Both the 5506-X (rugged version and wireless), and 5508-X now come with a FirePOWER services module inside them. This can be managed from either ASDM* (with OS and ASDM upgraded to the latest version), and via the FireSIGHT management software/appliance.

*UPDATE: All ASA ‘Next-Gen’ firewalls can now have their Firepower Service Module managed from the ASDM.
2. The next step might seem strange if you are used to working with Cisco firewalls, but you need to make sure there is no IP address configured on the management interface. Try to think of it as just the hole that the FirePOWER services module (which will get its own IP) speaks out though.
Petes-ASA# configure terminal Petes-ASA(config)# interface Management1/1 Petes-ASA(config-if)# no nameif WARNING: DHCPD bindings cleared on interface 'management', address pool removed Petes-ASA(config-if)# no security-level Petes-ASA(config-if)# no ip address
3. So it should look like this;
Petes-ASA(config-if)# show run : Saved ASA Version 9.3(2)2 ! ----Output removed for the sake of brevity---- ! interface Management1/1 management-only no nameif no security-level ! ----Output removed for the sake of brevity----
4. Lets make sure the FirePOWER service module is ‘up’ and healthy.

5. The SFR module is actually a Linux box that’s running within the firewall, to connect to it you issue a ‘session sfr’ command.
- Default Username: admin
- Default Password: Sourcefire (capital S)
- Default Password (after version 6.0.0): Admin123 (capital A)

6. Set a new password.

Press any key to continue.
8. Now you need to ‘send’ traffic though the module, in this case I’m going to send all IP traffic though, I’m also going to set it to ‘fail open’, If you set it to fail closed then traffic will cease to flow though the firewall if the FirePOWER services module goes off-line. I’m making the assumption you have a default policy-map applied.
Petes-ASA(config)# access-list SFR extended permit ip any any Petes-ASA(config)# class-map SFR Petes-ASA(config-cmap)# match access-list SFR Petes-ASA(config-cmap)# exit
9. Add that new class-map to the default policy-map.
WARNING: If you are going to set ‘fail-close‘ then make sure your SFR module is operating normally, or you will cause downtime, best to do this in a maintenance window!)
Petes-ASA(config)# policy-map global_policy Petes-ASA(config-pmap)# class SFR Petes-ASA(config-pmap-c)# sfr fail-open Petes-ASA(config-pmap-c)# exit Petes-ASA(config-pmap)# exit
10. Save the changes.
Petes-ASA(config)# write mem Building configuration... Cryptochecksum: 72c138e3 1fa6ec32 31c35497 621cff02 35819 bytes copied in 0.210 secs [OK]

12. Now when you connect to the ASDM you can manage the FirePOWER services module.Note: I have seen some firewalls that flatly refuse to connect to the Firepower Services Module, and give an error ‘unable to connect on port 443’ every time you launch ASDM. I just re-image the module and load in a fresh install (40 mins to an hour), and start again.
Code to Copy & Paste
If you are lazy like me!
access-list ACL-FirePOWER extended permit ip any any class-map CM-SFR match access-list ACL-FirePOWER exit policy-map global_policy class CM-SFR sfr fail-open exit exit write mem
Note If you get an unable to connect error see the following article;
13. I suggest you update everything first, the ASA will configure an access control policy set to allow and inspect all traffic by default, which we will edit, set everything to update on a schedule, (rule updates and geolocation info).
Cisco FirePOWER Services Adding Licences (ASDM)
In the box with the firewall, you will have an envelope, you don’t need to open it (as below) because the PAK number you need is printed on the outside anyway. This is the firewalls CONTROL LICENCE, it allows it to be managed, we will install it into the ASDM, if you have a SourceFIRE appliance to manage the firewall you would install it there. You need two bits of information the PAK and the LICENCE KEY of the FirePOWER module, (See Below).
The Licence Key is the MAC address of the Module, (Not the ASA). You can find it at Configuration > ASA FirePOWER Configuration > Licence. This is also where you will add all the licences. Go to www.cisco.com/go/licence and register the licence (and any additional licences i.e. AMP, Web filtering, etc.)
The Licence(s) will be emailed to you open them in a text editor and copy the text of each licence. You can see I’ve indicated below what you should be copying.
Paste that into the ASDM > Submit Licence.
It should say success, if it fails you’ve pasted to much text, or there’s a problem with the licence.
Review you licences, here Ive added AMP and web filtering but Ive yet to add the control licence. If you don’t add the control licence then when you try and edit the access control policy it will say you need a PROTECTION LICENCE (confusingly!)
FirePOWER Services Setup IPS
Disclaimer: These settings, (and allotters below,) are to get you up and running, As with any security device, you need to tune settings accordingly. Please don’t follow these instructions, then email me with complaints that you been attacked by ISIS/Scammers/Bots etc.
You get an IPS/IDS Licence with any of the subscription based licences, its less hassle to set this up before the the access control policy. Configuration > ASA FirePOWER Configuration > Policies > Intrusion Policy > Create Policy > Give it a name > I tend to use ‘Balanced Security and connectivity’ look at the other options and choose whichever you prefer > Create and Edit Policy.
Give the policy a name > Commit changes (I accept all the defaults).
FirePOWER Services Enable Malware Inspection and Protection
Note: Obviously this needs you to have added an AMP Licence!
Configuration > ASA FirePOWER Configuration > Policies > Intrusion Policy > Files > New File Policy > Give it a name > Store FirePOWER Changes.
Add new file rule > I add everything > and Set it to ‘Block Malware’ > Store FirePOWER Changes.
“Store ASA FirePOWER Changes”.
Warning: Nothing will be inspected, until you add this file policy to an access control policy.
ASA FirePOWER Services Edit / Create Access Control Policy
I renamed the default policy, Note: Even though I’ve called it ‘Base-Access-Control-Policy’ you can only apply one policy, you just add different rules to the policy as required. Add Rule.
In Source Networks > Add in ‘Private Networks’ (See Warning Below).
Inspection Tab > Add in the IPS and file policy you created above (That’s why I’ve done it in this order).
I set it to log at the end of the connection > Add.
“Store ASA FirePOWER Changes”.
FirePOWER Private Networks Warning
Private networks only cover RFC1918 addresses, if you LAN/DMZ etc subnets are different you should create a new Network object, then add the subnets for your network. If you do this, then substitute your network object every time I mention the Private Networks object.
Blocking a Particular URL with FirePOWER Services
Even if you don’t have a Web Filtering licence you can block particular URL’s here Im going to block access to Facebook. Configuration > ASA FirePOWER Configuration > Object Management > URL > Individual Objects > Add URL > Note Im adding http and https.
Then add a rule to your existing access control policy ABOVE the permit all rule, (they are processed like ACLS from the top down). Set the source network to your private subnets.
On the URLs tab add in your URL objects and set the action to block with reset, or Interactive block with reset if you want to let the users proceed to Facebook after a warning.
Note: If you have a Web filtering Licence you can select ‘Social Networking’ from the Categories tab, and that would also block Facebook, and Twitter etc.
ASA FirePOWER Services Commit and Deploy The Changes
FirePOWER services behaves the same on-box as it does when you use the SourceFIRE Appliance, you can make changes but nothing gets deployed until you commit the changes. If you have made a change then there will be a ‘Store ASA FirePOWER services button active. Then you need to select File > Deploy FirePOWER Changes.
Note: You will only see the Deploy option on SFR modules running 6.0.0 or newer.
Even now its not deployed, it takes a while, to see progress navigate to Monitoring > ASA FirePOWER Monitoring > Task Status > It will probably have a ‘running’ task.
Wait until the policy deployment says completed before testing.
