Linux RHEL-10-600730
DISA STIG recommends
RHEL-10-600730 CAT I
RHEL 10 must employ FIPS 140-3-approved cryptographic hashing algorithms for all stored passwords.
NIST SP 800-53: IA-5(1), IA-7
Check
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
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.
