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

Description
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 Text ( C-39528r1_chk )
Determine if any password hashes stored on the system were not generated using a FIPS 140-2 approved cryptographic hashing algorithm. Procedure: # cut -d ':' -f2 /etc/passwd # cut -d ':' -f2 /etc/shadow If any password hashes are present not beginning with $5$ or $6$, this is a finding. Verify that FIPS 140-2 approved cryptographic hashing algorithms are available. # egrep '^[56]' /etc/security/crypt.conf If no lines are returned, this is a finding.

Check Text ( C-39528r1_chk )

Determine if any password hashes stored on the system were not generated using a FIPS 140-2 approved cryptographic hashing algorithm.

Procedure:
# cut -d ':' -f2 /etc/passwd
# cut -d ':' -f2 /etc/shadow

If any password hashes are present not beginning with $5$ or $6$, this is a finding.

Verify that FIPS 140-2 approved cryptographic hashing algorithms are available.
# egrep '^[56]' /etc/security/crypt.conf
If no lines are returned, this is a finding.

Fix Text (F-34652r2_fix)
If the /etc/security/crypt.conf file does not support FIPS 140-2 approved cryptographic hashing algorithms, upgrade to at least the Solaris 10 8/07 release. 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 Update passwords for all accounts with non-compliant password hashes.

# 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

Update passwords for all accounts with non-compliant password hashes.
