SV-40776r2_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 more vulnerable to compromise.

Check content

Verify the traditional UNIX crypt algorithm is deprecated. # egrep CRYPT_ALGORITHMS_ALLOW /etc/security/policy.conf If CRYPT_ALGORITHMS_ALLOW is not set, is not set to "6", or is not set to "5,6", this is a finding. Verify new password hashes are generated using either the SHA-256 or SHA-512 cryptographic hashing algorithm. # egrep CRYPT_DEFAULT /etc/security/policy.conf If CRYPT_DEFAULT is not set or is not equal to 5 or 6, this is a finding.

Fix text

Edit the /etc/security/policy.conf file. # vi /etc/security/policy.conf Uncomment or add the CRYPT_ALGORITHMS_ALLOW line and set it to "5,6". Update the CRYPT_DEFAULT default line to be equal to 5 or 6. The following lines are acceptable. CRYPT_ALGORITHMS_ALLOW=5,6 CRYPT_DEFAULT=6

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.
