The Infoblox DNS service member must implement NIST FIPS-validated cryptography for provisioning digital signatures, generating cryptographic hashes, and protecting unclassified information requiring confidentiality.

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.

Verify Infoblox is configured to implement NIST FIPS-validated cryptography for provisioning digital signatures and generating cryptographic hashes.

Note: For Infoblox Grids that run in FIPS mode, this requirement is Not Applicable. Refer to the Administrator Guide for more information on FIPS Mode.

1. Navigate to Data Management >> DNS >> Grid DNS Properties (Toolbar menu). 2. Toggle Advanced Mode and click on the "DNSSEC" tab. 3. Validate that all Key Signing Keys (KSKs) and Zone Signing Keys (ZSKs) use FIPS-approved algorithms. 4. When complete, click "Cancel" to exit the "Properties" screen.

If an "RSA/SHA-1" algorithm is in use, this is a finding.

Note: Ensure DNSSEC is configured to meet all other STIG requirements prior to signing a zone to avoid signing with an unapproved configuration.

1. Navigate to Data Management >> DNS >> Grid DNS Properties (Toolbar menu). 2. Toggle Advanced Mode and click on the "DNSSEC" tab. 3. Configure RSA/SHA-256 algorithms. 4. Follow manual key rollover procedures and update all noncompliant KSKs and ZSKs to use FIPS-approved algorithms.
