We're currently auditing a bunch of ASR rules, and I'm trying to pull out data from advanced hunting so that I can see which rules are safe to enable.
I was hoping someone might be able to help with aligning the ASR Rule Names with the ActionTypes used for hunting. I have found several, but there are a few I still haven't figured out.
What are the Audited/Blocked "ActionTypes" for the following rules?
Block executable content from email client and webmail
Block execution of potentially obfuscated scripts
Use advanced protection against ransomware
Block process creations originating from PSExec and WMI commands
Block Office communication application from creating child processes
Block Adobe Reader from creating child processes
Block persistence through WMI event subscription
The documentation points me to the Schema listing in the hunting console, but the only action type listed is AsrOfficeChildProcessAudited. It would be good if someone could add the rest into this list...
I have found the following ActionTypes by searching for "ASR*" they all logically line up with their rules.

@Tali Ash I see you've just posted about extensions to the schema - are you able to help with this, or at least point me to someone that can help?

@mongie105 thanks for raising it up!
We added all ASR action types into the schema reference, you will find for all description after the next update of the product(in the coming 2 weeks).

Check out the deployment guide Microsoft has developed for Microsoft Defender for Endpoint. The guide provides comprehensive instructions for configuring ASR. Additionally, the guide includes “per rule description” that provides detailed information for each rule and their appropriate action type.
Once you have the Microsoft Defender for Endpoint deployment guide open, navigate to the Configure attack surface reduction for advance configuration details section.
