TOSS must store only encrypted representations of passwords.

DISA Rule

SV-253064r1016314_rule

Vulnerability Number

V-253064

Group Title

SRG-OS-000073-GPOS-00041

Rule Version

TOSS-04-040090

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 TOSS 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 TOSS shadow password suite configuration is set to encrypt password 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 grep -i crypt /etc/login.defs
ENCRYPT_METHOD SHA512

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