ElastiFlow VS Wazuh

As a matter of fact, I played with the now deprecated Elastiflow, however I couldn't get my head around managing ELK, scrapped it pretty quickly, and Netflow did not reach the meaningful stage at that time. OpenNMS looks pretty massive that I can't run it at the moment. Thanks for suggestion though.

One thing I ran for a while was security onion and utilized port mirroring to mirror the uplink port from my primary switch to my LAN on my router, so I was catching anything coming into/out of my network destined for internet. I've also used ElastiFlow ( https://github.com/robcowart/elastiflow ) which is absolutely phenomenal and awesome, I did the same and it provides some great data. You could also leverage IntelOwl ( https://github.com/intelowlproject/IntelOwl ) , one thing I have added to all my VMs is a OSSEC agent, Wazuh to be specific which is free ( https://github.com/wazuh/wazuh ) and while I am not using it to its full potential such as monitoring file deletions/modifications etc it is a powerful tool.

I'd recommend taking a look at Elastiflow (link is to the legacy version, I haven't used the pay structured tier version that replaced it) as a flow collector. Do it in a docker container, dump netflow to it, and use a sample rate that doesn't fill your collector box with flow packets after a single day. Depends on your traffic rates. We use 1 out of 250 for our rate.

Where as the newer version is (https://github.com/robcowart/elastiflow/) is called:

There is currently no feature for excluding specific SCA rules however this feature has been requested here and would be added to the roadmap for future releases.

I use Wazuh instead. Greenbone CE is severely limited and requires payment for anything beyond the very basic. Super simple installation more features.

Seems like something that should be documented somewhere more official than a random reddit post for sure. Added it to https://github.com/wazuh/wazuh/issues/1112 for good measure.

Hmm, I've really been wanting to try Wazuh but since all our endpoints (Win10/11) are running a German locale I've run into https://github.com/wazuh/wazuh/issues/16842 when checking the compliance checks (CIS benchmarks) on a test installation of 4.6.

Monitoring & Active Measures - Exporting firewall events to an external time-series database like I describe above is good to see who is touching your firewall or accessing your web site. Using an Intrusion Detection System / Intrusion Prevention System (IDS/IPS) such as open-source Suricata, which is a free package on pfSense, and deploying file system integrity monitoring, such as the open-source Wazuh on the exposed server are also good approaches to protecting yourself.

We are actively working on enhancing the system to allow users to mark vulnerabilities as "not vulnerable" or hide them. You can track the progress of this enhancement on the following GitHub issue: (Enhancement - Mark Vulnerabilities as Not Vulnerable).

Hello, thanks for using Wazuh, I will try to answer your questions: 1- I am going to check with the team in charge to see if there is a way. 2- Untriaged is a default value that is placed on vulnerabilities that do not have low, medium or high values https://github.com/wazuh/wazuh/issues/12675 3- As in the previous point, the providers of vulnerability lists have not provided the data.
