The DBMS must use NIST-validated FIPS 140-2-compliant cryptography for authentication mechanisms.

Description
Encryption is only as good as the encryption modules utilized. Unapproved cryptographic module algorithms cannot be verified and cannot be relied upon to provide confidentiality or integrity, and DoD data may be compromised due to weak algorithms. Applications utilizing encryption are required to use approved encryption modules that meet the requirements of applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance. FIPS 140-2 is the current standard for validating cryptographic modules, and NSA Type-X (where X=1, 2, 3, 4) products are NSA-certified hardware-based encryption modules. Authentication modules with weak encryption could allow an attacker to gain access to data stored in the database and to the administration settings of the DBMS.

Check Text ( C-62625r2_chk )
Check the following settings to see if FIPS 140-2 authentication/encryption is configured. If encryption is required but not configured, check with the DBA and system administrator to see if other mechanisms or third-party cryptography products are deployed for authentication. To see if Oracle is configured for FIPS 140-2 SSL/TLS authentication and/or Encryption: Verify the DBMS version: select * from V_$VERSION; If the version displayed for Oracle Database is lower than 12.1.0.2, this is a finding. If the operating system is Windows and the DBMS version is 12.1.0.2, use the opatch command to display the patches applied to the DBMS. If the patches listed do not include "WINDOWS DB BUNDLE PATCH 12.1.0.2.7", this is a finding. Open the fips.ora file in a browser or editor. (The default location for fips.ora is $ORACLE_HOME/ldap/admin/ but alternate locations are possible. An alternate location, if it is in use, is specified in the FIPS_HOME environment variable.) If the line "SSLFIPS_140=TRUE" is not found in fips.ora, or the file does not exist, this is a finding.

Fix Text (F-67663r2_fix)
Utilize NIST-validated FIPS 140-2-compliant cryptography for all authentication mechanisms. Where not already in effect, upgrade the DBMS to version 12.1.0.2 or higher. Where the operating system is Windows and the DBMS version is 12.1.0.2, install patch "WINDOWS DB BUNDLE PATCH 12.1.0.2.7" if not already deployed. Open the fips.ora file in an editor. (The default location for fips.ora is $ORACLE_HOME/ldap/admin/ but alternate locations are possible. An alternate location, if it is in use, is specified in the FIPS_HOME environment variable.)
