Title

The macOS system must authorize USB devices before allowing connection.

Control

Verify the macOS system is configured to authorize USB devices before allowing connection with the following command: /usr/bin/osascript -l JavaScript << EOS function run() { let pref1 = ObjC.unwrap($.NSUserDefaults.alloc.initWithSuiteName('com.apple.applicationaccess')\ .objectForKey('allowUSBRestrictedMode')) if ( pref1 == false ) { return("false") } else { return("true") } } EOS If the result is not "true", this is a finding.

Discussion

USB devices connected to a Mac must be authorized. [IMPORTANT] ==== This feature is removed if a smart card is paired or smart card attribute mapping is configured. ==== Without authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity.
