Vulnerability discussion

Cryptography is only as strong as the encryption modules/algorithms employed to encrypt the data. Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. NSA has developed Type 1 algorithms for protecting classified information. The Committee on National Security Systems (CNSS) National Information Assurance Glossary (CNSS Instruction No. 4009) defines Type 1 products as:"Cryptographic equipment, assembly or component classified or certified by NSA for encrypting and decrypting classified and sensitive national security information when appropriately keyed. Developed using established NSA business processes and containing NSA-approved algorithms are used to protect systems requiring the most stringent protection mechanisms."Although persons may have a security clearance, they may not have a "need-to-know" and are required to be separated from the information in question. The web server must employ NSA-approved cryptography to protect classified information from those individuals who have no "need-to-know" or when encryption of compartmentalized data is required by data classification.

Check content

Review policy documents to identify data that is compartmentalized (i.e. classified, sensitive, need-to-know, etc.) and requires cryptographic protection. Review the web server documentation and deployed configuration to identify the encryption modules utilized to protect the compartmentalized data. If the encryption modules used to protect the compartmentalized data are not compliant with the data, this is a finding.

Fix text

Configure the web server to utilize cryptography when protecting compartmentalized data.

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.
