The EDB Postgres Advanced Server must implement NIST FIPS 140-2 or 140-3 validated cryptographic modules to provision digital signatures.

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 140-3, Security Requirements For Cryptographic Modules. Note that the product's cryptographic modules must be validated and certified by NIST as FIPS-compliant.

If a FIPS-certified OpenSSL library is not installed, this is a finding.

Run the command "cat /proc/sys/crypto/fips_enabled".

If the output is not "1", this is a finding.

For RedHat 8 or higher, run: "fips-mode-setup --check".

If the output is not "FIPS mode is enabled", this is a finding.

If fips_enabled = 0 or FIPS mode is not enabled, configure OpenSSL to be FIPS compliant.
