Re: event correlation on metron

Best bet there is to create a new sensor config using the grok parser type. So you would for example have a kafka topic called host_dhcp and a sensor called host_dhcp with the relevant grok pattern. Simon > On 17 Oct 2017, at 19:19, Youzha wrote: > > that’s what i

Re: event correlation on metron

that’s what i mean. what sensor that i need if i want to do this case? especially when i wanna parse some host logs into metron enrichment and indexing On Wed, 18 Oct 2017 at 01.03 Simon Elliston Ball < si...@simonellistonball.com> wrote: > What you want to do in this setting is just TailFile,

Re: event correlation on metron

What you want to do in this setting is just TailFile, the just push to Kafka. The grok piece is more efficiently handled in the Metron grok parser. Push to a kafka topic named for your sensor, then setup a sensor (a parser topology to do the grok parsing and any transformation you need). Each

Re: event correlation on metron

is there a guide of sorts we can follow, or noodle through, to write our own java based parser? or do we need to just java through and figure it out? From: Otto Fowler Sent: Tuesday, October 17, 2017 1:30 PM To: Youzha;

Re: event correlation on metron

So, There are several options parsing the data and enriching. 1. A native parser ( java ), which you have noticed is not there 2. An instance of the GROK parser, with GROK rules that parser the input 3. If it is CSV an instance of the CSV parser 4. If it is JSON an instance of the JSONMap

Re: event correlation on metron

Hi Lauren thx for your reply, yeah your suggestion absolutely right. i was able to ingest the logs to kafka. but how metron can enrich and index all of it? i think there are only bro, snort, yaf, snort, pcap, websphere topology storm on metron for parsers. so, how metron can read the logs

Re: Snort

I am so noob in all of this. I am using full-dev vm metron install to do my research. So I have 2 options to install snort: as per my understanding 1- Install it in a usual way (like that on a regular linux machine) and then make its kafka topic 2- Use ansible role to do all of that. Read the

Re: Snort

No special commands. Install and configure Snort however you like and get those logs into a Kafka topic. Metron is completely agnostic to how sensor telemetry lands in Kafka. We also have an Ansible role that will install Snort along with a simple mechanism to transport its logs to Kafka. This

Re: event correlation on metron

Hi Youzha, Either check how the snort logs on the full dev installation are ingested (I believe it's with a script) or check the Apache NiFi project which makes it very easy to read logs from almost any format and ingest them to Metron via Kafka. On 2017-10-17 08:53, Youzha wrote: > is it

Re: Snort

Ok, Now I get it. Now should I install snort in vagrant ssh in the normal way snort is usually install on a linux distro or do I need to run some special commands again? On Tue, Oct 17, 2017 at 7:45 PM, Nick Allen wrote: > In the Full Dev environment, Snort is not installed.

Re: event correlation on metron

is it possible to ingest other logs like /var/log/secure for example to be new telemetry on metron? i’ve seen the metron architecture on the website like picture below. host logs, email, av, etc can be telemetry event buffer on metron. if this possible, could you give me some suggestion how to do

Re: Snort

In the Full Dev environment, Snort is not installed. We install "Sensor Stubs" which is just a mechanism that continually replays canned telemetry logs repetitively to mimic real sensors. We have to do this because of resource constraints when running all of Metron on a single VM. See the

Re: Snort

yes,, but when i do snort -v in vagrant ssh console it says snort isnt installed where as it can be seen working in metron. Due to that reason I am confused because James Sirota said to install snort. On Tue, Oct 17, 2017 at 7:05 PM, Nick Allen wrote: > From Metron's

Re: Snort

>From Metron's perspective, Snort is just another sensor. Snort is installed, managed and executed completely independent of Metron itself. As with any sensor, you are responsible for getting the telemetry produced by Snort into Kafka. Metron can then consume that telemetry from Kafka and do

Re: event correlation on metron

If you want to look at failed login attempts for each user over time, then the Profiler might be a good solution. Your profile will depend on the fields available in your telemetry, but it would look something like this, as an example. { "profile": "failed-logins", "foreach": "user.name",

Re: event correlation on metron

for example, i wanna try to correlate between logs. how many times user A have login failed and how many times user A have login succeed. include detail IP, timestamp etc. is this possible to do with metron? On 17/10/17 02:56, James Sirota wrote: What specifically are you looking to

And I am sorry about one confusion but isnt snort builtin into the metron framework? If so then cant we access that snort and do the tasks you mentioned earlier? On Tue, Oct 17, 2017 at 11:39 AM, Syed Hammad Tahir wrote: > Hi, > > Thanks for the support. Can it be
