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.

Breaking down MITRE ATT&CK for ICS techniques into MON Requirements?
Olaf has a Splunk module for 'threat hunting' that's mapped to the Enterprise Mitre framework, might be a good example for some components - https://github.com/olafhartong/ThreatHunting - Note: If you just blindly install it... It's pretty rough on the search head...
What are some alternatives?
sysmon-config - Sysmon configuration file template with default high-quality event tracing
atomic-red-team - Small and highly portable detection tests based on MITRE's ATT&CK.
DetectionLabELK - DetectionLabELK is a fork from DetectionLab with ELK stack instead of Splunk.
auditd - Best Practice Auditd Configuration
SysmonForLinux
Windows-Toolkit - PS one-liner cmdlets for Windows security
SysmonTools - Utilities for Sysmon
vscode-sysmon - Visual Studio Code Microsoft Sysinternal Sysmon configuration file extension.
