RHEL 10 must employ FIPS 140-3-approved cryptographic hashing algorithms for all stored passwords.

Overview

Description
The system must use a strong hashing algorithm to store the password. Passwords must be protected at all times, and encryption is the standard method for protecting passwords. If passwords are not encrypted, they can be plainly read (i.e., clear text) and easily compromised. Satisfies: SRG-OS-000073-GPOS-00041, SRG-OS-000120-GPOS-00061

Who does this work

7 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-281221r1208797_chk)

Verify RHEL 10 employs FIPS 140-3-approved cryptographic hashing algorithms for all stored passwords for interactive user accounts with the following command: $ sudo cut -d: -f1,2 /etc/shadow nsauser:$6$kcOnRq/5$NUEYPuyL.wghQwWssXRcLRFiiru7f5JPV6GaJhNC2aK5F3PZpE/BCCtwrxRc/AInKMNX3CdMw11m9STiql12f/ Password hashes "!" or "*" indicate inactive accounts not available for login and are not evaluated. If any interactive user password hash does not begin with "$6", this is a finding.

Fix Text (F-85687r1166614_fix)

Configure RHEL 10 to employ FIPS 140-3-approved cryptographic hashing algorithms for all stored passwords. Lock all interactive user accounts not using SHA-512 hashing until the passwords can be regenerated with SHA-512.
