Ensure No World Writable Folders Exist in the System Folder

VisokaNivo 1Automatskamacos

Opis

Software sometimes insists on being installed in the /System/Volumes/Data/System Directory and has inappropriate world-writable permissions. Macs with writable files in System should be investigated forensically. A file with open writable permissions is a sign of at best a rogue application. It could also be a sign of a computer compromise and a persistent presence on the system. Folders in /System/Volumes/Data/System should not be world-writable. The audit check excludes the downloadDir and locks folders that are part of Apple's default user template.
