FIPS 140-2 mode must be enabled on the SUSE operating system.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity

Description
Use of weak or untested encryption algorithms undermines the purposes of using encryption to protect data. The SUSE operating system must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated. Satisfies: SRG-OS-000396-GPOS-00176, SRG-OS-000478-GPOS-00223

Check Text ( C-38047r618846_chk )
Verify the SUSE operating system is running in FIPS mode by running the following command. > cat /proc/sys/crypto/fips_enabled 1 If nothing is returned, the file does not exist, or the value returned is "0", this is a finding.

Fix Text (F-38010r618847_fix)
To configure the SUSE operating system to run in FIPS mode, add "fips=1" to the kernel parameter during the SUSE operating system install. Enabling FIPS mode on a preexisting system involves a number of modifications to the SUSE operating system. Refer to section 9.1, "Crypto Officer Guidance", of the following document for installation guidance: http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140sp/140sp2435.pdf
