SV-83087r2_rule The DNS server must implement NIST FIPS-validated cryptography for provisioning digital signatures, generating cryptographic hashes, and protecting unclassified information requiring confidentiality.

Vulnerability 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.

Check content

Note: For Infoblox DNS systems on a Classified network, this requirement is Not Applicable. Navigate to Data Management >> DNS >> Grid DNS properties. Toggle Advanced Mode click on "DNSSEC" tab. Validate that all Key Signing Keys (KSK) and Zone Signing Keys (ZSK) utilize FIPS approved algorithms. When complete, click "Cancel" to exit the "Properties" screen. If non FIPS-approved algorithms are in use, this is a finding.

Fix text

Navigate to Data Management >> DNS >> Grid DNS properties. Toggle Advanced Mode click on "DNSSEC" tab. Follow manual key rollover procedures and update all non-compliant Key Signing Keys (KSK) and Zone Signing Keys (ZSK) to utilize FIPS-approved algorithms.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
