Update to Bro 2.5.2 and raspbian 201711-29 #3

ramirezversion · 2017-12-28T12:03:47Z

I am having some errors installing Bro 2.5.2. I am working to try to update to the latest version of tools. Could you help me?

gebhard73 · 2017-12-28T15:20:11Z

you may try my pull request (which hasn't been accepted yet):
#2
and make sure to use my repo for download of the code:
https://github.com/gebhard73/foxhound-nsm
git clone https://github.com/gebhard73/foxhound-nsm.git
pls also note that an update will have side effects (because the installation file isn't yet suitable for updates but only for clean installs); I'd suggest investing in a new SD card...
Any feedback is appreciated.

ramirezversion · 2017-12-29T06:37:37Z

Thank you gebhard73. I found your pull yesterday and I am trying to install following it better than original. If I found some error or mistake I will feedback you. I have started again from an empty SD card. Thanks for your kindly help. Regards, 2017-12-28 16:20 GMT+01:00 gebhard73 <[email protected]>:

Hi @gebhard73 , I've found an error during the criticalstack configuration. Is it normal?

gebhard73 · 2017-12-29T10:23:26Z

Hi, the error should only be present during installation because afterwards the mentioned configuration should be automatically written with broctl by the install script.
Please verify that these errors vanish after installation by manually executing the cron jobs.
Thanks for helping :-)

gebhard73 · 2017-12-30T19:00:28Z

Hi, any update, has it worked for you? Thanks.

ramirezversion · 2018-01-26T13:51:40Z

Hello, I have been so busy in job and with exams. Work and study is a little bit hard. This weekend I will test to execute de cron jobs manually and see what happend. For my master final job I have choose to use the foxhound deployment as a base for an IDS domestic black box and deploy a web user interface. If you feel confortable I will have for sure a lot of configurations questions for bro and the critical stack integration so If you feel confortable maybe you can help me. I have the first question, ¿how can I disable the mail notifications? Thanks and regards, 2017-12-30 20:00 GMT+01:00 gebhard73 <[email protected]>:

gebhard73 · 2018-01-30T18:39:10Z

I may suggest that you read the bro documentation to get familiar with it, e.g. https://www.bro.org/documentation/index.html

Hints:

broctl config

grep ^Mail /etc/bro/broctl.cfg | grep -v @
MailConnectionSummary = 1
MailHostUpDown = 1

broctl deploy

If foxhound works in general, please close the issue. If not, have a look at my pull requests and the issue I've opened.

ramirezversion · 2018-05-24T12:42:24Z

thanks for your kindly help. Now i have things already to work but the geoip is not working. have you done something special for it?

Thanks

gebhard73 · 2018-05-24T19:07:05Z

How do you access geoip / how do you recognize the error?

ramirezversion · 2018-05-25T05:57:07Z

I was wrong. I found the country information in the resp_cc field of connections.log. The only point is that critical stack log is not generated and i do not know how try to fix. critical stack is already istalled and in master i have the signatures downloaded. in broctl scripts loaded is already these ones... Do you find this issue too?

Thanks

gebhard73 · 2018-05-25T10:57:12Z

Glad you found it. Regarding critical stack log: can you please provide more details where you have loooked? Where have you missed the logs? Thanks!

ramirezversion · 2018-05-25T11:49:59Z

yes, I looked the following files to check if everything is ok and it seems to be.

but in the bro var log folder doesn't appear the intel.log

Am I doing something wrong related to the critical stack?

Thanks for your kindly help!

gebhard73 · 2018-05-25T12:02:45Z

thanks for the details, I'll have a look over the weekend

gebhard73 · 2018-05-27T19:16:40Z

OK, it seems that critical stack package for Pi isn't up to date anymore ...
I've analyzed severtal things, but it may come down to the following:

The string policy is missing in the load path for intel frameworks in /opt/critical-stack/frameworks/intel/feeds.bro ... and this file is re-generated wrong every time the feeds from critical-stack are updated.

Workaround:
Edit /etc/bro/site/local.bro and add these two lines, e.g. at the bottom below the critical stack entry:

@load policy/frameworks/intel/seen
@load policy/frameworks/intel/do_notice

Then run a /nsm/scripts/update .
Then trigger "malicious" traffic, e.g. get some domains (Intel::DOMAIN) from the file /opt/critical-stack/frameworks/intel/master-public.bro.dat and try to access theses on a throw-away VM. The intel.log should finally show up.

Double-check: the seen and do_notice stuff is loaded, see loaded_scripts.log

Please let me know if this helped.

ramirezversion · 2018-05-28T12:08:02Z

yeah!! it works!!! I will mention you (if you want) in my academic report so please, write me a private message or email.

ramirezversion · 2018-05-28T16:28:59Z

just last question, is there any way to add geoip location in all logs not only in the connections?

gebhard73 · 2018-05-28T19:18:11Z

hmmm - I don't think so, but you may add it using scripts:
https://www.bro.org/sphinx/frameworks/geoip.html

Perhaps use geo information one step later, e.g. in ELK? / Splunk?

ramirezversion · 2018-05-29T07:02:26Z

now i have the geolocation. i will configure in a cleaner way and maybe we can create a fork with all the integrations and config for ELK.
