Vulnerability discussion

DBMSs handling data requiring "data at rest" protections must employ cryptographic mechanisms to prevent unauthorized disclosure and modification of the information at rest. These cryptographic mechanisms may be native to the DBMS or implemented via additional software or operating system/file system settings, as appropriate to the situation.Selection of a cryptographic mechanism is based on the need to protect the integrity of organizational information. The strength of the mechanism is commensurate with the security category and/or classification of the information. Organizations have the flexibility to either encrypt all information on storage devices (i.e., full disk encryption) or encrypt specific data structures (e.g., files, records, or fields). The decision whether and what to encrypt rests with the data owner and is also influenced by the physical measures taken to secure the equipment and media on which the information resides.

Check content

Review the Cassandra Server to ensure cryptographic mechanisms are implemented preventing the unauthorized disclosure of organization-defined information at rest on organization-defined information system components. Inspect the server configuration to ensure a full disk encryption solution has been implemented. If the disk is unencrypted, this is a finding.

Fix text

Configure the Cassandra Server to implement cryptographic mechanisms preventing the unauthorized disclosure of information at rest. Implement full disk encryption such as VMcrypt or other third-party full disk encryption that uses FIPS 140-2 validated cryptography.

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.
