Details

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.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

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.)
