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.

SIEM content development
There's a ton of valuable resources out there when searching for "detection engineering", beyond that, check https://research.splunk.com/ to get an idea of a structured and contextual approach. Beyond that, check Rob van Os Magma use case framework and any blog you can find on https://correlatedsecurity.com (Jurgen Visser). Last but not least, anything "awesome" on github, e.g. https://github.com/fabacab/awesome-cybersecurity-blueteam

Azure data sources
Some additional reading: - https://www.microsoft.com/en-us/security/blog/wp-content/uploads/2020/07/Azure-Sentinel-whitepaper.pdf - here it from the vendor; solid read as correct log sourcing/scoping is SIEM-vendor agnostic; also check the Sentinel KQL github for inspiration - https://research.splunk.com/ - your new browser startpage - check for Azure/MS/M365 rekated content

Okta Data in Splunk( Reports, Alerts and Dashboards)
Indeed, as well as the Okta analytic stories/detections at research.splunk.com. In fact, three new ones published yesterday where Okta and Splunk collaborated on detections.

Crowdstrike FDR logs to Splunk vs Splunk UF collecting logs from windows member server
Our end goal is to achieve maxium coverage against MITRE mapping. Our mapping is pretty low and the management want to achieve this in a cost effective manner. Our analysts are more comfortable with creating alerts and dashboards using standard wineventlogs. When we talk about FDR, they are like "Rabitt in the headlights". We are planning to achieve by end of 2023. https://github.com/splunk/security_content/blob/develop/docs/mitre-map/coverage.png (highlighted in blue). Some of the coverage comes native with EDR and NDR. We have a different map of that one (esp proactive one).

frustrated with lack of “entry level” security roles
Build a home lab. Phase 1: Get a good server to run VM's on. Use Proxmox as the hypervisor. Get a managed network switch (used ones on eBay are fine). Setup a span port or get a physical network TAP. Install Zeek and capture all the traffic in and out of your house. Look at the logs. Understand them. Use the free version of Suricata IDS. Examine the logs, understand them. Phase 2: Install Splunk (it has a free version). Push all the Zeek/Suricata logs to Splunk with the universal forwarder. Learn how to use Splunk. Learn the query language. Download APPs, analyze data, build dashboards, setup alerts (https://research.splunk.com/). Phase 3: Setup Honeypots, trigger them to learn how they work. Phase 4: Install Windows and Linux desktops and servers. Use the Splunk universal forwarder to dump all the logs into Splunk. Learn the logs, understand them!

Has Splunk provided any Maggie Malware fix or how to detect it ?
Checkout https://research.splunk.com for stuff like this. Just be careful regarding naming, you will more likely find accurate detections searching by the CVE number.

Best Way to Learn Query Writing?
We have over 1,000 queries (which we refer to as detections) in our publicly-available GitHub Repository in the following folder: https://github.com/splunk/security_content/tree/develop/detections

Which Antivirus do you recommend and why?
You can write your own or look at testing tools like Cytest to ensure that your business goals are met and to ensure your sensors are configured correctly, and ART for attack chains.

Exfiltration Detections
I had heard that Falcon Overwatch has a detection for Exfiltration for C2, but I was not able to trigger it using my personal Kali Machine to host a C2 server with https://github.com/cedowens/SimpleC2_Server and then used Atomic Red Team: https://github.com/redcanaryco/atomic-red-team/blob/master/atomics/T1041/T1041.md

“Malicious” powershell commands for demo
Atomic red team have tests that should trigger it, it also has a clear description of what it does and how to clean up afterwards. https://github.com/redcanaryco/atomic-red-team/blob/master/atomics/T1059.001/T1059.001.md suggest that you try obfuscation or cradle.

What are some good showcases of Collection-tactics of the MITRE ATT&CK matrix?
Are you familiar with Atomic Red Team? Many quick & practical sample tests you can often run without much effort or prep work. All tests map to Techniques - a quick way to search through them all at the Tactic level is by searching within the CSV index of all their current tests here (I counted ~50 Collection-related tests just now): https://github.com/redcanaryco/atomic-red-team/blob/master/atomics/Indexes/Indexes-CSV/index.csv
