TMA-SAFARI-1.1
Ensure 'Open "safe" files after downloading' is 'Disabled'
Beschreibung
The Safari browser contains a feature which causes all files considered "safe" to be automatically opened once they have finished downloading. Rationale: This feature is meant to be a benefit but having the browser automatically open files that could be malicious and downloaded by mistake is a security risk. Audit reads AutoOpenSafeDownloads from the com.apple.Safari preference domain of the account running the scan (the PDF checks the same token in com.apple.Safari.plist; manual check: Follow the below steps and verify that Open "safe" files after downloading is Disabled: 1. Click Safari. 2. Click Preferences. 3. Click General. 4. Verify Open "safe" files after downloading is unchec). Safari is sandboxed, so the reading process needs Full Disk Access on macOS 10.14+. A missing key exits non-zero and is reported as FAIL even where the built-in default is compliant. Values forced by a configuration profile live in /Library/Managed Preferences and are not read here.
