Title
The SUSE operating system must employ FIPS 140-2 approved cryptographic hashing algorithm for system authentication (login.defs). (Cat II impact)
Discussion
Unapproved mechanisms that are used for authentication to the cryptographic module are not verified and therefore cannot be relied on to provide confidentiality or integrity, and DoD data may be compromised. SUSE operating systems using encryption are required to use FIPS-compliant mechanisms for authenticating to cryptographic modules. FIPS 140-2 is the current standard for validating that mechanisms used to access cryptographic modules use authentication that meets DoD requirements. This allows for Security Levels 1, 2, 3, or 4 for use on a general purpose computing system.
Check Content
Verify the SUSE operating system requires that the "ENCRYPT_METHOD" value in "/etc/login.defs" is set to "SHA512". Check the value of "ENCRYPT_METHOD" value in "/etc/login.defs" with the following command: > grep "^ENCRYPT_METHOD " /etc/login.defs ENCRYPT_METHOD SHA512 If "ENCRYPT_METHOD" is not set to "SHA512", if any values other that "SHA512" are configured, or if no output is produced, this is a finding.
Fix Text
Configure the SUSE operating system to require "ENCRYPT_METHOD" of "SHA512". Edit the "/etc/login.defs" file with the following line: ENCRYPT_METHOD SHA512
