The Center for Internet Security (http://cisecurity.org) needs your help with creating the first CIS PAN-OS security benchmark. We're looking for volunteers with PAN-OS experience to contribute in security discussions, recommendations, editing, figuring out CLI commands for automated auditing, and many other tasks, from expert to beginner. Spend as little or as much time contributing as you'd like. The CIS benchmark uses this document from the SANS reading room as a starting point--https://goo.gl/OHgo77 but there's plenty of work to be done before v.1 can be released. Sign up here under "CIS Palo Alto Networks Benchmarks": http://benchmarks.cisecurity.org/community/projects/

Thanks, Steven Puluka . That will be a little tough in our environment, but should give us at least some insight. I wish there were a "log, continue" option that I could just place at the top of the shared pre-rules in Pano. Once traffic hit that rule, it wouldn't permit or deny, but simply create a log entry and continue down the ruleset. jkim@copperriverit.com - Wow, I d idn't realize OpenDNS offered a threat feed compatible with Palo's DBLs. I actually sat in a presentation by the OpenDNS guys at DEFCON this year. They're doing some amazing work. Thanks!

parmas - Can you say which block lists you've used in production?

RyanF · ‎12-17-2014

Good point. We are already using pan-db. Just looking for additional ways to help keep out the bad guys.

I'd love to integrate lists of known malicious IPs like those in the links below into dynamic block lists, but I'm worried about overblocking or a bad feed hosing us. Has anyone used feeds similar to the ones below, either free or paid? What was your experience? http://rules.emergingthreats.net/fwrules/emerging-Block-IPs.txt http://malc0de.com/bl/IP_Blacklist.txt http://panwdbl.appspot.com/lists/openbl.txt Others: http://panwdbl.appspot.com/

In what I've seen so far, I think you are correct--only Netflow can provide what we need here. A shame that's not built-in to Panorama.

The problem is, we don't know what IPs we need to investigate. The ultimate question is, how can we accurately see bytes transferred (and source/destination IPs) in a given period of time? The data transferred with established (non-terminated) sessions don't show up in any report, which could be a huge missing piece.

RyanF · ‎12-03-2014

Here's the scenario: 1) 1 week ago, a session from 10.1.1.1 and 10.2.2.2 is established. Normally, data transfer is very low. 2) Within that session, 100GB of data is suddenly transferred one day between 6pm and 7pm, pegging the site's Internet bandwidth. 3) The data transfer becomes very low again after the burst. The session doesn't terminate until 1 week later. Observations: - If we look at ACC during that 1 hour burst, the traffic doesn't show up at all. - If we look at the session browser, all we see is total transferred bytes since the session was established. Question: - When we try to figure out what's using up the bandwidth in a particular time frame, how can we see bytes transferred and source/destination IPs for established sessions that remain active? (The Network Monitor is horribly inflexible and doesn't produce enough detail to be useful in our actual scenario)

There's a ton of fantastic best practices guides on this site in addition to the admin guides. I was wondering if a best practices security configuration benchmark or checklist exists for PA firewalls. Something I can hand an IT auditor, similar to this: http://goo.gl/JgmTTc

Awesome! Thank you for the quick response! You saved me a call to support.

To protect web servers with this threat signature, do we need to have SSL inbound inspection enabled?

RyanF · ‎11-11-2014

Thanks, Dorsey. Are there any others you've gotten feedback on? Any vendors we should probably...ummm...put lower on our list?

RyanF · ‎11-10-2014

We have a need for 24x7 monitoring, so I wanted to explore partnering with an MSSP vs. setting up our own SOC. Anyone have experiences to share? We'll probably start discussion with one of these partners, but wanted to get feedback first: https://www.paloaltonetworks.com/partners/managed-security-services-provider.html

For those of you with global Palo deployments, here's a paper to get you started on what you should know about employee privacy issues. This issue can be complex in countries outside of the U.S. "Next Generation Firewalls and Employee Privacy in the Global Enterprise” http://www.sans.org/reading-room/whitepapers/legal/generation-firewalls-employee-privacy-global-enterprise-35467

Thank you, essnet! Nothing else worked for me, but manually appending the intermediate cert to the primary in XML did the trick! I also had to reboot the devices for the change to take effect. I would've thought after 1.5 years that would be fixed. Thanks again!
