Title

PostgreSQL must implement NIST FIPS 140-2 or 140-3 validated cryptographic modules to generate and validate cryptographic hashes. (Cat I impact)

Discussion

Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. The application must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated. For detailed information, refer to NIST FIPS Publication 140-2 or Publication 140-3, Security Requirements For Cryptographic Modules. Note that the product's cryptographic modules must be validated and certified by NIST as FIPS-compliant.

Check Content

First, as the system administrator, run the following to see if FIPS is enabled: $ cat /proc/sys/crypto/fips_enabled If fips_enabled is not "1", this is a finding.

Fix Text

If fips_enabled = 0, configure OpenSSL to be FIPS compliant. Configure per operating system documentation: RedHat: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/security_guide/chap-federal_standards_and_regulations Ubuntu: https://security-certs.docs.ubuntu.com/en/fips For information on configuring PostgreSQL to use SSL, see supplementary content APPENDIX-G.
