Cisco ASA Firepower Threat Defense (FTD): Download and Installation/Setup ASA 5500-X. FTD Management Options - 5.0 out of 5 based on 6 votes

One Appliance – One Image is what Cisco is targeting for its Next Generation Firewalls. With this vision, Cisco has created a unified software image named “Cisco Firepower Threat Defense”.  In this FirePOWER series article we’ll cover the installation of Firepower Threat Defense (FTD) on a Cisco ASA 5500-X series security appliance. We’ll also explain the management options available: Firepower Management Center (FMC) which is the old FireSIGHT and Firepower Device Manager (FDM).

Cisco Firepower Threat Defense (FTD) is a unified software image, which is a combination of Cisco ASA and Cisco FirePOWER services features that can be deployed on Cisco Firepower 4100 and the Firepower 9300 Series appliances as well as on the ASA 5506-X,ASA 5506H-X, ASA 5506W-X, ASA 5508-XASA 5512-X, ASA 5515-X, ASA 5516-X, ASA 5525-X, ASA 5545-X, and ASA 5555-X. However, at the time of writing, the Cisco Firepower Threat Defense (FTD) unified software cannot be deployed on Cisco ASA 5505 and 5585-X Series appliances. 

Understanding Cisco Firepower Threat Defense Management & Capabilities

Simplifying management and operation of Cisco’s Next Generation Firewalls is one of the primary reasons Cisco is moving to a unified image across its firewall appliances.

Currently the Firepower Threat Defense can be managed through the Firepower Device Management (similar to Cisco’s ASDM) and Firepower Management Center (analyzed below).

Managing Options for FirePOWER Services and Firepower Threat Defense (FTD)

Managing Options for FirePOWER Services and Firepower Threat Defense (FTD)

It should be noted that the Firepower Device Management software is under extensive development and is not currently capable of supporting all configuration options. For this reason it’s best to rely on the Firepower Management Center to manage the Cisco Firepower Threat Defense system.

The Firepower Management Center, also known as FMC or FireSIGHT, is available as a dedicated server or virtual image appliance (Linux based VM server) that connects to the FirePOWER or Firepower Threat Defense and allows you to fully manage either system. Organizations with multiple Firepower Threat Defense systems or FirePOWER Services would register and manage them from the FMC.

Alternatively, users can manage the Firepower Threat Defense (FTD) device using the Firepower Device Manager (FDM) – the concept is similar to ASDM.

Currently the latestCisco Firepower Threat Defense (FTD) unified software image available is version 6.2.x .

The Cisco Firepower Threat Defense is continually expanding the Next-Generation Firewall Servicesit supports which currently includes:

  • Stateful Firewall Capabilities
  • Static and Dynamic Routing. Supports RIP, OSPF, BGP, Static Routing
  • Next-Generation Intrusion Prevention Systems (NGIPS)
  • URL Filtering
  • Application Visibility and Control (AVC)
  • Advance Malware Protection (AMP)
  • Cisco Identity Service Engine (Cisco ISE) Integration
  • SSL Decryption
  • Captive Portal (Guest Web Portal)
  • Multi-Domain Management
  • Rate Limiting
  • Tunnelled Traffic Policies
  • Site-to-Site VPN. Only supports Site-to-Site VPN between FTD appliances and FTD to ASA
  • Multicast Routing Shared NAT
  • Limited Configuration Migration (ASA to Firepower TD)

While the Cisco Firepower Threat Defense is being actively developed and populated with some great features, we feel that it’s too early to place it in a production environment. There are some stability issues, at least with the FTD image on the ASA platform, which should be ironed out with the newer software releases.

If you are already in the process of installing FTD on your ASA then you should heavily test it before rolling it out to production.

Due to the issues encountered, we were forced to remove the FTD installation by reimaging our ASA 5555-X Appliance with Cisco ASA and FirePOWER Services images. We believe the “Cisco Firepower Threat Defense” unified software image is very promising but requires some more time to reach a more mature and stable version.

Problems/Limitations Encountered with Cisco Firepower Threat Defense

While small deployments might be able to overcome the absence of many desired features (e.g IPSec VPN support), enterprise environments will certainly find it more challenging.

Depending on the environment and installation requirements customers will stumble into different limitations or issues. For example, on our ASA 5555-X we had major delays trying to push new policies from the Firepower Management Centre (FMC) to the newly imaged FTD ASA. With a total of just 5 policies implemented it took over 2 minutes to deploy them from the FMC to the FTD.

We also found that we were unable to configure any EtherChannel interfaces. This is considered a major drawback especially for organizations with multiple DMZ zones and high-bandwidth traffic requirements. Cisco has an official announcement for this right here.

In addition to the above, when we completed the conversion of our ASA to the FTD software we needed to open a TAC Service Request in order to get transfer our ASA License to the FTD image, adding additional unnecessary overhead and confusion. We believe this should have been automatically done during the installation process.

Cisco ASA Firepower Threat Defense (FTD) Installation – Quick Overview

Reimaging the Cisco ASA 5555-X Appliance to install the Cisco Firepower Threat Defense image is fairly simple once you understand what needs to be done. Here are the steps in the order they must be executed:

Download the Cisco Firepower Threat Defense Boot & System Image

Using a valid CCO account that has the necessary software download privileges visit: Downloads Home>Products Security>Firewalls>Next-Generation Firewalls (NGFW)>ASA 5500-X with FirePOWER Services and select Firepower Threat Defense Software:

Downloading Cisco ASA 55xx Firepower Threat Defense software

Alternatively click on the following URL: Firepower Threat Defense Software Download

Next, select and download the latest boot image and system version. In our example this isversion 6.2.0:

Reboot ASA, break the startup/boot sequence

When ready reboot the ASA appliance. During the boot process hit Break or Esc to interrupt boot:

It is strongly recommended you have a complete backup of your ASA Configuration and software before proceeding with the next steps which will erase the configuration and all files

At this point we have successfully interrupted the boot process and can proceed to the next step. 

