Vulnerability discussion

This control is intended to address the confidentiality and integrity of information at rest in non-mobile devices and covers user information and system information. Information at rest refers to the state of information when it is located on a secondary storage device (e.g., disk drive, tape drive) within an organizational information system. Applications and application users generate information throughout the course of their application use. User data generated, as well as application-specific configuration data, needs to be protected. Organizations may choose to employ different mechanisms to achieve confidentiality and integrity protections, as appropriate. If the confidentiality and integrity of application data is not protected, the data will be open to compromise and unauthorized modification.

Check content

If the application owner and Authorizing Official have determined that encryption of data at rest is NOT required, this is not a finding. Execute the following command as root: > df If the mounted filesystem where "" exists is not located on an encrypted disk partition, this is a finding.   (The default path for the postgresql data directory is /var/lib/ppas/9.5/data, but this will vary according to local circumstances.)

Fix text

Create an encrypted partition to host the "" directory. This can be done at the OS level with a technology such as db-crypt or other encryption technologies provided by third-party tools. One option is to use LUKS as documented here: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Security_Guide/sec-Encryption.html (The default path for the postgresql data directory is /var/lib/ppas/9.5/data, but this will vary according to local circumstances.)

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.
