The EDB Postgres Advanced Server must protect the confidentiality and integrity of all information at rest.
An XCCDF Rule
Description
<VulnDiscussion>This control is intended to address the confidentiality and integrity of information at rest in nonmobile 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-generated data, 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.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Remediation - Manual Procedure
Create an encrypted partition to host the PGDATA directory. The default path for the PGDATA directory is /var/lib/edb/as<version>/data, but this will vary according to local circumstances.
This can be done at the OS level with encryption technologies provided by third-party tools.
If only certain columns need encryption, use the pgcrypto module to encrypt those columns as documented here: https://www.postgresql.org/docs/current/pgcrypto.html
