Identifies when a device in azure is no longer managed or compliant
Identifies when a service principal was removed in Azure.
Detects suspicious Windows Defender Application Control (WDAC) policy file creation from abnormal processes that could be abused by attacker to block EDR/AV components while allowing their own malicious code to run on the system.
Detects the usage of the 'SeLoadDriverPrivilege' privilege. This privilege is required to load or unload a device driver.
With this privilege, the user can dynamically load and unload device drivers or other code in to kernel mode.
This user right does not apply to Plug and Play device drivers.
If you exclude privileged users/admins and processes, which are allowed to do so, you are maybe left with bad programs trying to load malicious kernel drivers.
This will detect Ghost-In-The-Logs (https://github.com/bats3c/Ghost-In-The-Logs) and the usage of Sysinternals and various other tools. So you have to work with a whitelist to find the bad stuff.

Detects the removal of Sysmon, which could be a potential attempt at defense evasion
Detects an Antivirus alert in a highly relevant file path or with a relevant file name.
This event must not be ignored just because the AV has blocked the malware but investigate, how it came there in the first place.

Detects creation of the Process Monitor driver by processes other than Process Monitor (procmon) itself.
Detects process access requests to the LSASS process with specific call trace calls and access masks.
This behaviour is expressed by many credential dumping tools such as Mimikatz, NanoDump, Invoke-Mimikatz, Procdump and even the Taskmgr dumping feature.

Detects the execution of a renamed binary often used by attackers or malware leveraging new Sysmon OriginalFileName datapoint.
Detects the execution of a renamed ProcDump executable.
This often done by attackers or malware in order to evade defensive mechanisms.
