SV-77725r1_rule The password hashes stored on the system must have been generated using a FIPS 140-2 approved cryptographic hashing algorithm.

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 more vulnerable to compromise.

Check content

To verify the password hash setting, run the following command: # grep -i "^password" /etc/pam.d/passwd | grep sufficient If sha512 is not listed, this is a finding.

Fix text

To set the remember option, add or correct the following line in "/etc/pam.d/passwd": password sufficient /lib/security/$ISA/pam_unix.so use_authtok nullok shadow sha512 remember=5

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.
