osquery pack

[arubdesu]

Hey there, I made a pack to use osquery when performing the checks instead of all of the defaults reads. Wondering if it would be something you're interested in hosting, I could give it another once-over and send a PR.
(Nice work on Downclimb, btw.)

Hey @arubdesu!

I wonder if osquery allow us to have the flexibility needed when executing other stuff than defaults stuff...

[arubdesu]

I did actively use the easier things to translate into osquery... queries, for instance the FileVault2 check, the process check to see if ScreenSharing is on, and all of the application layer firewall stuff. They're constantly adding features, always under the guiding principle that it has to be explicitly better than shelling out.
