Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Sysmon 15.0 is out now with advanced features
I was specifically using the https://github.com/olafhartong/sysmon-modular config, but once we started seeing systems crash I tried building extremely minimal configs and still found them causing hangs.

Looking for inputs and validation for this network setup.
2) There are many opensource solutions, and you hit on all the important ones. Think creativitly, and test all your controls. hit your boxes with Metaspoilt and atomic redteam. These tools will help you verify that you have the proper controls in place, and that you are able to detect attacks (successful, and failed). Run auditd with Florian Roth's rule set on your linux boxes (https://github.com/Neo23x0/auditd/blob/master/audit.rules ), and sysmon (https://github.com/olafhartong/sysmon-modular) on windows.

Is Windows Defender for Business any good?
Agree. Harden your endpoints (if unsure where to start consider hardening kitty, https://github.com/scipag/HardeningKitty) and harden Defender (https://0ut3r.space/2022/03/06/windows-defender/). Add Sysmon with a good config (https://github.com/olafhartong/sysmon-modular) and you've reached a good starting point.

Security Cadence: Sysmon (Logging Part 2 out of ?????)
Another really excellent resource (also called out by Swift) is Olaf Hartong’s Sysmon-Modular project: https://github.com/olafhartong/sysmon-modular As well as having a few full configs, Olaf’s project has modular XML configurations for each supported Sysmon Event ID. This can be incredibly helpful for fine tuning your configs.
-
splunk sysmon events
Yes absolutely. This is a very common workflow for both. One note is that you need to also find a sysmon config to use as well, and there's no easy way to manage either sysmon or its config through Splunk. Recommendations for a config are either SwiftOnSecurity's or Olaf's SysmonModular. They significantly overlap and work with each other on patches. SwiftOnSecurity's is a better pure drop-in, and Olaf's is better if you want to do customization.

Best monitoring software that works like event logs?
For some of the items you mentioned having a good sysmon config would help too. https://github.com/SwiftOnSecurity/sysmon-config or https://github.com/olafhartong/sysmon-modular are good starting points
-
Hosts making DNS queries to malicious site. How to dig deeper and find source?
I'd install sysmon if it is not already present on the infected machines, with Swift's config or Olaf's config file.
-
This Visual Studio Code extension is for heping in the writting of Sysmon XML configuration files - now supports Sysmon for Linux schema
SwiftOnSecurity's config is well commented, going through it may help. There's also sysmon-modular which seems similar.

Free Tech Tools and Resources - Connection Tracing, Throttling Tool, Log Search & More
TheHive is a versatile open-source solution for streamlining the investigation and prompt handling of security incidents. Seamlessly integrates with MISP to facilitate the transition from event analysis to investigation initiation, enabling efficient synchronization and export for collaborative threat detection and response. Moreover, coupling TheHive with Cortex empowers security professionals to efficiently analyze up to hundreds of observables. Timely-Lychee-5204 describes it as, "an open-source and scalable Security Incident Response Platform designed for handling incidents efficiently."

Incident Response: What tool workflow do you use to collaborate on and document IR?
I haven't done any IR myself, but I was thinking something like TheHive Project (open source) or similar proprietary IR toolsets would be common. But over on r/blueteamsec I just saw this post, where people claimed to be using:
-
What companies/startups are using Scala (open source projects on github)?
There are so many of them in big data, e.g. Kafka, Spark, Flink, Delta, Snowplow, Finagle, Deequ, CMAK, OpenWhisk, Snowflake, TheHive, TVM-VTA, etc.

We are a security team with 20+ years of ethical hacking, and we've defended over 2 million attacks with Blumira. Ask Us Anything.
https://thehive-project.org/ - of course :)

I want to buy a SIEM, but I don't know which one
I also recommend checking out TheHive Project and Cortex. I used these in my SOC days and was super impressed with features, like linking incidents automatically based on reported IOCs. TheHive runs on elasticsearch under the hood, too.
-
What's in your toolkit?
We used to use TheHive and really liked it. The IoC tracking and case linking was very nice. And the Cortex integrations were awesome. And then manglement dictated a single ticket system to rule them all. Since they didn't bother to purchase the IR module, we're stuck with a subpar system which I'll leave nameless.
