected Zones/Interfaces list and click Add. You can also add loopback interfaces and virtual-router-aware interfaces. These rules will be applied to a device only if the device includes the selected interfaces or zones. Click OK.
Step 4	Click Save. You can now go to Deploy > Deployment and deploy the policy to assigned devices. The changes are not active until you deploy them.

Deploy the Configuration

Deploy the configuration changes to the threat defense; none of your changes are active on the device until you deploy them.

Procedure

Step 1

Click Deploy in the upper right.

Step 2

For a quick deployment, check specific devices and then click Deploy, or click Deploy All to deploy to all devices. Otherwise, for additional deployment options, click Advanced Deploy.

Step 3

Ensure that the deployment succeeds. Click the icon to the right of the Deploy button in the menu bar to see status for deployments.

Troubleshooting and Maintenance

Access the Threat Defense and FXOS CLI

Use the command-line interface (CLI) to set up the system and do basic system troubleshooting. You cannot configure policies through a CLI session. You can access the CLI by connecting to the console port.

You can also access the FXOS CLI for troubleshooting purposes.

Note

You can alternatively SSH to the Management interface of the threat defense device. Unlike a console session, the SSH session defaults to the threat defense CLI, from which you can connect to the FXOS CLI using the connect fxos command. You can later connect to the address on a data interface if you open the interface for SSH connections. SSH access to data interfaces is disabled by default. This procedure describes console port access, which defaults to the FXOS CLI.

Procedure

Step 1

To log into the CLI, connect your management computer to the console port. The Firepower 2100 ships with a DB-9 to RJ-45 serial cable, so you may need a third party DB-9-to-USB serial cable to make the connection. Be sure to install any necessary USB serial drivers for your operating system. The console port defaults to the FXOS CLI. Use the following serial settings:

9600 baud
8 data bits
No parity
1 stop bit

You connect to the FXOS CLI. Log in to the CLI using the admin username and the password you set at initial setup (the default is Admin123).

Example:


firepower login: admin
Password:
Last login: Thu May 16 14:01:03 UTC 2019 on ttyS0
Successful login attempts for user 'admin' : 1

firepower#

Step 2

Access the threat defense CLI.

connect ftd

Example:


firepower# connect ftd
>

After logging in, for information on the commands available in the CLI, enter help or ? . For usage information, see Cisco Secure Firewall Threat Defense Command Reference.

Step 3

To exit the threat defense CLI, enter the exit or logout command.

This command returns you to the FXOS CLI prompt. For information on the commands available in the FXOS CLI, enter ? .

Example:


> exit
firepower#

Troubleshoot Management Connectivity on a Data Interface

When you use a data interface for manager access instead of using the dedicated Management interface, you must be careful about changing the interface and network settings for the threat defense in CDO so you do not disrupt the connection. If you change the management interface type after you add the threat defense to CDO (from data to Management, or from Management to data), if the interfaces and network settings are not configured correctly, you can lose management connectivity.

This topic helps you troubleshoot the loss of management connectivity.

View management connection status

In CDO, check the management connection status on the Devices > Device Management > Device > Management > Manager Access - Configuration Details > Connection Status page.

At the threat defense CLI, enter the sftunnel-status-brief command to view the management connection status. You can also use sftunnel-status to view more complete information.

See the following sample output for a connection that is down; there is no peer channel "connected to" information, nor heartbeat information shown:

Ping CDO

At the threat defense CLI, use the following command to ping CDO from the data interfaces:

ping cdo_hostname

At the threat defense CLI, use the following command to ping CDO from the Management interface, which should route over the backplane to the data interfaces:

ping system cdo_hostname

Capture packets on the threat defense internal interface

At the threat defense CLI, capture packets on the internal backplane interface (nlp_int_tap) to see if management packets are being sent:

capture name interface nlp_int_tap trace detail match ip any any

show capturename trace detail

Check the internal interface status, statistics, and packet count

Check for a successful DDNS update

At the threat defense CLI, check for a successful DDNS update:

debug ddns


> debug ddns
DDNS update request = /v3/update?hostname=domain.example.org&myip=209.165.200.225
Successfuly updated the DDNS sever with current IP addresses
DDNS: Another update completed, outstanding = 0
DDNS: IDB SB total = 0

If the update failed, use the debug http and debug ssl commands. For certificate validation failures, check that the root certificates are installed on the device:

show crypto ca certificates trustpoint_name

To check the DDNS operation:

show ddns update interface fmc_access_ifc_name


> show ddns update interface outside

Dynamic DNS Update on outside:
    Update Method Name Update Destination
    RBD_DDNS not available

Last Update attempted on 04:11:58.083 UTC Thu Jun 11 2020
Status : Success
FQDN : domain.example.org
IP addresses : 209.165.200.225

Power Off the Firewall

It's important that you shut down your system properly. Simply unplugging the power or pressing the power switch can cause serious file system damage. Remember that there are many processes running in the background all the time, and unplugging or shutting off the power does not allow the graceful shutdown of your firewall system.

You can power off the device using the management center device management page, or you can use the FXOS CLI.

Power Off the Firewall Using CDO

You can shut down your system properly using the management center.

Procedure

Step 1	Choose Devices > Device Management.
Step 2	Next to the device that you want to restart, click Edit ().
Step 3	Click the Device tab.
Step 4	Click Shut Down Device () in the System section.
Step 5	When prompted, confirm that you want to shut down the device.
Step 6	If you have a console connection to the firewall, monitor the system prompts as the firewall shuts down. You will see the following prompt: `System is stopped. It is safe to power off now. Do you want to reboot instead? [y/N]` If you do not have a console connection, wait approximately 3 minutes to ensure the system has shut down.
Step 7	You can now turn off the power switch and unplug the power to physically remove power from the chassis if necessary.

Power Off the Device at the CLI

You can use the FXOS CLI to safely shut down the system and power off the device. You access the CLI by connecting to the console port; see Access the Threat Defense and FXOS CLI.

Procedure

Step 1	In the FXOS CLI, connect to local-mgmt: firepower # connect local-mgmt
Step 2	Issue the shutdown command: firepower(local-mgmt) # shutdown Example: `firepower(local-mgmt)# shutdown This command will shutdown the system. Continue? Please enter 'YES' or 'NO': yes INIT: Stopping Cisco Threat Defense......ok`
Step 3	Monitor the system prompts as the firewall shuts down. You will see the following prompt: `System is stopped. It is safe to power off now. Do you want to reboot instead? [y/N]`
Step 4	You can now turn off the power switch and unplug the power to physically remove power from the chassis if necessary.
