Fix Recommendation

Create an encrypted partition to host the "<postgresql data directory>" 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.

If only certain columns require encryption, use pgcrypt to encrypt those columns as documented here:

http://www.postgresql.org/docs/current/static/pgcrypto.html

Check Contents

Review the system documentation to determine whether the organization has defined the information at rest that is to be protected from modification, which must include, at a minimum, PII and classified information.

If no information is identified as requiring such protection, this is not a finding.

Review the configuration of the DBMS, operating system/file system, and additional software as relevant.

If any of the information defined as requiring cryptographic protection from modification is not encrypted in a manner that provides the required level of protection, this is a finding.
