Monitoring with FTD firepower 2100

marcio.tormente — Fri, 21 Feb 2020 16:33:40 GMT

Hello guys!

I have no experience with FTD firepower and I'm lost with the monitoring.

In the ASA using ASDM I can make monitoring in real time to se where the traffic is blocking or not, but I have no idea how can I do it using Firepower.

Anyone can help me with this case?

Thanks

Marcio

Hi Marcio

With in the FMC (Firepower Management Center), you can use Analysis > Connection events to filter and drill down on standard connection events that pass through the managed devices.

You can use Analysis > Intrusion Events to assess what is being blocked/monitored by the Snort engine.

Also, if you have the network discovery policy configured to build up host intelligence of your internal protected nodes (Desktops, laptops, servers etc), Analysis > Context Explorer will give you accurate IOCs (Indications of Compromise) and what devices/alerts should be triaged first.

As a general rule of thumb, the Intrusion alerts are rated 1-4 then 0 (1 being critical, 0 being informational). Look at the critical ones first.

The Access Control Policy ties in all the 'sub policies' together (File/Malware, Prefilter (Layer 1-4), Intrusion (> Layer 7), SSL, DNS etc.)

Hope this helps.

Phil

Hello Phil!

thanks for your support.

I tried as you said, but after go to "Analysis > Connection events", I have many option in the "jump to" as I can show in the attached, if I change to "host" for example, I have no result.

Or If I make a filter by network and put the IP of the host, again I have no result. Do you know why?

thanks

Hi,

Do you have an ACP configured with logging enabled?

Cheers

Also, as well as ACP configured with logging, have you tried increasing the time window (top right of the table)?

sorry, but what is ACP?

Re: Monitoring with FTD firepower 2100

ACP is access control policy. It's where all the ACL (Access control list) style rules and additional upto Layer 7 inspection is configured.

Check this out:

Have you added your FTD devices to the FMC already? do you have licensing sorted? (if not, no problem, use evaluation mode for a 90 day window)

Yes I have the ACP configured and the device is on the FMC phisical appliance with the the normal license (not evaluation).

So do have you ACP rules configured with logging:

Edit the rule, click Logging tab, either Log at Beginning and/or End of
Connection
