SV-38672r1_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 that are more vulnerable to compromise.

Check content

Verify no password hashes in /etc/passwd. # cat /etc/passwd | cut -f2,2 -d":" If there are password hashes present, this is a finding. Verify all password hashes in /etc/security/passwd begin with {ssha256} or {ssha512}. Procedure: # cat /etc/passwd | cut -f2,2 -d ":" # cat /etc/security/passwd | grep password If any password hashes are present not beginning with {ssha256} or {ssha512}, this is a finding.

Fix text

Change the passwords for all accounts using non-compliant password hashes. # passwd account OR # smitty passwd (This requires that GEN000590 is already met.)

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.
