SV-90789r1_rule The OS X system must restrict the ability of individuals to use USB storage devices.

Vulnerability discussion

External hard drives, such as USB, must be disabled for users. USB hard drives are a potential vector for malware and can be used to exfiltrate sensitive data if an approved data-loss prevention (DLP) solution is not installed.

Check content

If an approved HBSS DCM/DLP solution is installed, this is not applicable. To verify external USB drives are disabled, run the following command: /usr/sbin/system_profiler SPConfigurationProfileDataType | /usr/bin/grep -A 3 harddisk-external If the option "eject,alert" is not set for "harddisk-external", this is a finding.

Fix text

This setting is enforced using the "Restrictions Policy" configuration profile.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
