Snort 2.9.7.0 – Preview of new OpenAppID feature
-
Words cant describe how I feel about this….. LOVE
-
This is awesome! Thank you for all your work!
So does that mean that this feature can be used instead of setting up a proxy and block lists to block certain websites/applications? Also, this works through SSL without the need of any additional software to MITM the connection?

I'm not sure exactly how the SSL part works.I know it is not actually decoding the entire SSL session, and it does not need any kind of MITM infrastructure. I did attempt to browse directly to https://www.facebook.com and got blocked. Also got all the alerts you see in my screen capture. Also, you can see the destination port was 443, so that's further evidence SSL was in play. I was using two VMware VMs. One was a pfSense box and the other was a WinXP box configured so it was using the pfSense box as the gateway.The detectors are open source and written as Lua scripts, so you can download the package and examine the internals to see how it works.
EDIT: I took a look at some of the Lua scripts, and for SSL sites they basically look at the SSL Cert exchange and pick out SSL hosts from it. That's how it can identify Facebook, for example, in an HTTPS URL. It's not looking inside the encrypted SSL, instead it examines the initial SSL cert set up conversation to key off the host.

My part of the new code is complete. There are some additional options being considered by the pfSense Team to take full advantage of the new OpenAppID feature. I am waiting for them to notify me when they are ready for me to post the code for final review.

You are making difficult even for me choosing between snort and suricata :D
An excellent feature, maybe this will help all the people wishing to block specific things (facebook, youtube) without any additional package.

Sorry about that … ;D.
Will be posting a Suricata 2.0.4 preview thread shortly. I'm adding GeoIP and IP Reputation support to Suricata in the 2.0.4 update. That pull request is currently posted for review by the pfSense developers.

Just installed the package (upgraded from 2.9.6.2), and Snort disappeared from the Services.
System:Package Manager still lists the snort package as installed.
Rebooting pfSense does not help. Any ideas?
Thank you

Same here… lost Snort selection under Services.
Can access it with this link ... http://x.x.x.x/snort/snort_interfaces.php

OpenID detection package link comes up blank when the the option is checked.
-
Ya, when enabling, it gives the error "You must supply a download URL in the box provided in order to enable OpenAppID detectors!"
But, there is no box. :(

Did you stuck on the Install screen that says "Waiting for Snort to start…."? and you clicked on something else?
I found if you didn't let the install finishes Snort will disappear from the Service list.
Because there is a bit more installs process after the "Waiting for Snort to start..." message.
I had my search method set on AC for both WAN and LAN and it takes AGES and I mean AGES for Snort to start.Hope this helps.

Thanks to Renato for helping me out. A fix was posted this morning that should correct the bogus validation error when enabling the new OpenAppID download under GLOBAL SETTINGS.
I will post a separate release notes thread.
For those of you having the service disappear from the menu, make sure you have space available on /tmp and /var. Also give Snort plenty of time to restart. Depending on your setup, this can take a while. You will get a confirmation message on the screen.

Wow, this is great, thank you!
I have run into an issue writing the example rule, and I'm wondering if it is because I'm on the 64-bit version of pfsense, or perhaps I just can't type :) Here is what I entered in the LAN custom rules:
alert tcp $HOME_NET any -> $EXTERNAL_NET any (msg:"facebook Reddit or Twitter applicaionts"; appid: facebook facebook_apps reddit twitter twitter_link; sid:1000000; classtype:misc-activity; rev:1;)When I hit save, I get this error:
https://www.dropbox.com/s/ux2b3bz6vypu2gz/Screenshot%202014-12-19%2010.17.58.png?dl=0text is Custom rules have errors: Fatal Error, Quitting…ERROR: /usr/pbi/snort-amd64/etc/snort/snort_50141_em/rules/custom.rules(1) Rule options must be enclosed in '('and')'.
I have tried modifying my input to match what it suggests, but I keep getting the same error no matter what I do. Have I missed something blindingly obvious, or is there possibly something "different" about 64-bit pfsense that might be causing this - or anything else I cna check, really. Thanks, I'm really looking forward to using this!

Try this
