DISA Rule

SV-248533r1015028_rule

Vulnerability Number

V-248533

Group Title

SRG-OS-000073-GPOS-00041

Rule Version

OL08-00-010110

Severity

CAT II

CCI(s)

• CCI-004062 - For password-based authentication, store passwords using an approved salted key derivation function, preferably using a keyed hash.

Weight

10

Fix Recommendation

Configure OL 8 to encrypt all stored passwords.

Edit/modify the following line in the "/etc/login.defs" file and set "[ENCRYPT_METHOD]" to SHA512:

ENCRYPT_METHOD SHA512

Check Contents

Verify that the shadow password suite configuration is set to encrypt passwords with a FIPS 140-2 approved cryptographic hashing algorithm.

Check the hashing algorithm that is being used to hash passwords with the following command:

$ sudo cat /etc/login.defs | grep -i crypt

ENCRYPT_METHOD SHA512

If "ENCRYPT_METHOD" does not equal SHA512 or greater, this is a finding.
