Ensure Appropriate Permissions Are Enabled for System Wide Applications

高级别 1自动化macos

说明

Applications in the System Applications Directory (/Applications) should be world- executable since that is their reason to be on the system. They should not be world- writable and allow any process or user to alter them for other processes or users to then execute modified versions. Some application vendors use a world-writable folder for their applications. This is against the standard practice on POSIX systems.
