Vulnerability discussion

FileVault Disk Encryption must be enabled. This ensures that any data stored on the hard drive will be protected by cryptographic means when the system is powered off, mitigating the risk of unauthorized modification of that data.Selection of a cryptographic mechanism is based on the need to protect the integrity of organizational information. The strength of the mechanism is commensurate with the security category and/or classification of the information. Organizations have the flexibility to either encrypt all information on storage devices (i.e., full disk encryption) or encrypt specific data structures (e.g., files, records, or fields).

Check content

To check if FileVault 2 is enabled, run the following command: sudo fdesetup status If FileVault is 'Off', and the device is a laptop, this is a finding.

Fix text

Open System Preferences->Security & Privacy, and navigate to the FileVault tab. Use this panel to configure full-disk encryption. Alternately, from the command line, run the following command to enable FileVault: sudo fdesetup enable After FileVault is initially set up, additional users can be added.

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.
