SV-65133r1_rule The system must use a FIPS 140-2 approved cryptographic hashing algorithm for generating account password hashes (login.defs).

Vulnerability discussion

Using a stronger hashing algorithm makes password cracking attacks more difficult.

Check content

Inspect "/etc/login.defs" and ensure the following line appears: ENCRYPT_METHOD SHA512 If it does not, this is a finding.

Fix text

In "/etc/login.defs", add or correct the following line to ensure the system will use SHA-512 as the hashing algorithm: ENCRYPT_METHOD SHA512

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.
