Severity

CAT II

CCI(s)

• CCI-000196 - The information system, for password-based authentication, stores only cryptographically-protected passwords.
• CCI-000803 - The information system implements mechanisms for authentication to a cryptographic module that meet the requirements of applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance for such authentication.

Fix Recommendation

Configure the SUSE operating system to encrypt all stored passwords with a strong cryptographic hash.

Edit/modify the following line in the "/etc/login.defs" file and set "ENCRYPT_METHOD" to have a value of "SHA512".

ENCRYPT_METHOD SHA512

Lock all interactive user accounts not using SHA512 hashing until the passwords can be regenerated.

Check Contents

Verify the SUSE operating system requires the shadow password suite configuration be set to encrypt interactive user passwords using a strong cryptographic hash.

Check that the interactive user account passwords are using a strong password 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.
