SV-38938r1_rule The system must use a FIPS 140-2 approved cryptographic hashing algorithm for generating account password hashes.

Vulnerability discussion

Systems must employ cryptographic hashes for passwords using the SHA-2 family of algorithms or FIPS 140-2 approved successors. The use of unapproved algorithms may result in weak password hashes that are more vulnerable to compromise.

Check content

Determine if the system creates password hashes using a FIPS 140-2 approved cryptographic hashing algorithm by verifying the value of pwd_algorithm in /etc/security/login.cfg. # grep pwd_algorithm /etc/security/login.cfg If the system is not configured to generate password hashes using a FIPS 140-2 approved algorithm, such as SHA256 or a successor, this is a finding.

Fix text

Configure the system to use a FIPS 140-2 approved cryptographic hash algorithm for creating password hashes. # chsec -f /etc/security/login.cfg -s usw -a pwd_algorithm=ssha256

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.
