Check: SLEM-05-611080
SUSE Linux Enterprise Micro (SLEM) 5 STIG:
SLEM-05-611080
(in version v1 r1)
Title
SLEM 5 must employ FIPS 140-2/140-3-approved cryptographic hashing algorithms for system authentication. (Cat I impact)
Discussion
The system must use a strong hashing algorithm to store the password. The system must use a sufficient number of hashing rounds to ensure the required level of entropy. Passwords need to 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.
Check Content
Verify SLEM 5 shadow password suite is configured to encrypt interactive user passwords using FIPS 140-2/140-3-approved cryptographic hash with the following command: > sudo cut -d: -f2 /etc/shadow $6$kcOnRq/5$NUEYPuyL.wghQwWssXRcLRFiiru7f5JPV6GaJhNC2aK5F3PZpE/BCCtwrxRc/AInKMNX3CdMw11m9STiql12f/ Password hashes "!" or "*" indicate inactive accounts not available for logon and are not evaluated. If any interactive user password hash does not begin with "$6", this is a finding.
Fix Text
Configure SLEM 5 to encrypt all stored passwords with FIPS 140-2/140-3-approved cryptographic hash. Add or modify the following line in the "/etc/login.defs" file: ENCRYPT_METHOD SHA512 Lock all interactive user accounts not using SHA512 hashing until the passwords can be regenerated.
