Problem

You have been able to manage your firewalls Internal SFR module for  while using the ASDM

Setup FirePOWER Services (for ASDM)

For most people that’s fine, but if you have a lot of FirePOWER devices to manage that does not scale well. In those cases you should use theFMC  (FirePOWER Management Center). Here ‘Im going to use the Vmware virtual appliance, (at time of writing there is no Hyper-V version).

FirePOWER Management Center

This lets you create policies centrally and then deploy them to your devices in bulk.

Solution

Deploy the FirePOWER Management Center Appliance

Obviously before you start you need to have VMware (ESX or vCenter). With 250GB of storage free, (you can deploy it thin provisioned). You will also need to allocate 8GB of RAM and 4 virtual CPUs. Whichever network (or VMware port Group) you connect the appliance to it needs to have IP connectivity to the devices you intend to manage.

Download the FMC Appliance: Be aware it downloads in tar.gz format so on a Windows machine you will need something like 7Zip to uncompress the files. You WONT find the file under the firewalls, they are listed under;

Downloads > Produces > Security > Firewalls > Firewall Management > Firepower Management Center Virtual Appliance

Make Sure: You download the same version that is installed on the modules you want to manage! (‘show module’ on the ASA will yell you).

Get the files extracted and on a machine that you can access your VMware infrastructure from;

Download Cisco FirePOWER

The appliance comes in OVF format if you are unsure how to import an OVF file see the following article;

VMware vSphere – How to Import and Export OVF and OVA Files

You will need to accept the EULA, then set the admin password, and some basic IP settings.

Import FMC Appliance

I’ve got IPv6 disabled, if you want to address the appliance with IPv6 enter the details here.

FMC IP Settings

Even after the appliance has been imported and powered on it can take 20-30 minutes before you can log on. At this point I would go and do something else. If you really must, then open a ‘console’ session and wait until the logon prompt is shown. You can then logon to the web portal.

Log into FirePOWER

Go to System > Updates > Download and install any updates > Visit both the ‘Rule Updates’ and the ‘Geolocation Updates’ tabs and set a time to download them.

Don’t Install the licences Just Yet! Add your devices to the FMC first, then if there’s a problem and you need to rebuild/redeploy, you don’t have to go cap in hand to Cisco licensing to get the licences re-armed. To add the SFR devices see the following article;

Cisco Add FirePOWER Module to FirePOWER Management Center

Network Discovery: Older version of the FMC used to only look for RFC 1918  IP ranges, This was changed at some point to 0.0.0.0/0 so you couldn’t misconfigure the system by having a private address space internally for example. This was a good idea but Ive seen some firewalls fall over trying to run discovery on every IP address they see!  So lets manually add in our subnets. Objects > Object Management > Add Network > Add Object > Add one for you internal network(s).

FirePOWER Create Object

Policies > Network Discovery > Remove the 0.0.0.0 Rule.

FMC Default Discovery

Create a new discovery rule using just your subnet(s).

Default Discovery Rule FMC

 

Adding Licences To FirePOWER Management Center

You used to have to licence the appliance itself, after version 6 you don’t need to do that, if you have a licence and you try and apply it nothing happens and you just see this message;

FireSIGHT Licence

Note: FireSIGHT is the old name for FirePOWER Management Center.

What Licences do I need to Add? Your Next Generation Firewalls now come with a ‘CONTROL LICENSE‘ in the box, it is in a large white card envelope, you don’t need to open it the number you need is on the front of the envelope. You add a control licence for every device you want to manage (they do not expire).

ASA Control License

System > Licences > Classic Licenses > You need to take a note of the ‘Licence Key’, (which is the MAC address of the appliance with a 66 in front of it). This is the serial number you need to enter on the Cisco licensing portal.

FirePOWER Install Licences

When you get the licence back, if you open it in a text editor, it will look like this (its essentially a digital certificate). Copy everything from ‘— BEGIN‘ to ‘License —‘ 

Protect and Control License

Paste in the text > Submit License.

Install FirePOWER Licenses

Repeat for each licence (IDS, AMP, URL Filtering ,etc)

Successfully Installed FirePOWER

You will also need to allocate the licenses to devices. Devices > Device Management Select the Device in question > Edit.

Allocate FirePOWER License

Device > License Section >Edit > Allocate accordingly.

Allocate SFR Control License

Configuring FirePOWER Intrusion Policy

To use an intrusion policy the devices each need a ‘Protection‘ licence. Note: You get a protection licence now automatically when you add a CONTROL licence, but you still need to pay a subscription to legally obtain the updates.

Policies > Intrusion > Create Policy.

IDS IPS Config

Give the policy a recognisable name > Create and Edit policy.

FirePOWER Intrusion Policy

The policy it creates is based on the ‘Balances Security and Connectivity’ Template. You might want to add a few extra rules > Rules > Blacklist > Select All.

Intrusion Blacklist FMC

Rule State > Drop and Generate Events.

IPC Configuration Cisco

Repeat for ‘Malware’. Note: This does NOT require and AMP licence@

FirePOWER Malware IDS

Repeat for  PUA (Probably Unwanted Applications).

PUA Cisco FirePOWER

Repeat for ‘Indicator Compromise‘.

IPS compromise Cisco

Repeat for ‘Exploit Kit‘.

FirePOWER Exploit Kit

Search for ‘1201’ and locate the ‘INDICATOR-COMPROMISE 403 Forbidden’ rule and DISABLE IT.

FirePOWER 304 Forbidden

Policy Information > Commit Changes > OK.

Save FirePOWER IPS Policy

Note: To be used, the Intrusion policy needs to be declared in an Access control policy (or set as a Default Action).

Apply IDS FMC

Also in the Access Policy set the logging to ‘Log at the end of connection‘.

FirePOWER Logging

As mentioned above you can also set it as the ‘Default Action‘.

Default IDS Policy

Configuring FirePOWER AMP and File Policy

You need an AMP, (subscription based licence) to enable the ‘Malware Cloud Lookup, or Block Malware‘ Actions, but you can have a file policy and block specific file types.

Polices > Access Control > Malware and File > New File Policy.

FirePOWER AMP Policy

Give the policy a name you will remember > Save.

AMP File Policy Cisco

Action = Malware Cloud lookup > Add in the files you want to scan > Below I’ve set it to store unknown files > Save.

AMP Cloud Lookup

Then create another rule below that that detects all files.

Detect AMP FirePOWER

As above the file policy wont be applied to anything unless you specify it in an access policy.

Apply AMP Policy

In the rule also set the logging to ‘log at the end of connection’.

AMP Logging FirePOWER

 

Configuring FirePOWER URL Filtering Policy

You need to have a URL filtering licence allocated to the devices you want to use this policy on.

Unlike File policies and Intrusion policies, URL filtering is configured directly on your Access Control policy > Add Rule.

FirePOWER URL Filtering Rule

Here’s an example of blocking some categories you don’t want viable in tour organisation.

URL Filtering Policy

In a rule that only has URL filtering set the login to ‘Log at the beginning of the conneciton‘.

URL Logging Cisco FMC

 

When done, don’t forget to ‘Deploy‘ the new policy to your managed devices. Deploy > Select Devices > Deploy.