Upload the Boot Image and Boot the ASA Firewall

We now need to configure the necessary parameters on the ASA Firewall to download the Cisco Firepower Threat Defence Boot Image. Ensure you have an FTP/TFTP server installed and configured to allow the Firewall to download the image/system files.

Now connect to the ASA console port using a terminal access application, e.g. Putty, configured with the following serial port settings:

  • 9600 baud
  • 8 data bits
  • No parity
  • 1 stop bit
  • No flow control

Ensure the Cisco ASA 5500-X appliance is running rommon version v1.1.8 or greater by using an IOS command show module to ensure re-immaging will be successful. If the rommon version is earlier than v1.1.8 then the ASA Appliance needs a rommon upgrade

Next, configure the ASA Firewall with the necessary network settings/variables so it can access the image and system files previously downloaded. ASA 5555-X firewall uses a built-in management interface, hence no need to specify the management interface.

rommon #1> address 10.32.4.129
rommon #2> server 10.32.4.150
rommon #3> gateway 10.32.4.150
rommon #4> file ftd-boot-9.7.1.0.cdisk
rommon #5> set
ROMMON Variable Settings:
 ADDRESS=10.32.4.129
 SERVER=10.32.4.150
 GATEWAY=10.32.4.150
 PORT=Management0/0
 VLAN=untagged
 IMAGE=ftd-boot-9.7.1.0.cdisk
 CONFIG=
 LINKTIMEOUT=20
 PKTTIMEOUT=4
 RETRY=20

Explanation of commands:

- Address: IP address of ASA Firewall
- Server: The TFTP server from where the ASA will download the image
- Gateway: The IP address of the network gateway. Mandatory even if the TFTP server is within the same logical network
- File : The name of the file
- Set: Shows the rommon settings

The Sync command will save the NVRAM parameters, effectively “enabling” the configuration changes. It’s advisable to try and ping the TFTP server. This will not only confirm the TFTP server is reachable but also populate the ARP table of the ASA Firewall:

rommon #6> sync

Success rate is 95 percent (19/20)

When ready, issue the tftpdnld command to initiate the download of the boot image to the ASA Firewall. Once downloaded the system will automatically boot the image file:

rommon #7> tftpdnld

Install Firepower Threat Defense System Software 

At this point our Firewall has successfully downloaded and booted the Boot image and is ready to accept the System image. At the prompt type setup and simply follow the bouncing ball. The setup process will gather important configuration parameters for the FTD device such as Hostname, IP address, Subnet mask, Gateway, DNS servers and more

Many of the configuration questions involve a yes/no answer. The default value that will be selected when leaving the parameter blank and hitting enter is marked in square brackets [ ]:

Press ENTER to continue...

At this point the appliance’s initial configuration phase is complete and ready to begin downloading the FTD system image

To initiate the image download use the system install ftp://10.32.4.150/ftd-6.2.0-362.pkg and replace the IP address portion with your FTP server’s IP address.

During the installation, the process will ask for the necessary credentials to authenticate to the FTP server. Right before the point of no return the system will ask for a final confirmation before erasing the appliance’s disk and initiating the upgrade. When the system image installation is complete, the system will require the user to hit enter to reboot.

Unnecessary output e.g. dots (….) have been removed from the log to make it easier to read and understand.

Broadcast message from root@FIREWALLCXFTD (ttyS0) (Thu Mar 16 05:46:03 2017):
The system is going down for reboot NOW!

The ASA FTD Appliance will now reboot. While this process is underway you will see a lot of information during shutdown and startup. When booting into the FTD system image for the first time it is normal to see a number of error/warning messages – do not be alarmed.

When the system has successfully booted it will require you to login using the default username (admin) & password (cisco123) then require you to press Enter to present Cisco’s EULA which must be accepted at the end by pressing again the enter key or typing YES:

Cisco ASA5555-X Threat Defense v6.2.0 (build 362)

Finally the last step involves changing the default admin password and configuring again the system’s network settings.

While it might seem repetitive and pointless to configure the network settings three times during the FTD boot image and system image installation, this allows companies to perform these necessary preparation tasks in an isolated environment, e.g. lab room, to get the device ready for the final deployment that will be in the production environment.

Similar to the previous steps, pressing enter will accept the default value shown between the brackets [ ]:

Summary

Cisco’s Firepower ThreatDefense(FTD) istheNext-Generation Firewall solution that will eventually replace the well-known ASA software. While FTD is still in its early years it is rapidly being adopted by organizations across the globe. It is important to understand the current limitations of FTD before moving it into a production environment. For example, important features such as site-to-site VPN are not currently supported, however, it does have a great clean and intuitive GUI interface!

For many, installing Cisco’s Firepower Threat Defense on an ASA Firewall appliance can be a confusing task. Our Cisco Firepower Threat Defense (FTD) installation guide has been designed to simplify the process by providing step-by-step instructions presented in an easy-to-understand format while also covering Cisco Firepower Threat Defense management options.
