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 using 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 Apache 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

In a command line, navigate to "<'INSTALLED PATH'>\bin". Run "httpd -M" to view a list of installed modules. If the "ssl_module" is not enabled, this is a finding. Review the <'INSTALL PATH'>\conf\httpd.conf file to determine if the "SSLProtocol" directive exists and looks like the following: SSLProtocol -ALL +TLSv1.2 If the directive does not exist and does not contain "ALL -SSLv2 -SSLv3", this is a finding.

Fix text

Ensure the SSLProtocol is added and looks like the following in the <'INSTALL PATH'>\conf\httpd.conf file: SSLProtocol -ALL +TLSv1.2 Restart the Apache service.

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.
