SV-61115r4_rule Systems must employ cryptographic hashes for passwords using the SHA-2 family of algorithms or FIPS 140-2 approved successors.

Vulnerability discussion

Cryptographic hashes provide quick password authentication while not actually storing the password.

Check content

Determine which cryptographic algorithms are configured. # grep ^CRYPT /etc/security/policy.conf If the command output does not include the lines: CRYPT_DEFAULT=6 CRYPT_ALGORITHMS_ALLOW=5,6 this is a finding.

Fix text

The root role is required. Configure the system to disallow the use of UNIX encryption and enable SHA256 as the default encryption hash. # pfedit /etc/security/policy.conf Check that the lines: CRYPT_DEFAULT=6 CRYPT_ALGORITHMS_ALLOW=5,6 exist and are not commented out.

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.
